In this article, we’ll delve into some of the most prevalent eye issues people face today, providing essential information for readers to understand, prevent, and manage these conditions. So, let’s embark on a journey to uncover the world of common eye problems.
Myopia (Nearsightedness)
What is Myopia?
Myopia, commonly known as nearsightedness, is a common eye condition that affects how well a person can see distant objects. Individuals with myopia can see nearby objects clearly, but distant objects appear blurry. This condition occurs when the eyeball is longer than normal or the cornea (the clear front surface of the eye) is too curved. As a result, light entering the eye is focused in front of the retina instead of directly on it.
What are the symptoms of myopia?
Blurred Distant Vision: Individuals with myopia often experience blurred vision when trying to see objects in the distance, such as road signs or distant landmarks.
Squinting: Squinting is a common natural response to myopia. It temporarily changes the shape of the eye’s lens, helping to focus light on the retina and improve vision.
Eye Strain: Myopia can lead to eye strain, especially when trying to see distant objects for an extended period. This can result in discomfort, headaches, or tired eyes.
Difficulty Seeing the Board or Screen: Myopic individuals may have trouble seeing what’s displayed on a chalkboard, whiteboard, or screen in a classroom or office, particularly if they are sitting at a distance.
Difficulty Recognizing Faces from a Distance: Recognizing people or details from a distance can be challenging for individuals with myopia.
Sensitivity to Light (Photophobia): Some myopic individuals may experience increased sensitivity to bright lights or glare, which can be uncomfortable.
Difficulty Driving: Myopia can make it challenging to read road signs or see objects far ahead while driving, especially at night.
It’s important to note that these symptoms can vary in severity depending on the degree of myopia. If you or someone you know is experiencing these symptoms, it’s advisable to consult an eye care professional for a comprehensive eye examination. They can diagnose myopia and recommend appropriate corrective measures, such as eyeglasses or contact lenses, to improve vision and alleviate these symptoms.
How do you treat myopia?
Treating myopia typically involves the use of corrective lenses or refractive surgery. The choice of treatment depends on the degree of myopia, individual preferences, and the guidance of an eye care professional. Here are the common methods for treating myopia:
Glasses: Glasses are a common and effective way to correct myopia. A prescription from an eye care professional will specify the lenses needed to correct your nearsightedness. Glasses provide clear vision by refracting light directly onto the retina, compensating for the eye’s focusing problem.
Contact Lenses: Contact lenses are an alternative to eyeglasses and can provide a more natural field of vision. They come in various types, including soft and rigid gas-permeable lenses. Contact lenses are fitted to your specific prescription and should be used and cared for according to the guidance of your eye care professional.
Orthokeratology (Ortho-K): Ortho-K is a non-surgical approach to myopia management. Special rigid contact lenses are worn overnight, reshaping the cornea temporarily. During the day, you can see clearly without the need for glasses or lenses. This method is often used in children to slow the progression of myopia.
Refractive Surgery: In cases of moderate to high myopia, refractive surgery may be an option. Procedures like LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy) reshape the cornea permanently to improve vision. These surgeries require a consultation with a refractive surgeon to determine candidacy and discuss potential risks and benefits.
Regular Eye Examinations: Regardless of the chosen treatment method, regular eye examinations are essential to monitor the progression of myopia, especially in children. Early intervention and treatment adjustments can help manage myopia effectively.
It’s crucial to work closely with an eye care professional to determine the most suitable treatment for your myopia. They will consider your specific prescription, age, lifestyle, and any other individual factors to provide the best course of action to correct and manage your nearsightedness.
Hyperopia (Farsightedness)
What is Hyperopia?
Hyperopia, commonly known as farsightedness, is an eye condition in which distant objects are seen more clearly than nearby objects. It occurs when light entering the eye is focused behind the retina instead of directly on it. This happens because the eyeball is typically too short or the cornea has too little curvature, resulting in light rays converging behind the retina.
What are the symptoms of hyperopia?
Some common symptoms of hyperopia include:
Blurred Near Vision: Farsighted individuals often experience difficulty seeing objects up close, such as when reading a book, working on a computer, or doing any close-up tasks.
Eyestrain: Straining the eyes to see up-close objects is a common symptom of hyperopia. This can lead to discomfort, headaches, or tired eyes, especially during tasks that require close visual focus.
Difficulty with Close Tasks: People with hyperopia may have trouble with activities that demand sharp near vision, like threading a needle or reading fine print.
Squinting: Squinting is a natural reaction to farsightedness. When individuals squint, they effectively reduce the amount of light entering the eye, which can improve their ability to see nearby objects more clearly.
Eye Fatigue: Hyperopia can lead to eye fatigue or strain, particularly if individuals spend extended periods doing close-up work without correction.
Asthenopia: Asthenopia is a term used to describe general eye discomfort, including symptoms like eye pain, burning, or a sensation of heaviness. These symptoms can be associated with hyperopia.
It’s important to note that the severity of these symptoms can vary depending on the degree of hyperopia. If you or someone you know is experiencing these symptoms, it’s advisable to consult an eye care professional for a comprehensive eye examination.
How do you treat hyperopia?
The choice of treatment depends on the degree of hyperopia, individual preferences, and the guidance of an eye care professional. Here are the common methods for treating hyperopia:
Glasses: Glasses are a straightforward and effective way to correct hyperopia. A prescription from an eye care professional specifies the lenses needed to correct farsightedness. These lenses bend incoming light so that it focuses directly on the retina, improving near and distance vision.
Contact Lenses: Contact lenses provide an alternative to glasses and can offer a more natural field of vision. Soft contact lenses are commonly used to correct hyperopia, although rigid gas-permeable lenses are an option as well. Contact lenses are fitted to your specific prescription and should be used and cared for according to the guidance of your eye care professional.
Refractive Surgery: In cases of moderate to high hyperopia, refractive surgery may be an option. Procedures like LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy) reshape the cornea to improve vision permanently. These surgeries require a consultation with a refractive surgeon to determine candidacy and discuss potential risks and benefits.
Reading Glasses: Some individuals with mild hyperopia may choose to use over-the-counter reading glasses for close-up tasks. Reading glasses are a simple and affordable solution for correcting mild farsightedness.
Bifocal or Progressive Lenses: These specialized eyeglasses or contact lenses have two or more prescription strengths in one lens. They can be used to correct both hyperopia and presbyopia (difficulty focusing on close objects due to age-related changes).
It’s essential to work closely with an eye care professional to determine the most suitable treatment for your hyperopia. They will consider your specific prescription, age, lifestyle, and any other individual factors to provide the best course of action to correct and manage your farsightedness.
Astigmatism
What is Astigmatism?
Astigmatism is a common refractive error of the eye that causes blurred or distorted vision. It occurs when the cornea (the clear, front surface of the eye) or the lens inside the eye has an irregular shape rather than being perfectly spherical. This irregular shape prevents light from focusing properly on the retina, leading to blurred or distorted images at all distances.
What are the symptoms of Astigmatism?
The symptoms of astigmatism may include:
Blurred Vision: Blurred vision is the most common symptom of astigmatism. Objects at various distances can appear fuzzy or out of focus. Both near and distant vision can be affected.
Distorted or Wavy Vision: Astigmatism can cause objects to appear distorted or slightly bent. Straight lines may appear curved, and details may not appear as they should.
Eyestrain: Trying to compensate for astigmatism by squinting or straining the eyes to see more clearly can lead to eyestrain. This may result in discomfort, tiredness, or headaches, especially after prolonged visual tasks.
Difficulty with Night Vision: Astigmatism can worsen night vision. Glare, halos around lights, or double vision in low-light conditions are common complaints.
Difficulty Reading or Using a Computer: People with astigmatism may find it challenging to read, work on a computer, or engage in tasks that require focusing on objects up close.
Frequent Changes in Eyeglass Prescription: If you notice that your eyeglass prescription changes frequently, it might be an indication of astigmatism. Regular eye examinations are important to monitor and adjust the prescription as needed.
It’s important to recognize these symptoms and seek professional eye care to diagnose and correct astigmatism.
How do you treat Astigmatism?
Here are the common methods for treating astigmatism:
Glasses: Glasses are a simple and effective way to correct astigmatism. A prescription from an eye care professional specifies the lenses needed to correct the irregular shape of the cornea or lens, allowing light to focus properly on the retina. Glasses can provide clear vision for both near and distant objects.
Contact Lenses: Contact lenses, particularly toric contact lenses, are designed to correct astigmatism. These lenses have different powers in different meridians to compensate for the uneven curvature of the cornea. Contact lenses provide a more natural field of vision and are suitable for people with an active lifestyle.
Refractive Surgery: Refractive surgery may be an option for some individuals with astigmatism, particularly when the astigmatism is significant and stable. Procedures like LASIK (Laser-Assisted In Situ Keratomileusis) or PRK (Photorefractive Keratectomy) can reshape the cornea, correcting astigmatism and reducing the need for eyeglasses or contact lenses. Refractive surgery should be discussed with an eye care professional to determine candidacy and discuss potential risks and benefits.
Orthokeratology (Ortho-K): Ortho-K is a non-surgical approach that uses specially designed rigid contact lenses to reshape the cornea temporarily while you sleep. During the day, you can see clearly without the need for eyeglasses or contact lenses. Ortho-K is often used to correct astigmatism in children and may also slow the progression of myopia.
It’s essential to work closely with an eye care professional to determine the most suitable treatment for your astigmatism.
Presbyopia
What is Presbyopia?
Presbyopia is a common age-related vision condition that affects the eye’s ability to focus on objects up close. It typically becomes noticeable in one’s 40s and progresses with age. Presbyopia occurs as a result of changes in the eye’s crystalline lens and its surrounding muscles, which make it difficult for the lens to change shape effectively for near focusing.
What are the symptoms of presbyopia?
The primary symptom of presbyopia is difficulty seeing objects up close. Some common symptoms of presbyopia include:
Difficulty Reading Small Print: People with presbyopia often find it challenging to read small print, such as the text in books, newspapers, or on a mobile phone or tablet.
Needing More Light: Individuals with presbyopia may require brighter lighting when doing close-up tasks to improve their ability to see clearly.
Holding Objects at Arm’s Length: To see objects up close more clearly, individuals with presbyopia tend to hold them at arm’s length. This can be observed when reading a book or looking at a menu, for example.
Eyestrain: Straining the eyes when trying to focus on close objects can lead to discomfort and eyestrain. This may result in headaches or tired eyes, especially after prolonged reading or other near tasks.
Difficulty with Fine Tasks: Tasks that require precise near vision, such as threading a needle or working on detailed crafts, become more challenging for those with presbyopia.
Blurred Vision at Close Range: Blurred vision is a common symptom of presbyopia when trying to focus on objects up close. This blurriness can make it difficult to see text clearly.
Near Vision Improvement in Good Lighting: Some individuals may notice that their near vision improves when they have ample light, but the difficulty persists in dimly lit environments.
It’s important to recognize these symptoms and seek professional eye care to diagnose and correct presbyopia.
How do you treat presbyopia?
Here are the common methods for treating presbyopia:
Reading Glasses: Reading glasses are a simple and effective way to correct presbyopia. They are available over-the-counter (OTC) or by prescription and are specifically designed to provide clear vision for close-up tasks. Reading glasses are convenient and suitable for many people with presbyopia.
Multifocal Glasses: Multifocal Glasses, also known as progressive or bifocal lenses, have two or more prescription strengths in one lens. These lenses allow clear vision for both near and distant objects, eliminating the need to switch between different pairs of glasses.
Contact Lenses: Multifocal contact lenses are available for those who prefer not to wear glasses. These lenses have different prescription strengths for near and distant vision. They provide clear vision at various distances and are suitable for individuals with presbyopia.
Monovision Contact Lenses: Monovision contact lenses involve correcting one eye for near vision and the other for distance vision. While it may take some adjustment, many people find this a suitable solution for presbyopia.
Refractive Surgery: Refractive surgery procedures, such as monovision LASIK or PRK, can be considered for those who want a surgical solution to correct presbyopia. These procedures reshape the cornea to improve near and distant vision.
Corneal Inlays: Some individuals with presbyopia may consider corneal inlays, which are small implants placed in the cornea to improve near vision. This is a surgical option that can be discussed with an eye care professional.
If you are experiencing any of these symptoms, book an appointment to see our in-house opticians.
The choice of treatment depends on the individual’s vision needs, lifestyle, and the guidance of an eye care professional.
Remember, regular eye examinations are essential to monitor and manage these conditions effectively, and working closely with an eye care professional is crucial to determine the most suitable treatment for your specific needs.

How to Insert and Remove Contact Lenses
Inserting and removing contact lenses might seem daunting at first, especially for those who are new to wearing them. However, with a bit of practice and proper technique, the process becomes much easier. Here’s a step-by-step guide on how to insert and remove contact lenses:
Inserting Contact Lenses
Before you begin, thoroughly wash your hands with soap and water. Dry them with a lint-free towel to ensure cleanliness.
Check the lens for any damage or debris. Make sure it’s not inside out. A lens that’s properly oriented should resemble a bowl shape.
Place the lens on the tip of your index finger, using your other hand’s fingers to hold your upper eyelid and lashes.
Use the fingers of your free hand to hold down your lower eyelid, creating a space for the lens.
Look straight ahead or slightly upward, then gently place the lens onto your eye. Try to avoid blinking as the lens touches your eye.
Slowly release your eyelids and blink a few times. The lens should settle into a comfortable position. If the lens feels uncomfortable, use your clean finger to gently adjust it.
Removing Contact Lenses
As always, start by washing your hands thoroughly and drying them with a lint-free towel.
Look upward, and with your index finger, gently pull down your lower eyelid.
Use your index finger and thumb to pinch the lens gently. If you have hard or gas-permeable lenses, they might pop out easily. Soft lenses may require a slight squeeze.
Once you’ve pinched the lens, simply slide it down to the white part of your eye (sclera). You can then easily pick it up from there.
If the lens is reusable, clean it as per your eye care provider’s instructions. If it’s a daily disposable lens, you can discard it.
Tips for Success
Practice Patience: Inserting and removing contact lenses can take some practice. Be patient and don’t rush the process.
Use a Mirror: Performing these steps in front of a mirror can be helpful, especially in the beginning.
Relax: Relax your eye muscles while inserting and removing lenses. Tensing up can make the process more difficult.
Follow Care Instructions: Always follow your eye care provider’s instructions for cleaning, storing, and replacing your lenses.

It is important to follow the instructions provided by your optician and the contact lens manufacturer. If you experience any discomfort or problems with your contact lenses, remove them immediately and see your optician.
Myopia control contact lenses, also referred to as orthokeratology (Ortho-K) lenses, present a promising avenue for managing and slowing down the progression of myopia. These specialised lenses serve a dual purpose: providing clear vision during the day and working behind the scenes to curb the advancement of nearsightedness.
How Do They Work?
Ortho-k lenses are designed to be worn overnight while you sleep. They gently reshape the cornea – the eye’s clear front surface – temporarily altering its curvature. This change in corneal shape allows light to focus more precisely on the retina, correcting the refractive error associated with myopia. It’s a bit like wearing a retainer for your eyes, but the effects are not permanent and need to be maintained through regular lens wear.
Consultation and Customisation
Before embarking on the journey of myopia control with contact lenses, it’s crucial to consult with a qualified optometrist. A comprehensive eye examination will determine the suitability of Ortho-K lenses for your eyes. Each individual’s eye anatomy is unique, and an experienced optometrist can ensure proper fitting, assess the potential risks, and guide you through the process.
Maintaining Eye Health
While myopia control contact lenses offer promising benefits, responsible lens care and eye health maintenance are paramount. Regular follow-up appointments with your optometrist will monitor the progress of your myopia control and address any concerns that may arise.
Myopia Control Lenses for Children and Teenagers
Myopia-control contact lenses offer several significant benefits for children and teenagers, making them a compelling option for managing and slowing down the progression of myopia. Here’s how these specialised lenses can positively impact young individuals:
Slower Myopia Progression: One of the primary advantages of myopia-control contact lenses for children and teenagers is their ability to slow down the progression of nearsightedness. Research suggests that these lenses can significantly reduce the rate at which myopia worsens over time. This is crucial because high levels of myopia are associated with a higher risk of eye health complications later in life.
Reduced Risk of High Myopia: By slowing down myopia progression, myopia control contact lenses can help reduce the risk of developing high myopia (severe nearsightedness). High myopia is associated with an increased likelihood of eye conditions like retinal detachment, glaucoma, and macular degeneration. Starting myopia control early can potentially mitigate these risks.
Better Academic Performance: Children and teenagers often spend a significant amount of time on near tasks like reading and studying. Myopia-control contact lenses can help maintain better visual acuity for these tasks, potentially leading to improved academic performance and reduced eye strain.

In the quest for optimal health, we often prioritise aspects like exercise, sleep, and mental well-being. However, one vital component that shouldn’t be overlooked is the impact of our diet on our eyes. Just as a balanced diet is essential for overall well-being, it plays a crucial role in maintaining good eye health. In this article, we will explore the fascinating connection between diet and eye health, and discover which nutrients are essential for promoting and preserving healthy vision.
The Power of Antioxidants
Antioxidants are superheroes when it comes to eye health. They help combat oxidative stress caused by harmful molecules called free radicals, which can damage the cells in our eyes over time. Including antioxidant-rich foods in our diet can help protect our eyes from age-related macular degeneration (AMD), cataracts, and other eye conditions. Some notable antioxidants include:
Vitamin C: Found abundantly in citrus fruits, berries, and leafy greens, vitamin C aids in reducing the risk of cataracts and slowing the progression of AMD.
Vitamin E: Almonds, spinach, and sunflower seeds are excellent sources of vitamin E. This nutrient protects our eyes from damage caused by free radicals and may reduce the risk of cataracts and AMD.
Beta-Carotene: Our bodies convert beta-carotene into vitamin A, which is crucial for maintaining good vision. Carrots, sweet potatoes, and dark leafy greens are rich in beta-carotene and can promote healthy eyes.
Omega-3 Fatty Acids
Omega-3 fatty acids are essential fats that play a significant role in eye health. The two main types of omega-3s found in fish, flaxseeds, chia seeds, and walnuts are docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). DHA, specifically, is a major structural component of the retina and is vital for visual development and retinal function. Omega-3s help reduce the risk of dry eyes, macular degeneration, and glaucoma.
Lutein and Zeaxanthin
Lutein and zeaxanthin are two essential carotenoids found in the macula, the central part of the retina responsible for clear and sharp vision. These nutrients act as natural sunscreens, filtering harmful high-energy blue light and protecting the delicate cells in the macula from damage. Green leafy vegetables like spinach and kale, egg yolks, and corn are excellent sources of lutein and zeaxanthin.
Maintaining Stable Blood Sugar Levels
Uncontrolled blood sugar levels can lead to a condition known as diabetic retinopathy, which damages the blood vessels in the retina. To maintain stable blood sugar levels, it is essential to consume a well-balanced diet that includes whole grains, lean proteins, healthy fats, and plenty of fruits and vegetables. Avoiding sugary drinks and processed foods is also crucial in preventing blood sugar spikes that can harm your vision.
Staying properly hydrated is essential for overall health, including eye health. Dehydration can cause dry eyes and contribute to eye strain. Ensure you drink an adequate amount of water throughout the day, especially in dry environments or during prolonged screen time.
Diets for Specific Eye Conditions
Tailoring your diet to address specific eye conditions can provide additional support. Here are some diet recommendations for common eye conditions:
Diet for Macular Degeneration
For macular degeneration, incorporate foods rich in omega-3 fatty acids, lutein, zeaxanthin, and antioxidants. Dark leafy greens, fish, and colourful fruits and vegetables should be the foundation of your diet.
Diet for Glaucoma
A diet rich in antioxidants, specifically vitamins C and E, can support eye health in cases of glaucoma. Include citrus fruits, berries, almonds, and sunflower seeds in your daily meals.
Diet for Dry Eyes
Stay hydrated and include foods rich in omega-3 fatty acids, such as fatty fish and flaxseeds. Consuming foods high in vitamin A and vitamin C can also be beneficial.
Diet for Cataracts
To reduce the risk of cataracts, prioritise a diet rich in antioxidants and vitamin C. Colorful fruits and vegetables, especially citrus fruits, can provide the necessary nutrients.
While genetics and age play a role in our eye health, our dietary choices can significantly influence the long-term well-being of our eyes. By incorporating various antioxidant-rich foods, omega-3 fatty acids, lutein and zeaxanthin, and maintaining stable blood sugar levels, we can nourish our eyes and potentially reduce the risk of developing age-related eye conditions. Remember, a balanced diet is not only beneficial for our overall health but also a key ingredient in maintaining healthy vision throughout our lives. So let’s make wise dietary choices and see the world through a clear and vibrant lens!
When it comes to eye health, there are numerous eye health myths and misconceptions that often cloud our understanding of how to best care for our eyes. In this article, we aim to dispel the most common eye health myths and shed light on the truth, helping you maintain optimal vision and protect your precious eyesight.
Eye Health Myth 1: Sitting too close to the TV or computer screens damages your eyes.
While sitting too close to screens for prolonged periods can cause eye strain and fatigue, it does not permanently damage your eyes. The discomfort experienced is often temporary and can be alleviated by following the 20-20-20 rule: every 20 minutes, take a 20-second break and focus on something 20 feet away.
Eye Health Myth 2: Reading in dim light harms your eyes.
Reading in dim light may strain your eyes and lead to temporary discomfort, but it does not cause any permanent damage. Adequate lighting is important to reduce eye strain and ensure comfortable reading, but it does not affect the long-term health of your eyes.
Eye Health Myth 3: Wearing someone else’s glasses can damage your eyes.
Wearing someone else’s glasses may cause some discomfort or visual distortion, but it does not harm your eyes. However, it is essential to wear glasses prescribed specifically for you to achieve optimal vision correction and prevent unnecessary strain.
Eye Health Myth 4: Eating carrots will significantly improve your vision.
Carrots contain vitamin A, which is crucial for good vision, but consuming excessive amounts of carrots will not give you superhuman eyesight. A balanced diet with a variety of fruits and vegetables, including carrots, can contribute to overall eye health but cannot correct existing vision problems.
Eye Health Myth 5: Squinting worsens your eyesight.
Squinting is a natural response to enhance focus and clarity temporarily. It does not cause any permanent damage or worsen your eyesight. However, if you find yourself frequently squinting, it might be a sign of an underlying vision problem, and it is recommended to schedule an eye examination.
Eye Health Myth 6: Eye exercises can reverse nearsightedness or other vision problems.
While eye exercises can help alleviate eye strain and improve focus, they do not reverse or correct vision problems like nearsightedness, farsightedness, or astigmatism. These conditions are typically caused by the shape of the eye and are best corrected with glasses, contact lenses, or refractive surgeries.
Eye Health Myth 7: Staring at the sun during a solar eclipse is harmless if you squint or wear sunglasses.
Looking directly at the sun, even during an eclipse, can cause severe damage to your eyes, regardless of whether you squint or wear sunglasses. The intense solar radiation can harm the retina, leading to permanent vision loss. Always use certified solar eclipse glasses or indirect viewing methods to protect your eyes.
Eye Health Myth 8: Using artificial tears will make your eyes dependent on them.
Artificial tears are a safe and effective way to relieve dryness and lubricate the eyes. They do not cause dependency or make your eyes “lazy” over time. If you frequently experience dry eyes, it is important to consult an eye care professional to identify and address the underlying cause.
Eye Health Myth 9: Using your eyes too much will ‘wear them out.’
Your eyes are designed to work hard, and they won’t ‘wear out’ if you use them too much. However, it is important to take breaks from using your eyes every 20-30 minutes, to prevent eye strain.
Eye Health Myth 10: Wearing eyeglasses that are too strong or have the wrong prescription will damage your eyes.
Wearing eyeglasses that are too strong or have the wrong prescription will not damage your eyes. However, it can make it difficult to see, and it can also lead to headaches and eye strain.
Eye Health Myth 11: Wearing eyeglasses will weaken your eyes.
Wearing eyeglasses will not weaken your eyes. In fact, it can actually help to strengthen your eyes by providing them with the support they need to focus properly.
Eye Health Myth 12: Crossing your eyes will make them permanently crossed.
This is not always true. In some cases, crossing your eyes can lead to amblyopia, which is a condition where one eye is weaker than the other. However, this is usually only a problem in children. In adults, crossing your eyes will not usually cause any lasting damage.
Eye Health Myth 13: Having 20/20 vision means your eyes are perfectly healthy.
Having 20/20 vision is just one measure of eye health. It does not mean that your eyes are free of any problems. There are many other eye conditions that can affect your vision, even if you have 20/20 vision.
It’s important to remember that these are just myths. There is no scientific evidence to support them. If you have any concerns about your eye health, it’s always best to see an eye doctor.
Here are some additional tips for improving your eye health:
Get regular eye exams: Regular eye exams are crucial for detecting any potential issues early and maintaining optimal eye health.
Wear sunglasses when you’re outdoors: Protect your eyes from harmful UV rays by wearing sunglasses that block 100% of both UVA and UVB rays.
Eat a healthy diet: Include foods rich in antioxidants, omega-3 fatty acids, and vitamins C and E in your diet to support overall eye health. Examples include leafy green vegetables, fish, citrus fruits, and nuts.
Get enough sleep: Sufficient sleep is essential for eye health and helps prevent eye fatigue and dryness.
Manage stress: High stress levels can contribute to eye strain and other vision problems. Practice stress management techniques like meditation or deep breathing exercises.
Quit smoking: Smoking has been linked to an increased risk of various eye conditions, including macular degeneration and cataracts. Quitting smoking can significantly improve your eye health. For help quitting smoking follow this is link.
By following these tips, you can help to keep your eyes healthy and protect your vision for a lifetime. Remember, accurate information and regular eye care are essential for maintaining optimal eye health.
Astigmatism is a common eye condition that affects many people. It occurs when the shape of the cornea or lens is irregular, causing distorted vision. Astigmatism can cause blurred or fuzzy vision at any distance, making it difficult to see clearly. However, the good news is that this condition is very treatable with the right tools and care.
What causes Astigmatism?
Astigmatism occurs when the cornea (the clear front surface of the eye) or the lens inside the eye has an irregular shape, causing light rays to focus unevenly on the retina at the back of the eye. This can result in blurry or distorted vision at any distance.
The specific causes of astigmatism are not always clear, but several factors are known to contribute to its development, including:
Genetics: Astigmatism can run in families, and people with a family history of this condition are more likely to develop it themselves.
Eye injuries: Injuries or trauma to the eye can cause changes in the shape of the cornea or lens, leading to astigmatism.
Eye surgery: Certain types of eye surgery, such as cataract surgery, can cause astigmatism as a side effect.
Keratoconus: This progressive eye disease causes the cornea to be thin and bulge into a cone-like shape, resulting in astigmatism.
Age-related changes: As we age, changes in the shape and flexibility of the lens inside the eye can cause astigmatism and other vision problems.
Corneal scarring: Scarring of the cornea due to injury, infection, or disease can cause astigmatism.
It’s important to note that astigmatism can also occur in combination with other vision problems, such as nearsightedness (myopia) or farsightedness (hyperopia).
What are the symptoms of Astigmatism?
The symptoms of astigmatism can vary from person to person and can range from mild to severe. Some people may not even be aware they have astigmatism until they undergo a comprehensive eye exam. However, some common symptoms of astigmatism include the following:
Blurred or distorted vision: This is the most common symptom of astigmatism. People with astigmatism may have difficulty seeing objects clearly at any distance.
Headaches: Straining the eyes to compensate for blurred or distorted vision can lead to frequent headaches.
Eye fatigue: Squinting or straining the eyes to see clearly can cause eye fatigue or discomfort, especially after prolonged reading, computer work or other close activities.
Difficulty seeing at night: Astigmatism can make it difficult to see objects in low light conditions, such as driving at night.
Double vision: In some cases, astigmatism may cause double vision, where one image appears as two overlapping or adjacent images.
Eye strain: Astigmatism can cause eyestrain or tired eyes, especially after prolonged activities that require a lot of visual efforts, such as reading, driving or using digital devices.
Diagnosing and treating astigmatism can help you achieve clear and comfortable vision, and reduce the risk of further eye problems.
If you are experiencing any of these symptoms, book an appointment to see our in-house opticians.
Astigmatism is typically diagnosed during a comprehensive eye exam with an optometrist or ophthalmologist. The exam may include several tests to evaluate the shape and function of the eyes, including:
Visual acuity test: This test measures how well you can see letters on an eye chart from a distance.
Refraction test: This test measures the way your eyes bend or refract light and helps determine your prescription for corrective lenses.
Keratometry: This test measures the curvature of the cornea, the clear front surface of the eye, using a special instrument called a keratometer.
Corneal topography: This test maps the surface of the cornea using computerized imaging technology.
Retinal exam: This test examines the retina, the light-sensitive tissue at the back of the eye, to ensure it is healthy.
If you have symptoms of astigmatism or a family history of the condition, your optician may perform additional tests to evaluate the shape and function of your eyes.
Once a diagnosis of astigmatism is made, your optician will work with you to develop a treatment plan that may include corrective lenses, such as glasses or contact lenses, or refractive surgery, depending on the severity of your condition and your personal preferences.
It is recommended that adults undergo a comprehensive eye exam at least once every two years, while children and people with certain health conditions may require more frequent eye exams. Regular eye exams can help detect and treat astigmatism and other eye problems early, preventing complications and preserving your vision.
Can I prevent Astigmatism?
Unfortunately, there is no known way to prevent astigmatism, as it is often a result of the natural shape and growth of the eye. However, there are some steps you can take to reduce your risk of developing other eye problems that may contribute to astigmatism, including:
Get regular eye exams: Regular eye exams can help detect and treat eye problems early, preventing complications and preserving your vision.
Protect your eyes: Wear protective eyewear when engaging in activities that could cause eye injuries, such as sports or home repairs.
Practice good eye hygiene: Wash your hands before touching your eyes, and avoid sharing eye makeup or contact lenses to reduce the risk of eye infections.
Maintain a healthy lifestyle: Eating a healthy diet rich in fruits and vegetables, getting enough sleep, and managing chronic health conditions can help maintain overall eye health.
Take breaks from digital devices: Long hours of staring at a computer or smartphone screen can cause eyestrain and dry eyes, which may worsen astigmatism symptoms.
While these steps may not prevent astigmatism, they can help maintain good eye health and reduce the risk of other eye problems that could contribute to astigmatism or other vision problems.
How do I treat Astigmatism?
The treatment for astigmatism depends on the severity of the condition and the preferences of the individual. Mild astigmatism may not require treatment, while more severe cases may require corrective lenses or surgery. Here are some common treatments for astigmatism:
Glasses: Prescription eyeglasses with cylindrical lenses can be used to correct astigmatism. These lenses have different curvatures in different parts of the lens, which compensate for the uneven curvature of the cornea and help focus light properly on the retina.
Contact lenses: Toric contact lenses are designed specifically to correct astigmatism. These lenses have different powers in different parts of the lens to correct the uneven curvature of the cornea.
Orthokeratology (Ortho-K): This is a non-surgical treatment that uses special rigid contact lenses to reshape the cornea overnight while you sleep, resulting in improved vision without the need for glasses or contacts during the day.
Refractive surgery: In some cases, refractive surgery, such as LASIK or PRK, can be used to reshape the cornea and correct astigmatism. During these procedures, a laser is used to remove a small amount of tissue from the cornea, which changes its shape and improves vision.
It’s important to note that while glasses and contact lenses can effectively correct astigmatism, they do not cure the condition. Refractive surgery can provide a more permanent solution, but it is not always suitable for everyone and carries some risks and potential side effects.
If you have astigmatism, it’s important to discuss your treatment options with an optician. They can evaluate the severity of your condition, your personal preferences, and your overall eye health to recommend the best course of treatment for you.
In conclusion, astigmatism is a common eye condition that affects many people. While it can be frustrating to deal with, it is very treatable with the right tools and care. If you are experiencing symptoms of astigmatism, it is important to schedule an appointment with your optician as soon as possible. With the right diagnosis and treatment, you can enjoy clear, comfortable vision once again.
