What Causes Astigmatism to Worsen

Astigmatism refers to the term in which your cornea or lens isn’t round in shape. It’s a common vision disorder, and its symptoms include blurred vision, difficulty with driving at night, headaches, eye pain, and glare sensitivity. Astigmatism usually develops in childhood and changes our eye shape into a football-like shape from its usual spherical form.

This unusual shape causes light rays to bend in more than one direction, which causes blurred vision. Astigmatism usually doesn’t require any surgeries, and in most cases, you can treat it with glasses or contact lenses but if left untreated several factors can cause Astigmatism to worsen.

contact lenses for astigmatism

Astigmatism is a disorder of the eye where the irregularly shaped cornea causes blurred vision, discomfort, and headaches. Most people have some degree of astigmatism. Astigmatism often co-exists with myopia (nearsightedness), and hyperopia (farsightedness).

Usually, the surface of the cornea is round, like a basketball. For people with astigmatism, the surface is shaped like a football, and the eye is not able to focus light rays to a single point.

Astigmatism can be easily corrected with eyeglasses or contact lenses. Contact lenses provide a clearer, and a wider field of vision, and provide greater comfort than glasses.

The type of contact lens you have depends on the type of astigmatism you have. Your ophthalmologist will be able to prescribe the right type of contacts for your condition. The contact lens for you could be one of the following:

Types of Contact Lens for Astigmatism

  1. Toric Contact Lenses – Toric contact lenses are specially designed to correct moderate amounts of astigmatism. These are made of either a hydrogel material or a highly breathable silicone hydrogel. The word Toric comes from the geometric shape ‘torus.’ A torus looks like a donut, and Toric lenses are shaped like a slice of a donut so they align with the irregularly shaped cornea to give the wearer proper vision. Toric contact lenses need to be prescribed by the doctor who can choose contact lenses that are right for your vision and customize them accordingly.
  2. Gas Permeable Contact Lenses – Gas permeable contact lenses can correct astigmatism without being shaped like a Toric. These contacts for astigmatism are rigid and retain their spherical shape instead of molding to the irregular shape of the cornea. This uniform curve of the gas permeable contact lens replaces the irregularly shaped cornea as the primary refracting surface of the eye. It takes more time fitting gas permeable contact lenses as compared to fitting soft contact lenses and costs more than getting fitted with Toric lenses. Almost 75% of the astigmatic participants said that their vision was better with gas permeable contact lenses. Out of the test subjects, only 10% had worn their gas permeable contact lenses prior to the study, and 60% ended up wearing these gas permeable lenses after the study.
  3. Hybrid Contact Lenses – Hybrid contact lenses are great for most patients with corneal astigmatism. Hybrid contact lenses combine the best of both worlds — the center is made of a rigid gas permeable material, and the surrounding zone is made of a hydrogel or a silicone hydrogel like in Toric lenses. This helps the wearer provide the comfort of Toric lenses and the accuracy of vision of gas permeable contacts for astigmatism. Since these are more customized contacts for astigmatism, they need more time and expertise in fitting. But since these lenses are custom-made for the wearer, they’re more sturdy and better to wear for sports.

Most people with mild astigmatism (up to 0.50D) can wear soft, disposable contact lenses that don’t have any correction for astigmatism. You can still achieve 20-20 vision with a small amount of uncorrected astigmatism.

The experienced team at the InSight Vision Center will help you get the best contact lens, no matter what your level of astigmatism is. Make an appointment now.

Vision with Astigmatism

It’s not every day that you see people talking about interesting facts about eyesight. But how much do you know about your eye health? There are some who are blessed with perfect 20/20 vision, while others are completely blind.

But what about people with certain eye conditions? How can you tell if you have poor vision at all? Twitter’s recent post has spread like wildfire and fuelled responses from around the world. It’s making people question their eyesight. The below tweet shows what vision with astigmatism looks like versus vision without astigmatism.

This post intends to do some detailed analysis of the facts this tweet wants to communicate and, along the way, spread awareness about how people with astigmatism see!

Astigmatism vs Normal – How people with Astigmatism see?

In the first image, the light from the brake lights and traffic signs appear distorted, stretching into a wide, starburst shape. This exactly indicates what vision with astigmatism looks like. In the second image, the lights coming off of the traffic light appear softer and have a halo shape, which represents clear vision.

This tweet has gathered over 80,000 reactions and has convinced many people that they have vision with astigmatism. Most of the people who reacted thought the image on the left was a representation of perfect vision, and the results have shocked them. Some people with glasses thought the distorted vision was actually a normal condition.

Astigmatism Lights at Night

Due to Astigmatism the misshapen cornea or lens doesn’t allow proper light intake in your eyes. The lights get scattered instead of focusing on your retina. Therefore if you have astigmatism, you need to squint your eyes more. You may also find yourself reducing the glares of the things in front of you whenever possible.

And the interesting part is that people born with astigmatism may never know this difference until someone points that out to them. Therefore the Twitter post caught the attention of so many people with astigmatism who thought what they see is normal.
But if you are amongst those who developed astigmatism over time, you will gradually, if not instantly, know that something is wrong with your vision. It’s easy to spot the difference between astigmatism visions vs. normal vision. Astigmatism lights notoriously appear hazy with holes, glares, and streaks.

Driving at Night With Astigmatism

By now, you may understand what astigmatism vision looks like at night if the processing of lights is so distorted normally. Yes, astigmatism gets pretty worse at night. Specifically, it’s scary to drive at night with astigmatism.

Unlike daytime, there is more darkness all-around at night. So naturally, your pupils dilate to allow more light inside the eye. But with astigmatism, more light means more glare. The street lights and headlights of other vehicles help people with normal vision navigate the roads at night. But these lights become a hurdle if you have astigmatism vision.

Now you know the different effects of astigmatism at night vs. normal daytime. It’s much worse and more confusing during the night. In the next section, let’s deep dive into the solution for people driving with astigmatism at night. Keep reading if you are one of them!

Tips for Safely Driving at Night With Astigmatism

Your eye doctor will agree that the following tips help combat astigmatism lights at night while driving.

  1. Get Your Vision Corrected
  2. Getting your vision corrected is essential since most critical decisions made by drivers are based on sight. Many drivers aren’t aware of the relationship between good vision and good driving, especially if you drive at night.

    There are two vision correction options to make life easy for you. The first one is glasses. It’s a proven solution for astigmatism at night. Otherwise, you can get toric lenses. However, you may need some time to get used to them. Figure out what works best for you with the help of your eye doctor.

  3. Wear Anti-Reflector Glasses
  4. If you choose good old glasses for astigmatism at night, get anti-reflector ones. They are much less likely to intensify glare than other corrective lenses. They can also help cut down on poor vision in low light, helping you drive at night.

    If you already wear glasses and think you are comfortable in them, try the anti-reflectors glasses and know the difference.

  5. Use Contact Moisturizing Drops
  6. Having to deal with painful, irritated eyes while driving can be not only annoying but also dangerous. Toric lenses for astigmatism often result in dry eyes. Driving at night can also result in a glare that reflects off the dry, irregular surface of the cornea.

    If you wear contact lenses to correct astigmatism, use contact moisturizing drops to prevent drying your toric lenses.

  7. Get a LASIK Eye Surgery
  8. LASIK eye surgery refers to laser eye surgery and vision correction. It’s considered the permanent solution to the everyday annoyances of dealing with corrective lenses when you have astigmatism.

    With a quick recovery rate, LASIK eye surgery can save you money on the annual costs of glasses and contact lenses. And more importantly, it will help you with a better vision to allow you to drive safely.

Parting Words

Driving at night with astigmatism is a severe life hazard. Therefore, you must not only do your own vision analysis. You also must show these pictures to your family members and loved ones to check which image they identify with.

The issue of astigmatism lights can easily be resolved with solutions like glasses, toric lenses, and LASIK eye surgery. Also, an eye exam is important not just to correct astigmatism vision but it is to safeguard your overall health and wellness.

Don’t put it off for any longer. A doctor of optometry can diagnose astigmatism. Schedule an appointment with an experienced optometrist in Fresno, CA to correct your vision.

Eye vitamins

Most people with astigmatism are born this way. It’s a natural condition. In rare cases, astigmatism can result from eye injury or surgery. Astigmatism stems from a bend in the cornea in a way which distorts light.

Almost everyone has some degree of astigmatism because their vision is not perfect. Symptoms include blurry vision, headaches, squinting, and poor night vision. The most common symptom of astigmatism is blurred or double-vision. Children often don’t recognize these symptoms because they don’t really know that they have an eye condition. Early astigmatism treatment can significantly reduce distorted vision and other associated problems.

Eye doctors can quickly and easily confirm astigmatism with a vision test. If a doctor finds blurred vision at all distances, they know it is astigmatism. Tests done to measure the cornea for contacts can also find problem areas.

Astigmatism often comes with other vision problems. Blurry vision up close or far away can mean near or farsightedness. Often prescriptions for eyeglasses will include distance and astigmatism both. But treatment for astigmatism also includes eye vitamins. What you eat has a huge impact on your eye health and overall well-being. Eating right is the key to correcting minor vision problems.

Here Are Some Important Eye Vitamins That Help to Control Astigmatism:

1. Vitamin A
Vitamin A is excellent for good eye health. Natural sources of vitamin A include dark leafy vegetables like spinach and kale, carrots, and winter squash. Including these vegetables in your regular diet will ensure you’re getting all the vitamins you need for good vision. If you don’t particularly like the taste of spinach and kale, add them to your smoothies! Carrots, added to other vegetables like cabbage and tomatoes make an excellent choice for soups.

2. Vitamin B
Vitamin B will encourage good vision. Fish like salmon, trout, and catfish are also an excellent source of Vitamin B. Eggs, dairy, poultry, beef, and lamb also make a good addition to your meals. Vegans and vegetarians too can get their source of protein through avocados.

3. Vitamin C
Does your diet include enough citrus foods? Vitamin C is essential for your overall health and also encourages good vision. While supplements are easily available, it’s best that you eat natural foods that contain Vitamin C. Oranges, lemons, dark leafy vegetables, strawberries, and peppers are all rich in Vitamin C.

If natural foods do not suffice, your doctor will recommend other methods to treat astigmatism to regain your distorted vision after conducting a test.

Here Are 2 Astigmatism Correction Methods:


1. Eyeglasses or Contact Lenses
The most common way to treat astigmatism is by recommending corrective lenses. Your doctor will prescribe a particular pair of soft lenses called toric. These contact lenses help to bend more light in a specific direction than the other. In more severe cases, you may require a gas-permeable rigid contact lens. Astigmatism treatment also includes the use of eyeglasses to treat vision problems.

2. Early Intervention
Remember that both children and adults are susceptible to the symptoms of astigmatism. And it’s important that you and your little one visit the doctor’s office for an annual eye exam to determine potential eye conditions. A delay in astigmatism correction can lead to frequent headaches, lethargy, and fatigue. For kids, it can also hinder their learning ability at school. Kids who are passionate about co-curricular activities may also lose out on great opportunities if they have poor vision. Adults, on the other hand, may not be able to sit in front of the screen for long hours.

If you or a family member is facing vision problems to a certain degree, it’s important that you seek treatment immediately. Book an appointment with Insight Vision Centre today for comprehensive eye care.

Eye exercise to treat astigmatism

Astigmatism is a very common eye disorder that affects your vision. The muscles around the eyes are affected and they cause undue stress on the cornea. This stress causes the cornea to lose its shape, which in turn causes blurry vision. The other symptoms of astigmatism include double vision, eyestrain, eye irritation, and headaches.

Astigmatism could be prevalent at birth or could be a result of trauma, congenital conditions or eye surgery. The condition can be very annoying as it makes a simple task like reading a book complicated. However, there are natural ways to treat astigmatism and one of them is eye exercises.

Benefits of Eye Exercises for Astigmatism

It may sound unbelievable, but it’s true. Eye exercises are known to treat astigmatism. Just like the other muscles in our body, our eye muscles work on a simple logic; you need to use them or else you lose them. Therefore, it is essential that you keep your eye muscles active throughout the day. Just by staring straight at the computer screen or at the road ahead while driving doesn’t exercise the muscles to their full potential. Additional eye exercises are a must. Below are some benefits of eye exercises:

  • They help reduce the stress.
  • They strengthen the eyes and relax the eye muscles.
  • They improve vision over time or in as little as 1 to 4 weeks.

Below are 8 exercises you can do at home to treat astigmatism.

Exercise 1. Rectus muscle relaxation
Benefit: This exercise relaxes the rectus muscles, which reduces the stress on the cornea and also strengthens the muscles around the eyes. It should be done 2 to 4 times a day.
The exercise should be done in the following steps:

  1. Place your thumb over your nose at a 90-degree angle.
  2. Move it clockwise to 12 o’clock position. Keep it there for 2-3 seconds and then bring it back. Make sure your eyes follow your thumb.
  3. Now move the thumb to 1 o’clock position, keep it there for 2-3 seconds and move it back to the original position (90-degree angle).
  4. Repeat this for all clock positions.
  5. Don’t forget to breathe properly during this exercise.

Exercise 2. Eye Massage

facts about astigmatism

Most people have some degree of astigmatism and yet there are so many people who are still confused and may miss out on signs of astigmatism. Here are some common facts about astigmatism and the symptoms you should look out for and the steps you can take to treat them.

Facts about Astigmatism:

  1. Irregularly-shaped Cornea
    Astigmatism is caused by an irregularly-shaped cornea which makes it look more like a football than a normal spherical-shape structure. A cornea with a rounder shape controls the amount of light that enters, allowing you to see things around you clearly. An irregularly-shaped cornea prevents an even distribution of light, resulting in blurred vision.
  2. Genetic Component
    An irregularly-shaped cornea is a genetic trait, just like the color of your eyes that may have passed from one generation to the next. So, if you start experiencing blurry vision over time, it may be unquestionably out of your control.
  3. Untreated Astigmatism
    Astigmatism symptoms should be caught early, especially in children. If overlooked, it can result in more serious and permanent conditions like amblyopia, commonly known lazy eye. Regular eye exams should be an essential part of your child’s growing years to avoid further complications.
  4. Astigmatism affects Depth Perception
    The ability to see in three dimensions and judge the distance of an object is called depth perception. Eye conditions like astigmatism make depth perception issues more prominent. This makes it difficult to determine the proximity of certain objects or the distance between two objects. Astigmatism blurs the edges and outlines of things you see. So even if your depth perception is not affected, the overall quality of your vision may be poor nonetheless.
  5. More than One Category of Astigmatism
    Astigmatism has more than one category. An irregular-shaped cornea is called corneal astigmatism. While the shape of the lens being distorted is known as lenticular astigmatism. Both result in distorted vision when looking at objects near and far.
  6. LASIK surgery
    Lasik surgery can permanently reshape the cornea, guiding it to a rounder shape that helps you see clearly. Expect a sharper than ever vision without having to deal with corrective lenses.
  7. High Blood Sugar Levels
    High blood sugar levels can affect the shape of the lens that is responsible for the focusing power of the eye. Eye problems are collectively referred to as diabetic eye disease. It commonly includes diabetic retinopathy, where the tiny blood vessels in the retina are damaged, but may also include cataracts and glaucoma.
  8. Vigorous rubbing of the eyes
    Constantly rubbing your eyes can cause damage to the cornea and eventually result in increased pressure and irregular change in the shape of the eye.
  9. Degrees of Severity
    A person with mild astigmatism has < 1.00 dioptre, a person with moderate astigmatism has 1.00 to 2.00 dioptres, a person with severe astigmatism has 2.00 to 3.00 dioptres and a person with extreme astigmatism has > 3.00 dioptres. People with astigmatism may suffer from headaches, tired eyes and experience sensitivity to bright lights. At times, near-sighted people may squint to improve their vision.
