Astigmatism is a disorder of the eyes that can cause the light to focus on two points instead of just one point because the cornea is misshapen. This causes people to have blurry, slanted or distorted vision. While you may think it only happens in one eye, the truth is most of the time it occurs in both eyes and the shape of the cornea is virtually the same in both eyes.
While astigmatism in both eyes can be passed down from generation to generation, sometimes it can happen in just the one eye, but this is usually the result of some traumatic injury that has caused some kind of damage to the eye.
Causes of Astigmatism
Astigmatism is actually quite a common problem and a large number of people around the world suffer from it. There are a number of factors that might cause Astigmatism. Firstly, it could be that your cornea is irregularly shaped. If it is flatter or more curved than normal, it will result in your vision being distorted.
It can also be caused by the crystalline lens being tilted. This will cause your vision to become blurry. Furthermore, if you have heavy tissue around the eye or an abnormal eyelid, it can push down on the eye itself and cause it to become misshaped.
Having said this, there is no scientifically proven reason why people face this problem. It can be caused for a number of different reasons.
There are many different symptoms that can occur as a result of astigmatism. These symptoms could occur by themselves or you might have some of them at the same time. In any case, if you have any of these symptoms, it is always advisable to visit your eye care specialist as soon as possible as they will be in the best position to help you.
It should be noted that some of these symptoms might not neccessarily be caused by astigmatism, but instead might be caused by another vision problem.
- Blurry or Distorted Vision
- Eye Fatigue
If you notice that the quality of your vision is deteriorating, you should see an eye doctor who will give you an eye exam and advise the next course of action and treatment.
Tests for Astigmatism
There are a few tests that your eye doctor will carry out to check if you have astigmatism or not. Firstly they will measure the reflected light in your eye. They will measure this light on the surface of the cornea using an instrument called a keratometer that will show both the orientation and amount of astigmatism in the eyes.
Secondly, the eye doctor will measure the curvature of the cornea. They will also measure the curvature of your cornea’s surface using a keratoscope. This will be able to tell the doctor about the degree of astigmatism that you are facing. This process is called corneal topography.
There are a range of different treatments available if you are diagnosed with astigmatism. Some people are given corrective lenses for this condition, but they are not always the best solution.
Corrective lenses can actually weaken your vision over time and cause your eyes to become more reliant on them. As time goes by, you will need to get stronger glasses or contact lenses to counteract this weakening process.
Another option is surgery, but there are big risks involved with surgery. The most common type of eye surgery is laser, but this can be expensive and give you unwanted side effects. One of the biggest dangers associated with surgery is that it might go wrong and you could end up with no sight at all.
Before your resort yourself to either having to get corrective lenses or surgery, you should consider eye exercises because they can help you to enhance your vision and correct the symptoms that can be caused by astigmatism.
Your eyes contain a muscle that is used to focus and like other muscles in your body, this particular one will also be strengthened with regular exercise. There are a range of different exercises available that can help with blurry vision and other focusing problems. Try to read a book without any glasses then look away in the distance to a different object and focus on it. Then go back to the book and focus on the printed words again. Continue to do this for a few minutes or until your eyes become tired.
On top of eye exercises, you should consider your diet. In order for your body to function properly, you need to ensure that you are getting the right vitamins and minerals in your diet. Your eyes will also make use of these vitamins and minerals to stay in good shape.
Therefore, before you opt for expensive corrective lenses and dangerous surgery, you should give eye exercises and vitamin supplements a chance to help you deal with astigmatism.
Dealing with Astigmatism
There are many causes of astigmatism and it can have some very negative effects on the quality of your vision. People are often quick to resort to corrective lenses or surgery to fix problems and this isn’t always the best approach to deal with vision issues.
Getting the right amount of vitamins and minerals in your diet will also help your vision. Exercises and a healthy diet can help you to reduce vision problems and keep your eyes in the best condition possible for as long as possible.
