Very simply put, astigmatism means that your eyes aren’t entirely round like they’re supposed to be. When your eyes aren’t entirely round, this can cause light to bend differently when it hits your eye, and distant objects may appear blurry.
Can Astigmatism Cause Headaches or Double Vision?
Yes, astigmatism may lead to headaches because your eyes are working so hard to get the images you’re viewing in focus. They need to work harder than they should, which can eventually lead to headaches. Astigmatism can also give you double vision when the picture is out of focus. Both of these symptoms could be an indicator of astigmatism, and you should consult with an eye doctor.
What Causes Astigmatism?
We aren’t sure what the causes astigmatism. Most people are born with it, but it is also possible to get astigmatism after an eye injury or eye disease. You have a more significant chance of getting astigmatism when your relatives have it, suggesting a genetic component in the cause of this condition.
Can Astigmatism Correct Itself?
In children, when the eye is still developing, astigmatism may change and get better or worse. After the age of 25, however, there is little change in astigmatism. If you only suffer from a very mild form of astigmatism, then this may go away over time. This is the usually the kind of astigmatism that you don’t notice or are not alarmed by.
Is Astigmatism Correctable with Glasses, Contacts or Lasik Surgery?
Glasses or contact lenses are capable of correcting most forms of astigmatism. The problem is caused by the cornea, which is the lens of the eye so that a correctable lens will help. Lasik surgery is an option for some people with astigmatism. During this surgery, the cornea is being reshaped which can correct astigmatism completely. A certain amount of the cornea tissue is removed from under cornea to reshape the cornea and make the eye fully round again.
