Eye Diseases



Astigmatism is a fairly frequent corneal abnormality, which is when the shape of the eye is not only irregular, but shaped like a football.

In certain cases, the lens of the eye can present an irregular form, and can develop astigmatism.

When you have astigmatism, your vision is not precise, nor completely clear. Your optometrist will suggest correcting this problem by adding a cylinder to your glasses or your contact lenses.

Having a perfectly round cornea is rather rare. Most people are affected by astigmatism, but when it is weak, correction with glasses is not necessary.

You should know that Bellevue clinics have all the latest technologies available to diagnose and monitor cases of astigmatism.
