What is astigmatism, and how can it be corrected?

It occurs because the cornea at the front of the eye is unevenly curved. Eyesight problems, such as astigmatism, are also known as refractive errors. Astigmatism is a common condition that can be corrected by glasses or contact lenses, or cured with laser eye surgery.

How bad can astigmatism get?

A high degree of astigmatism, of over four diopters, will cause significant vision problems. Straight lines may appear wavy, making driving a vehicle or operating machinery not only difficult, but dangerous. Having astigmatism is different from near or farsightedness because blurry vision occurs at all distances.

What are the two causes of astigmatism?

There are two causes of astigmatism: corneal and lenticular: The cornea is the clear dome-shaped structure at the front of the eye. When light enters the eye, the cornea is the very first surface in our eyes to focus or bend the light.
