What is sticmatism eye?

Astigmatism is a common eye condition that occurs when the cornea or lens is not perfectly round. This causes light to be focused at different points on the retina, resulting in blurred vision.

Astigmatism can cause a variety of symptoms, including:

* Blurred vision

* Distorted vision

* Eyestrain

* Headaches

* Double vision

* Light sensitivity

Astigmatism is usually diagnosed during an eye exam. The doctor will use a variety of tests to measure the shape of the cornea and lens and determine the degree of astigmatism.

Astigmatism can be corrected with eyeglasses, contact lenses, or surgery. Eyeglasses or contact lenses can help to focus light correctly on the retina, while surgery can change the shape of the cornea or lens.

Types of astigmatism

There are two main types of astigmatism:

* Regular astigmatism is the most common type. It occurs when the cornea or lens is not perfectly round in one direction.

* Irregular astigmatism occurs when the cornea or lens is not perfectly round in more than one direction.

Causes of astigmatism

Astigmatism is usually caused by a genetic defect. It can also be caused by eye injuries or diseases.

Treatment for astigmatism

Astigmatism can be corrected with eyeglasses, contact lenses, or surgery.

* Eyeglasses or contact lenses can help to focus light correctly on the retina.

* Surgery can change the shape of the cornea or lens.

The type of treatment that is best for you will depend on the severity of your astigmatism and your individual preferences.
