Unravel The Mystery: Astigmatism Lights At Night

June 19, 2024

Astigmatism is a common vision condition that causes blurred vision. The blurry vision is a result of the cornea, the clear front cover of the eye, being irregularly shaped. This irregular shape causes light to be focused in more than one place on the retina, the light-sensitive tissue at the back of the eye. Astigmatism can cause difficulty seeing both near and far objects. It can also cause eye strain, headaches, and double vision.

Astigmatism is often discovered during routine eye exams. Optometrists will perform a series of tests to determine the shape of the cornea and the degree of astigmatism. Once diagnosed, astigmatism can be corrected with eyeglasses, contact lenses, or refractive surgery.

If you experience blurred vision or other symptoms of astigmatism, it is important to schedule an eye exam with your optometrist to discuss your treatment options.
