Information for parents about pediatric astigmatism, including causes, symptoms and what it means for your child's vision.
Astigmatism is caused by a misshapen cornea or lens, which makes it difficult for the eye to focus light. This can cause squinting to focus or reduce glare perceived from light sources.
There are a few common types of astigmatism, including regular, irregular, corneal and lenticular astigmatism, which typically fall into one of three categories: myopic, hyperopic and mixed astigmatism.
Astigmatism is a condition that causes blurry, fuzzy or distorted vision at any distance. It is caused by imperfections in the curvature of the cornea or the lens (or both).
Glasses for astigmatism are among the most popular treatment methods. Special lens brands and features are available to correct astigmatism.
