Understanding Astigmatism
Astigmatism arises from the irregular curvature of the cornea or lens, causing light to focus unevenly on the retina. This condition can lead to blurry vision at all distances and may also cause discomfort, eye strain, and headaches. The severity of astigmatism varies, and many individuals may not even realize they have it, making regular eye exams crucial for detection and treatment, as suggested by sources like the American Academy of Ophthalmology (AAO) and the National Eye Institute (NEI).

When selecting contact lenses for astigmatism, consider the following factors:
1. Type of Astigmatism
