Astigmatism is a refractive error that causes blurred vision due to an irregularly shaped cornea or lens. This irregularity prevents light from focusing properly on the retina, leading to distortion at both near and far distances. Individuals with astigmatism experience vision that appears stretched or elongated, regardless of the distance of the object being viewed.
Addressing astigmatism is crucial for clear vision and overall visual comfort. Historically, corrective lenses like glasses and contacts were the primary solutions. However, modern refractive surgery techniques offer options for reducing or eliminating astigmatism, improving visual acuity and reducing dependence on corrective eyewear. Effective management of this condition can significantly enhance quality of life.
