Astigmatism

Astigmatism is an eye condition where the cornea or lens displays irregular curvature. As a result, light refracts improperly or imprecisely on the retina causing blurry vision depending on the distance. A large number of individuals live with mild astigmatisms because perfectly shaped eyes are exceptionally rare. Poor night vision, frequent eye strain, repeated squinting and excessive eye fatigue after viewing lit screens are all signals of possible astigmatism.
The irregularity is thought to be hereditary and is more frequently found in Hispanic and Asian populations. Today, optometry has several effective treatments for astigmatisms including refractive surgery and a full range of corrective lenses. If you think you have an astigmatism, schedule a standard eye examination.
