Astigmatism
verified Medically reviewed by Dr. Liron Bittan, O.D. · Updated March 2026
Astigmatism is a common refractive error where the cornea or lens has an irregular shape — more like a football than a basketball — causing blurred or distorted vision at all distances. It affects roughly 1 in 3 people and is easily corrected with glasses, toric contact lenses, or LASIK surgery. Astigmatism is not a disease and does not worsen with screen use.

When Should You See an Eye Doctor for Astigmatism?
If you experience persistent blurry vision, frequent headaches after visual tasks, or difficulty driving at night, schedule a comprehensive eye exam to check for astigmatism. Even mild astigmatism can cause eye fatigue and reduced clarity. Children who squint frequently or tilt their heads to see should be evaluated promptly.
