Unveiling The Secrets Of Blurry Night Vision

Night astigmatism is a condition that causes blurry vision at night or in low-light conditions. People with night astigmatism may also experience glare and halos around lights.

Night astigmatism is caused by an irregular curvature of the cornea, the clear outer layer of the eye. This irregularity prevents light from focusing properly on the retina, the light-sensitive tissue at the back of the eye. As a result, vision becomes blurry.

Night astigmatism is a common condition, affecting up to 30% of the population. It is often diagnosed during a routine eye exam. Treatment for night astigmatism includes eyeglasses, contact lenses, or refractive surgery.
