Eye contact cause

Cataracts
Cataracts happen to be another of the most widely existing eye problems. The formation of cloudy areas in the eye lens is referred as the cataracts. Light passes through a clear eye lens to your retina (just like a camera), where images are processed. With cataracts affecting your eye lens, light cannot pass through to the retina smoothly enough.

As a result, you are unable to see as clearly as people without cataracts and may also notice a halo or glare around lights at night.
