The lens of the eye is normally transparent. If a cloudy area develops in the lens, it is called a cataract. Vision becomes increasingly poor as light passing through the cataract is decreased and scattered. Early symptoms include glare and sensitivity to bright light. Later, as the cataract continues to worsen, haloes may appear around lights. Vision often becomes blurred, hazy and foggy.
