Light rays enter our eyes through the cornea, pupil and lens. These light rays are focused on the retina, a light sensitive tissue lining the back of the eye.
While 70% of the eyes focusing power comes from the cornea, it is the lens that helps to fine tune our focusing ability. In the healthy eye the lens is clear
and allows light rays to pass through unobstructed. As a cataract forms the lens gradually becomes cloudy. As light passes through this cloudy lens it is no
longer clearly focused on the retina, causing images to appear hazy or blurred. Watch the video below to get a description of the cataract or
