"What are cataracts?” and "Do I have cataracts?” are two of the most common questions asked during an eye examination.
What are cataracts? A cataract is formed when the lens of the eye becomes cloudy. The lens is the part of the eye that helps focus light or an image on the retina, the light sensitive tissue at the back of the eye, similar to film in cameras.
When the lens is cloudy, it will interfere with the light entering the eye and imaging on the retina. Hence, vision will be blurred or hazy. Colors will be less vivid or intense and more difficult to distinguish. There may be increased sensitivity to glare from lights, especially when driving at night and difficulty seeing at night. Reading and other routine activities become more difficult to perform.
