What Are the Symptoms of Cataracts?
Cataracts are a condition that affects over half of Americans that are over the age of 80. Roughly 11 million Americans have some type of macular degeneration. Over the past decade, research has indicated that nutrition can help to lower the risk and the progression of macular degeneration.
How Do Cataracts Form?
Cataracts form where light enters through the pupil, which is the round, black part of the eye that is in the center of the iris. Located behind the pupil, the lens allows light entering the eye to be focused onto the retina at the back of the eye.
A cataract forms when the protein fibers of the lens undergo a change in shape and become clumped together. This results in a clouding of the lens of the eye which is normally transparent. The process that occurs here is someone similar to an egg white turning white as is cooks.
The cataracts can develop over many years. However, before the cataract is noticed by the outside, the vision can become cloudy or blurring. Other symptoms of cataract include problems seeing at night, faded color vision and bright lights that seem to have a halo or starburst effect to them.
