Cataract is the blurriness of the natural lens of the eye and it is caused over time. The lens is located behind the iris (the colored part of the eye), and can move and change shape, its function resembling that of a photographic camera lens, focusing light images on the retina.
Almost all people develop cataract. People over fifty and more often over seventy develop cataract symptoms.
Symptoms of Cataract
Frequent change of prescription glasses
Appearance of “halos” around lights during the night.
