Cataracts cloud the vision and make it appear as though there is a film covering the natural lens of the eye. This is a progressive condition that can be treated conservatively in its beginning stages.
What are cataracts?
Cataracts occur when the normally clear lens of the eye becomes cloudy or discolored, obstructing light from properly reaching the retina. This results in images appearing blurred, dull, or distorted. Although cataracts can develop in individuals of any age, they are more commonly found in older patients. In fact, about two-thirds of adults over the age of 60 experience some degree of cataracts.
Initially, cataracts may not affect vision at all. However, as the condition progresses, corrective lenses may become necessary to improve eyesight. In severe cases, cataracts can cause such significant vision loss that glasses and other conservative treatments are no longer effective, and surgery becomes the only option.
