A cataract is also known as a “curtain on the eye” among people. It is an eye disease that occurs when the natural lens of the eye becomes dull and loses its transparency with various stains on its surface. In the initial stage of cataract, it manifests itself with symptoms such as blurring of near vision and fading in perceived colors. However, as the process progresses, problems in both near and far vision increase.
Cataracts are more common in people aged 60 and over due to aging. This is because the human eye is the sensory organ most rapidly affected by the aging process. However, the opinion that the disease is only seen in advanced ages does not fully reflect the truth. Because congenital, genetic, and environmental factors are also effective in the emergence of certain types of disease. Cataracts, which is the most common eye problem that causes permanent vision loss in the world, is seen in approximately 25 million people every year. Due to the intense effect of sunlight, the incidence of the disease is higher in hot regions such as Africa and South America.
