Cataracts can also occur for geographical reasons or progress faster.
Exposure to UV (ultraviolet) rays from the sun can damage the skin, as well as cause cataracts and other eye diseases. UV rays can damage lens proteins, causing cataracts. Cataract disease is observed to be more common, especially on the African continent, where hot weather prevails and the sun's rays fall steeply and intensively. In addition, causes such as nutritional deficiency, lack of sanitation due to water restrictions and sandstorms can also be factors in the emergence of cataract on the African continent or its more widespread progression than on other continents.
