Cataracts are the leading cause of blindness all over the world. They result in clouded lenses which are easily treated in their early stages and can be treated with surgery if you qualify for the procedure. Despite the fact that they’re so common, it’s still important to understand what can cause cataracts so you know what to expect if you develop them.
The most common cause of cataracts is aging, with half of Americans having some type of cataract by the age of 75. Genetics can also play an important role if you have a family history of the condition. Other causes can be controlled or managed, such as smoking, UV exposure, and diabetes. One surprising cause of cataracts is eye injuries, which can result in the development of cataracts much earlier than normal.
