There is no evidence that taking large doses of vitamins provides any benefit. In rare instances, children can develop cataracts. If these are present at birth, they are called congenital cataracts. The most common symptom of a cataract is cloudy or blurred vision. Some people notice a haziness or milkiness of their vision, as if their glasses are constantly in need of cleaning.
Double vision can occur as the cataract is forming.
Some cataracts first affect reading or other types of close work. Other types of cataracts initially interfere with driving or seeing at a distance. Sometimes changing the glasses is helpful in restoring good vision. However, as the cataract worsens, stronger glasses may no longer improve sight. The appropriate time for cataract surgery depends upon the severity of your cataract and the degree to which it interferes with your normal daily activities.
