How do I know if I have a cataract?
See your ophthalmologist. Your doctor will conduct a thorough examination of your eyes and can determine if you have a cataract or if there are other factors causing your symptoms. Cataracts tend to develop gradually when they are associated with the aging process, but when they are found in younger people or people with diabetes, they can progress at a much quicker pace. However, since cataracts can develop at a different rate even from your left eye to your right, it is impossible to accurately predict how fast they will progress.
