How long does it take for cataracts to develop?

There is no way to predict how rapidly a cataract will develop. There are many kinds of cataracts and they can develop very slowly or progress rapidly. Usually, if one can determine their speed of development in the past few years, an educated guess can be made as to how rapidly they will develop over the next few years. There is no guarantee that the speed of cataract development will not increase or decrease in the future. Your ophthalmologist will be happy to provide you with his best estimate during your comprehensive eye examination.
