Pictures of different types of eye cataracts are available at an online atlas of ophthalmology, such as the one associated with the University of Iowa Department of Ophthalmology and Visual Science. There are many cataract pictures for different cataract types, including brunescent, cerulean, congenital, nuclear and anterior polar cataracts.
Some other types of common cataracts are cortical and subcapsular cataracts. Cataracts are a cloudy film that forms on the eye's lens. The lens is located behind the iris and pupil. Although cataracts may be related to the aging process, there also are other types of cataracts that are have other causes. These causes can include radiation, congenital and an injury, states the National Eye Institute. A main treatment for cataracts can be surgery to replace the lens with an artificial one.
