What is a Cataract?
A cataract is the loss of transparency of the crystalline, a structure that is located inside the eye, behind the pupil, which works as a lens, and focuses images in the retina. This works in the same way as a camera lens that focuses the light on the film (retina).
Why does this Occur?
Most cataracts are formed when individuals get older, and it is another symptom of aging.
You should realize that the age when this occurs varies, and that it is frequent to have cataracts on both eyes. However, the evolution of one or the other eye differs, and the loss of visual acuity is slow and progressive.
There are other causes related to external attacks, traumas, general diseases (diabetes), ocular diseases, the use or abuse of medicines (corticosteroids), environmental causes, ultraviolet or infrared radiation, etc.
There is also a special type of cataract, which is called congenital cataract, which occurs when the individual is born and might be unnoticed, with a great risk regarding the development of future eyesight. To prevent an incorrect diagnosis and to detect any other potential ocular problem, every newborn should be examined by an ophthalmologist.
