Experts predict that the number of vision loss patients increases due to the increase in the risk of diabetes and another serious disease.

However, there are many causes of sudden and gradual vision loss, some of them are described below.

That causes vision loss and ultimately may lead to blindness. Open-angle glaucoma, or (OAG) is the most common type of glaucoma prevailing in the U.S.
