The cataract looks like a hazy film on the lens of the eye and is diagnosed by an ophthalmologist during the examination.

glaucoma - This is a disease of the eyes, which is characterized by an increase in intraocular pressure and optic nerve damage. The visual acuity thus decreases until full blindness. Often, the disease develops in people older than 50 years, but there are cases of congenital and juvenile glaucoma.
