Glaucoma is an eye disease that causes progressive and irreversible loss of eyesight.
The condition arises when the optic nerve that takes the message from the eye to the brain is destroyed as a result of high pressures in the eye.
Health experts have warned that even though everyone is at risk of getting glaucoma, some people are at higher risk of getting the disease.
They include people who are aged 35 years and above, those with a history of glaucoma in their family and those with diabetes mellitus.
The condition has no symptoms in the beginning until much later when there is marked loss of eyesight.
Some of the symptoms of glaucoma include blurred or distorted vision, frequent change of reading glasses and headache.
