How to prevent glaucoma?

There is no prevention for glaucoma but it is treatable. Your best line of prevention is to get your eyes tested regularly and have your eye pressure checked.

Smoke pot.

Beta carotene mostly.

Carrots and lots and lots of water, being that is predominately what they are made of and use to function properly.

Everyone is at risk for glaucoma..from infancy to old age. They used to think it was intraocular pressure but more factors are at play here....diabetes, injury, old age, ethnicity and other diseases..
You can slow down the agressiveness of the disease but it will eventually cause blindness.
One eye doctor recommended Centrum Silver Vitamins to keep my eyes in good health.
