“More than 2.7 million Americans over 40 have glaucoma, but only half are aware of it, according to the American Academy of Ophthalmology. The disease is one of the world’s leading cause of blindness. Particularly at risk: People over the age of 40. The Glaucoma Research Foundation reports that you’re six times more likely to get glaucoma if you’re over 60. Also more vulnerable than average are those with a family history of the disease, African Americans, Hispanics, people with diabetes and smokers.”
