A recent study estimates more than 82,000 people in the state have the eye disease.
That's up 35 percent in 10 years.
Prevent Blindness Georgia is joining with other leading vision and eye health groups to promote January as National Glaucoma Awareness Month.
Eye doctors say a big reason for the increase in cases is better detection.
"We have a lot better instrumentation today then we once did and there is a lot better understanding on the dynamics of the condition as well. So that when a person has there eyes evaluated and they have a thorough comprehensive eye evaluation, we are looking at things other than just the pressure within the eye," said Optometrist Dr. Ron Bannister.
The study says half the people who have glaucoma are not aware of it.
