Blood sugar control
Hypertension
Smoking
Alcohol
Pregnancy
Glaucoma

Open angle
chronic glaucoma
Peripheralvision loss
Closed angle
sudden onset “Sneak Thief of Sight”
Damage occurs to optic nerve
26
symptoms
Loss of vision, particularly side vision
Blurry or foggy vision
Difficulty adjusting to dark rooms
Rainbow-colored rings around lights
Remember, even without any warning signs you may still have glaucoma. Don’t wait for problems before getting a regular eye exam.
