Glaucoma is an eye disease that damages your eye's optic nerve. Sometimes resulting in permanent vision loss, it's one of the leading causes of blindness in adults over the age of 40. With glaucoma, either too much fluid is produced or it doesn't drain efficiently. The fluid builds up and causes pressure to rise inside the eye, which leads to optic nerve damage. However, lowering eye pressure can help you keep your eyesight.
