Glaucoma refers to a group of eye diseases that damage of your optic nerve. The optic nerve connects your eye with your brain. These signals become the images you see, and they are directional signals that tell your eye which way to look and where to focus. They even control involuntary signals like your automatic blinking.
The danger of glaucoma is that there are no warning signs or symptoms, which makes glaucoma the leading cause of irreversible blindness. When glaucoma does appear, it is usually too late to remedy and some vision loss has already occurred. Therefore, early detection is the best remedy, and this is achieved through regular and thorough eye exams.
You should have your eyes tested regularly for glaucoma. Doctors recommend patients under the age of 40 to have them checked every two to four years. From ages 40–54, you need a check-up every one to three years. From ages 55–64, you should get a test every year or two. If you’re over age 65, it’s recommended that you have your eyes tested for glaucoma every six to 12 months.
