When we think of U2’s lead singer, Bono, we immediately think of his signature glasses. Bono recently revealed that his glasses are not cosmetic but are necessary because of his glaucoma. Glaucoma, a disease that damages the optic nerve, can cause hazy vision and the appearance of halos around lights. Bono explained to the BBC’s “Graham Norton Show” that “I have good treatments and I am going to be fine.” Even though he had excellent vision 20 years ago, Bono said that he noticed that objects and light were accompanied by haziness and rings and it was “not from anything exotic” (Source: CNN).
Glaucoma can affect anyone
Bono’s story is not unique. Glaucoma is one of the leading causes of blindness and is often referred to as the “sneak thief of sight” because it can progress without symptoms or pain. It is important that you know your individual risk for glaucoma.
You are at increased risk for glaucoma if you:
- Are over 40
- Are not Caucasian
- Have diabetes
- Use corticosteroids
- Have a family history of glaucoma
- Have an eye injury or an eye tumor
Regular comprehensive eye exams can help prevent glaucoma. There are several tests within the comprehensive eye exam can help diagnose glaucoma:
- A simple pressure check using a procedure called tonometry can measure intraocular pressure.
- Glaucoma can sometimes affect peripheral vision, so a visual field test can assess peripheral vision.
- A corneal thickness test can indicate intraocular pressure.
- Examining the angle where the cornea meets the iris can indicate open vs. closed angle glaucoma.
- Your doctor can even view the optic nerve by looking at the back of the eye through the pupil.
