The real reason Bono always wears sunglasses

Bono never seems to go anywhere without wearing his signature shades. Yet all this time, there was a specific, medical reason for this — one he finally told the public during a taping of BBC One’s Graham Norton Show. When asked if he ever removes his shades, the U2 frontman responded:

“This is a good place to explain to people that I’ve had glaucoma for the last 20 years. I have good treatments and am going to be fine.”

Glaucoma is a condition in which pressure on the eyeball can cause damage to the optic nerve, sometimes resulting in blindness if not properly treated. Those who suffer from the disease are often sensitive to light, and wear dark glasses to alleviate their symptoms.
