Why Bono Wears Sunglasses
When people think of Bono from U2, they are likely to have an image of a man wearing sunglasses in their head. While musicians are known to wear sunglasses all the time, they usually do it for the ‘rock star’ look!
Last week, Bono disclosed on The Graham Norton Show there was a medical reason he always wore his sunglasses for all these years. When Graham Norton asked Bono if he ever removes his shades, he was given quite an unexpected answer. Bono explained, “This is a good place to explain to the people that I’ve had glaucoma for the last 20 years.” It is great he has shared his story as it will help more people become aware of what glaucoma is.
What is Glaucoma?
Glaucoma is a disease where the optic nerve at the back of the eye, which connects the eye to the brain, is progressively decaying. It is most commonly associated with raised fluid pressure inside the eye. The progressive decay of the optic nerve causes a gradual loss of peripheral vision, and if left untreated, the patient will eventually have severe irreversible vision loss and blindness, and a form of tunnel vision.
What Causes Glaucoma?
There are a number of different forms of glaucoma with individual unique causative factors. Many are related to structural changes within the eye that impede the outflow of the internal aqueous fluid leading to increased eye pressure. Glaucoma genes have been identified in recent studies, and there has been shown to be a 10 times greater risk if you have a direct relative with the condition. Patients with diabetes, cardiovascular disease and myopia are also more likely to be affected.
What about the Glare?
Glare can be a real problem for people with glaucoma. Whether it is from the sun or a bright indoor light, glare can reduce the brightness differences and impair contrast sensitivity. Tinted lenses can be used to lessen the effects of some of these problems.
The amount of light available can also present challenges. Most people who have glaucoma are very sensitive to excessive light, especially extreme sunlight. Moderately lit conditions can also pose a problem and usually require additional lighting.
Now that Bono has shared his story on why he has been wearing his shades for all these years, it has made people more aware of glaucoma.
