Bono

The U2 frontman’s trademark tinted spectacles are a protective medical tool, not an indoor style preference.

Bono revealed on The Graham Norton Show that he has spent over two decades battling glaucoma, a progressive condition that causes severe sensitivity to light and blinding camera flashes.

Brushing off any public self-pity, the rock legend candidly joked: "You're not going to get this out of your head now, and you will be saying, 'Ah, poor old blind Bono.'"
