Polarised sunglasses are particularly popular with fisherman and skiers who have to deal with strong glare from surrounding water and snow. Reflected UV rays present an equally dangerous obstacle for protecting our eyes against the sun. Of course, anybody who spends a great deal of time outdoors will find these types of glasses useful. As a result, they’ve become extremely popular and part of mainstream fashion.
They can also be very useful when driving too, reducing glare caused by reflections from hoods, windows and mirrors, although wearing them does reduce visibility off of LCD screens on GPS devices and satnavs. Individuals who are sensitive to light, for example those who suffer from light sensitive epilepsy, or post-cataract patients, may choose to wear them indoors.
Megastar and U2 front man Bono is known for almost always wearing dark shades, but few people may know he wears them to protect his eyes from the intense snaps of paparazzi cameras.
