Blind people wear sunglasses to help reduce the damage that can come from ultraviolet rays or to help them hide their eye deformity, according to the BBC and Prevention. Some blind people have eye deformities, which can be unsightly, facilitating the need to cover their with sunglasses.
There are many famous figures who have worn sunglasses outdoors and indoors due to their blindness including Stevie Wonder and Ray Charles says the BBC. Those with dry eye conditions also benefit from wearing sunglasses.
Even though a person is blind, the eyes can still be damaged and those with partial sight can further damage their eyes by letting UV rays touch the eyes. Sunglasses help protect what little sight may be left says Prevention.
The BBC reports that other people who are not blind but who have a photophobic condition or tendency, meaning that they are extremely sensitive to the light, can benefit from wearing sunglasses indoors. The sunglasses shield the person from strong light that can trigger uncomfortable migraines.
It is not just blind people that wear sunglasses indoors. There are large numbers of celebrities who also keep their sunglasses on when indoors. These celebrities include people, such as Victoria Beckham, Karl Lagerfeld, Anna Wintour and Lady Gaga, says the BBC.
