Brazil scientists devise sunglasses UV protection checkpoint – BBC TV report

BBC World News – Health Check

SÃO CARLOS – Scientists at the University of São Paulo have devised a new easy-to-use kiosk checkpoint that allows passers-by to check the UV (ultraviolet) protection of their sunglasses.

The team, headed by Professor Liliane Ventura, found that most sunglasses do match the protection advertised, and are now studying whether sunglasses lose their UV protection over time.
