Testing the Protection of Sunglasses by Means of UV/Vis Spectroscopy

Although sunglasses are a popular fashion accessory, they are vital to protect the eyes against harmful UV radiation. The shorter the radiation, the more harmful it is to human eyes and it is recommended by health professionals that sunglasses should filter radiation up to 400nm almost completely. In this application note, several sunglasses were tested for UV filtration using the SPECORD® 250 PLUS from Analytik Jena.
