UV radiation is
absorbed by ordinary glass Hence, one cannot get tanned or sunburn
through glass windows Welders wear special glass goggles or face masks with glass windows
to protect their eyes from large amount of UV produced by welding arcs Due to its  shorter wavelengths, UV radiations  can be focussed into very
narrow beams for high precision applications such as  LASIK (Laser-
assisted in situ keratomileusis) eye surgery
