Every time we go out of our house, regardless of the time of year
and weather, we are always exposed to the harmful rays of the
ultraviolet or UV light coming from the sun. The ultraviolet light is
naturally invisible to the naked eye and we may not realize it that we
are continually exposing ourselves under it. Old people, adults, and
even children are required to wear the right pair of sunglasses to
protect the eyes from the harmful UV rays as they spend time outdoors
during daytime.
