Features
What could be more convenient than having one pair of lenses for all occasions. Nobody really wants to have to carry around two different pairs of spectacles at one time, having to switch as lighting conditions invariably adjust. Indoors, outdoors, sunshine, cloud, rain... People of all ages are constantly on the move and do not want to be restricted by their capacity to view the world around them. Lenses should adjust to suit the wearer's need and not the wearer making sacrifices. 1.56 index photochromic lens offers the freedom to forget one is wearing spectacles - thin, light and reliable, performing whatever the weather, whatever your activity.
