Adlens has announced the European launch of Adlens Select, an eyewear solution which is supposed to help the people frustrated by their changing eyesight. Adlens Select features an adjustable dioptre range from -4D to +5D. The eyewear lenses can be continuously adjusted for near, intermediate and distance vision at the turn of a small dial. Long-sighted customers can see and read even finer detail, says the company. Adlens Select will be available in black, crystal, chestnut, blue, and plum colored frames. The introduction of Adlens Select in Europe follows the successful launch of a similar product in Japan, which got an extremely positive response from customers, according to Adlens.
