Lens users have 3 problems. First, they cant easily recognize front and back of lens. Second, lens is very small and transparent. If they lose their lens, then they are embarrassed. Third, users cant recognize 'Right' and 'Left' easily.
RLens can solve this problem by using chameleon paint.
The diagrams on RLens are changing when temperaure is closing to human body temperature. When people dont wear the RLens, the printings are very clear to see, so it is easy to find out even if users dorp it on the ground. Another benefit of RLens is that taking shorter time to figure out whether it is right or left, and front or back.
