Abstract
According to the invention, in order to visualize the ultraviolet radiation reflection power of a glasses lens (), a face of said lens is exposed to an ultraviolet radiation in order to reflect a portion of said radiation. The portion of the reflected radiation then activates a developer surface () having a visual appearance that changes under the influence of the received ultraviolet radiation. The developer surface is watched in real time by an observer (). Such a visualization is particularly quick, simple and demonstrative, and can be used in an optician's shop to help a client chose a glasses lens.
