IMAGE PROCESSING USED TO ANALYZE THE LAYERED LENS STRUCTURE

Abstract

The lens is an optical element mounted in a frame of metal, plastic or other materials for the purpose of correcting and / or protecting the visual system. These medical devices (orthotics) are made of optic, polycarbonate, or plastic with refractive indices standardized (1.523 ophthalmic refractive index) or not ("strong glass" with refractive indices above 1.6). Glasses for correction or protection, general use or for professional activities, for private use or sports, cultural or dedicated to different fields require special materials and technologies. The first part of the paper presents some considerations regarding the construction of glasses and the use of specific materials. In the second part of the paper, the stages of analysis of some variants of glasses used for different sports and the image processing of some lens and accessories material features are presented. In the final part of the paper are presented the results and the conclusions obtained.
