Special Memory Metal Eyeglasses
Nowadays, eyeglass frames can be made from many materials. They mainly include plastics, metals as well as unusual materials such wood, leather or even stone. Plastics used to produce eyeglass frames include zylonite, cellulose acetate propionate, nylon, CR-39, polycarbonate as well as high index variations. Factors that can be used to assess these materials contain hypo-allergenic, lightweight, strong, flexible, corrosion-resistant, as well as color options. Within the large category of metal frame eyeglasses, possible materials contain Monel, titanium, beta-titanium, beryllium, stainless steel, aluminum and some other alloys. In similar, the aforementioned factors are also widely used to compare one metal with another. Along with the pervasive availability of lens options, there are actually many styles of eyeglasses for customers to choose from. But it seems that scientists are still making restless efforts in developing more materials for different industries including the eyewear industry. This trend has been testified by the creation of new forms of plastics such as polycarbonate and high index ones. Furthermore, it can also get proof from the wide collection of alloys that are being used in many fields. Memory metal eyeglasses are a perfect example. (more…)
