Some people may find it difficult to know clearly the situation in the current eyeglasses spectacles market. In this article, we try to give the guidelines on some of the most important aspects of eyewear. Frame material deserves our first consideration. The conclusive words are that eyeglass frame material market has been greatly diversified, compared with the situation one or two decades ago. Even if any workable materials are possible to make eyeglass frames, the most commonly used materials are plastics and metals. The current situation in this world is that traditional plastics and metals have been nearly abandoned by most eyewear manufacturers. They are replaced by new plastics and various types of metals with superior attributes. Stainless steel, titanium and memory metal are some of the most popular.

Advances can also be seen in the eyeglass lens industry. Modern eyeglasses spectacles can take advantage of advanced lens materials and lots of assisting coatings. The most advanced and popular lens materials include high-index plastics and polycarbonate. Taking use of these basic materials, lens technologies have made available many advanced forms of lenses, such as aspheric lenses, wavefront technology lenses and photochromic lenses as well as polarized lenses. Furthermore, users can also gain additional help from some assisting lens coatings that are widely applied, like anti-reflective coating, scratch-resistant coating and anti-fog coating.

Another important point of the current eyewear market is the availability of frame styles, which determine the wearer’s general appearance. Eyeglasses spectacles currently come in mainly full-frame, semi-rimless and rimless styles. Other decorative elements contain multi-colored inlays, composite materials, designer emblems and insets of precious stones. Some have become quite stylish as fashion accessories, especially those rimless pairs.

The changes that have been made in lens functionality are also worth mentioning. The basic point is that those single-vision lenses are to some extent losing popularity. More and more people especially presbyopic patients turn to multifocal lenses, like bifocals, trifocals, and progressive lenses. Glasses made of these lenses can bring more visual help.
