Eyeglass frame is an indispensible part of a pair of eyeglasses or sunglasses. The increasing number of people using prescription eyeglasses and sunglasses drives eyewear manufacturers to work out new products. For designers who focus on prescription eyeglasses, the frame is nearly the sole part that is under control. Using unusual or even unused frame materials has been considered as a good idea. Many brands release eyeglasses in cute, novelty shapes. Some others develop eyewear models made of colored frames. Frame structure is also under consideration by eyewear design houses. This is definitely a noticeable factor. And until now, there are basically three forms taking use of specific frame structures. Rimmed eyeglasses are the most traditional style, while semi-rimless and rimless spectacles mark a revolution in the eyewear history.
Rimmed glasses can also be called full-frame eyeglasses or full-rimmed glasses. With this explanation, it is clear that these are eyewear products that have a complete frame, which encircles the whole part of each lens. It is necessary to compare rimmed eyeglasses with other two basic forms, in terms of structural differences. As the name suggests, semi-rimless glasses have only a half frame, which only partially covers the lenses. In most cases, only the top portion is encircled. Compared with rimmed and semi-rimmed styles, rimless glasses go to an extreme that they have no frame around the lenses. The bridge and temples are mounted directly onto the lenses. In fact, the structural differences between rimmed and other two styles are quite obvious.
Exterior features of rimmed glasses are mainly determined by the frame structure, so do the other two styles. Rimmed eyeglasses have been around for several centuries, while semi-rimless and rimless spectacles emerged in 1930s and 1940s. Products with a longest history always represent the most conservative design concept. This is absolutely applicable to the eyewear industry. Full-frame eyeglasses are the most traditional and conservative. But they are the best choice for people who want to get a formal look, etc businessmen. The other two forms are modern and fashion-oriented, and they are widely welcome among young and middle-age ladies and boys.
