Among the numerous options of eyeglasses, a customer may have difficulty in selecting a personal-suitable one. Both eyeglass lenses and frames have many types according to styles and materials. It is always necessary to differentiate metal frames from plastic frames, and compare glass lenses with plastic lenses. While eyeglass lenses are closely related with comfort vision, eyeglass frames are more closely associated with one’s appearance. Choosing an appropriate pair of eyeglass frame is essential to enhance the wearer’s natural beauty and express personality. There are some factors to be evaluated associated with a frame. Frame materials have been emphasized for many years. Nowadays, even metal frames made from titanium, stainless steel and memory metal can be lightweight and strong. These advancements have made frame materials less decisive in showing good look. However, there are some other factors that are determinative when customers try to choose individuals eyeglass frames. Simple questions such as who need round eyeglass frames and who need those rectangular ones are actually commonly considered by the public.

Frame shape is really one of the most important factors to be assessed. As a basic rule, the frame shape should contrast with the wearer’s face shape. With this criterion, it is easy to answer the discussed question in the last paragraph. There are generally two groups of individuals who should choose round eyeglass frames. The first group is people with a square face, which means they have a strong jaw line and a broad forehead, plus the width and length are in the same proportions. The other group contains individuals with an oblong face, which has a long straight cheek line and sometimes a longish nose. Both of these two groups have obvious facial lines or angles. According to the rule stated before, it is necessary to offset such obvious lines and angles. In this sense, round eyeglass frames or similar oval frames are the right choice. Based on the same rule, those individuals with oval or round faces should choose rectangular eyeglass frames.

In fact, frame shape is not the only factor associated with personal appearance. There are also decisive elements including frame size and frame color. Considering the first factor, the frame size should be in scale with the wearer’s face size. And the frame color should repeat the user’s natural coloring. Both of these additional factors are as equal important as frame shape. Round eyeglass frames should also be given a proper size and color.
