Shapes of eyeglasses frames
Since there are many aspects that should be assessed, it is can hardly be easy to get an appropriate pair of eyeglasses. Two most basic aspects are eyeglass frame and lenses. Evaluating eyeglass lenses, there are lens materials, visual correction type, lens thickness as well as other factors. When it comes to cosmetic spectacles, it is always still necessary to a choose lens color. Furthermore, some opticians or eye care practitioners would recommend special lens coatings such as anti-reflective coating, scratch-resistant coating and so on. With detailed explanation by the doctor, the final decision often depends on the customer. The other part of a pair of eyeglasses is the frame. Actually, eyeglasses frames also have different types. Frame materials such as metal and plastic can divide those frames into main categories. And in a further step, there can be several variations within each main category. Eyeglasses frames can also be grouped depending on structural differences. For instance, there are frames with integrated nose pads and the others with flexible or adjustable nose pads.
Those are not all the ways to classify eyeglass frames. People with certain experience of choosing eyeglasses would know that there are different eyeglass frame shapes. But most of them may have only known the obvious differences between large frames and those small ones. In some cases, more experienced eyeglass users may have heard of eyeglasses frames shapes such as round and rectangular. In fact, the shapes of eyeglass frames are designed according to basic face shapes of human beings. In general, there are mainly six types of face shapes, namely, round, oval, oblong, square, base-down triangle and base-up triangle. Face shapes of most individuals can be fitted into one of these basic six types. In fact, these basic face shapes are listed by many online eyewear stores. They provide model images for customers to try on their favorite eyeglasses virtually.
Choosing eyeglasses frames should necessarily take personal face shape into account. A complementary pair of eyeglasses will enhance the natural beauty of the wear’s face. In an opposite case, disappointing effects may occur. Round and oval faces usually have few angles, so that a rectangular shaped frame is preferable. People with either round or oval face shape are encouraged to wear eyeglasses that can make their faces thinner and longer. Dissimilarly, oblong and square faces will comply with round-like eyeglass frames. Those obvious face angles should never be enhanced. The last two face shapes including base-down and base-up triangles also require specific frames. In general, base-down faces need a frame adding width to the upper face, and base-up faces require frames wider at the bottom.

Frames of this type are light in weight, gloss in appearance, and anti-irritation in performance, whereas they are easy to be cracked.
Metal eyeglasses frames are usually made from metal materials and alloys, among which copper alloy is applied most often as substrate material. And then surfacing work is made, which is accomplished by plating with gold, silver or chrome. Different plating procedures may contribute to different products, some of which are colorfast, while some are not. Besides, some frames are made from pure titanium and memory alloy. In general, metal frames are famous for their firmness, lightweight, good-looking appearances and novel styles.
Frames with mixed materials are usually cranked out by plastic and metal. Some are designed to wrap plastic up by metal, or vice versa; some are designed to be with different materials in different parts, for example frame front made from plastic while frame temples made from metal, or vice versa.
