Eyeglass Basics

Other characteristics of frame materials to consider are the weight or flexibility of the material as well as the price. Many designers also use wood, bone or precious metals to adorn frames and add an extra .

Hinges and nosepads also play an important role in durability and comfort of your frames. Children in particular can benefit from spring hinges and nosepads which can keep the frames from slipping off. Rimless or semi-rimless glasses are also an option for those that durability is not a primary concern.

Frame size is a very important factor in frame selection. Frames should fit well and not slip off the nose or be too tight and press against the temples or the sides of the nose.

More and more top fashion design brands are coming out with designer eyewear collections to suit every taste and style. Frames come in all colors, sizes and shapes so the choices are endless in finding a frame that suits your personal style and looks good with your face shape and coloring.
