Fitting eyewear on young faces requires patience and knowledge because children’s facial features are still developing and -- depending on the age -- some 
kids can’t express concerns about poor fit. Bettner Vision recommends specific types of frames and designs based on your child’s age and development.
Bettner Vision carries many frame designs that appeal to children and youth to ensure a proper fit. Special bridging between lenses ensures proper fitting over the nose for comfort and safety. 
Spring-hinge temples on some eyewear frames help maintain proper fit to keep glasses from slipping as well as space for rough handling. The spring hinges allow frames to bend outward without breaking.
Well-fitted plastic frames work well, but metal frames offer rocking pad arms that can be angled for individual adjustment and a more contouring and comfortable fit.
