There are also many breakthroughs in the technology and application materials of lens frames. Glasses with memory alloy frames can maintain their shape, and will not break even if they are bent, so that the glasses have a longer life and avoid the inconvenience caused by the broken frames. Adding springs to the hinge of the frame arm also makes the glasses more durable.

Glasses are made up of lenses and frames, which are used to improve vision, protect eyes or for decorative purposes. Glasses can correct a variety of vision problems, including myopia, hyperopia, astigmatism, presbyopia, strabismus or amblyopia.
