What's the difference between optical frames and normal frame?

The optical frame is used in optical products, but decorative glasses and fashion frames are not in this category. Optical glasses require even treatment of lens pressure, so the inner wall should be even and smooth. Optical glasses require high levels of ergonomics, lens angle, and so on. The optical frame material is more consistent with the structure of the human body. It is more comfortable to wear without side effects.


h3>Transparent Frames

Transparent frames: as for glasses for round faces, the transparent frames aren’t going away anytime soon. Whether clear or with a faint tint, these frames are almost invisible from a distance and make it easy to clearly see the soft features of a round face. So, if you need a pair of glasses for a round face, try the transparent or clear frames.

Full-rim glasses: round faces look best against strong angular lines, while full-rim glasses can enclose and balance these features. So, you can take the full-rim glasses into consideration when choosing round-face glasses.
