When choosing a spectacle frame, in addition to price and aesthetics as the standard, special attention should be paid to the size of the frame selected to match the pupil distance as much as possible, because it directly affects the inherent optical quality and wearing comfort of the glasses.
The identification of the quality of the frame can mainly consider the following:
1. Frames with good elasticity are generally of better quality.
2. The quality of the frame with smooth and shiny coating is better.
3. The quality of the frame with smooth, small and uniform solder joints is better.
4. It is better if the parts are assembled closely.
5. The size and shape of the left and right mirror circles must be exactly the same, and the bridge of the nose is symmetrical.
