When choosing a spectacle frame, in addition to price and aesthetics, it is important to pay special attention to matching the size of the frame with the pupil distance as much as possible, as it directly affects the internal optical quality and wearing comfort of the glasses.
The identification of mirror frame quality can mainly consider the following:
1. Mirror frames with good elasticity generally have better quality.
2. The mirror frame with a smooth and shiny coating has good quality.
3. The quality of mirror frames made of smooth, small, and uniform materials is good.
4. It is better to assemble all parts tightly.
5. The size and shape of the mirror ring must be exactly the same, and the bridge of the nose must be symmetrical.
