Precautions for glasses
1, before matching, you should have a general understanding of the refractive index of lenses and know the approximate price of different lenses to avoid being cheated when recommending lenses.
2. The lens of1.74 is the most expensive and thinnest lens. It's normal for a picture frame to cost thousands of dollars. If myopia is not serious, you don't need such good lenses at all. The lens with 1.67 is already extravagant.
3. Try to choose a better spectacle frame. People with high myopia must choose glasses frames with small frames. Never choose a retro big frame or half frame to avoid peeling.
4. It is recommended not to choose frames with many edges and corners. If the frame breaks unexpectedly, it will be more difficult to choose a more suitable frame again.
