Whether it's school or work, there are more and more nearsighted friends around us now. But every nearsighted student raised his glasses and shouted "headache.". It is understandable that lenses are expensive, after all, there is a technical bonus, but some ordinary lens frames in stores are still very expensive after being discounted, which is really a headache. However, in the face of glasses online affordable frames, it is also difficult to choose! Which one is suitable for me? One of the biggest challenges in buying frames glasses online is what size you want.
Take a look at the size of the original glasses, which are generally measured inside the lens legs. For example, "52 17-140" refers to the frame width: of 52mm, nose bridge width: of 17mm, and lens leg length: of 140mm. If the original mirror frame size is appropriate, try to choose a similar size, with a difference of 1-2 mm having no impact (same material); If the above data have been worn away, it is recommended that you use a ruler to measure the comfortable glasses you previously wore and record the overall width and inner width of the frames. The inner width of the lens frame can be adjusted by plus or minus 5mm according to the actual wear tightness.
But are we most concerned about these? My concern about glasses online must be price performance, affordable fashion, and comprehensive coverage of popular styles on the market. Students who wear glasses every day really understand how important it is to have a lightweight frame.
