The basic structure of glasses includes lenses and frames. Lens is the core part of glasses, which uses optical principles to correct vision problems by refracting light. Whether it's nearsightedness, hyperopia, astigmatism, or presbyopia, lenses can all play their unique corrective function, making our vision clearer again. And the frame carries the lenses, it not only needs to be beautiful and elegant, but also comfortable and durable, ensuring that we can wear glasses for a long time without feeling tired.
