How Long does A Pair of Glasses Really Last?

First of all, the glasses get along with us every day, and the frames are prone to loosen or deform after using them for a long time. Secondly, the lenses are prone to yellowing, scratches, cracks and other wear and tear. Finally, as the diopters of myopia grows, the old glasses cannot properly correct the current vision.
The ensuing effects are numerous. Eyewear frame deformation, which can affect wearing comfort. Worn lenses make you difficult to see clearly due to light dispersion, causing vision loss.
