There are three main types of reading glasses on the market, namely single vision, double vision and progressive multifocal. Single vision lenses can only be used to see near, and you need to take off your glasses when you see far. Bifocals mean that the upper half of the lens is used to see far, and the lower half of the lens is used to see near, but this kind of reading glasses has a jumping phenomenon, and the appearance is not beautiful. Progressive multifocal lenses can meet the needs of different distances in the far, middle and near, and the appearance is also very good.
