Generally, reading glasses refer to glasses designed to focus on close-up objects that have become difficult to see due to presbyopia. While they provide clear vision up close, distant objects appear blurry, so you need to take them off except when looking at something nearby. For those who want to see various distances with a single pair of glasses or want to avoid repeatedly putting on and taking off their glasses, "bifocals" are recommended for presbyopia. Bifocals are glasses equipped with lenses that can focus on a wide range of distances, such as near, far, and intermediate. By moving your gaze, you can focus on what you want to see. What is the difference between "magnifying glasses" and "reading glasses"? Similar to reading glasses, there are "magnifying glasses (glasses-type magnifiers)," but these are for magnifying close-up objects and are different from reading glasses. Magnifying glasses do not have a focusing function, so using them for extended periods can strain the eyes. When using magnifying glasses, it is recommended to use them in conjunction with glasses.
