The important thing to remember when choosing reading glasses is, the higher the number, the greater the power of the lenses. Typically, one of the following numbers will be displayed: Both lenses are the same power, which is indicated by a permanent marking on the inside of the frame or with a removable sticker on the lens.

The strength of all reading glasses is measured in dioptre, with units increasing by 0.25 dioptre depending on the power of the lens.
