How to Choose Reading Glasses Diopters
The level of magnification in the lenses of reading glasses is called diopter strength. A very weak magnification would be found in reading glasses with a diopter strength of +.75 or +1.00. Off-the-shelf reading glasses sold in drug stores or elsewhere on the Internet are often offered in diopter strengths that start with 1.50, and with only a few options for stronger lenses.  We offer from 1.00 to 4.00 in many models.
Reading glasses come in half frames and full frames. Sometimes, frames fitting neither description are called three quarter frames.  Reading glasses come in diopters, or strengths from +1.00 to +4.00.  We also sell strong power readers in +4.50, +5.00 and +6.00.
