  • To determine the diopter value, place a piece of paper with writing under the magnifier, move it away until it’s out of focus, and bring it back in until it just goes back in focus. Then measure the distance (in inches) from the center of the lens to the paper, and divide that distance into the number 40. The result is the diopter of the magnifier. The 25% Rule
  • Each diopter number increases the apparent size of a magnified object by 25%. As an example, if you want to view something twice as big as it is, you would need to increase it 100%, or four 25% increments. Each diopter will give you one 25% increment. Therefore, you would need a 4 diopter lens.
