Frequently Asked Questions (FAQs)

1. What are lens diopters?

diopter, in optics, unit of magnifying power of a lens or lens system. Because the power of a lens is proportional to unity (one) divided by the focal length (see lens), the power of a lens in diopters is numerically equal to 1 m divided by the focal length in metres.

2. What does a +2 diopter do?

Where it gets slightly confusing is that higher-power diopters reduce the maximum focus distance — so a +2 diopter on a lens set at infinity will reduce the maximum focus to 1⁄2 meter (1.64'), a +3 diopter will reduce the focus to 1⁄3 of a meter (13.12"), and so forth.

3. What diopter lens do I need?

Measure the distance in meters between your lens and the ground, at which you get the best focus. Divide 1 m by that distance, and that will give you the diopter value of your lens. For instance if your lens focuses the sun at 0.5 m, you have a +2 diopter lens.

4. Which is better 3 diopter or 5 diopter?

Objects viewed under a 3 diopter lens will appear 175% bigger than normal. A 5-diopter lens = 5/4 + 1... or 1.25 + 1 = 2.25x. Objects viewed under a 5 diopter lens will appear 225% bigger than normal.
