Diopter is a measure of the power of a [[lens]] (or mirror). It is equal to 1/[[focal length]] in meters. In EM we refer to the [[cm measurement]] to calculate diopters needed to correct [[refraction]] of the eye. If you can see 50cm clearly your diopters will be 1/0.5=2 diopters. | Diopter is a measure of the power of a [[lens]] (or mirror). It is equal to 1/[[focal length]] in meters.
