The 11 pages that link to Diopter, each with the reason it gives.

• Focal lengthRelated: It provides the common unit for expressing focal length’s reciprocal in vision and lens prescriptions.

• Refractive errorNarrower topic: Prescriptions quantify refractive correction in diopters.

• HyperopiaRelated: Hyperopia is measured in positive diopters, indicating that additional converging power is needed.

• MyopiaRelated: A myopia prescription uses negative diopters to specify the diverging power needed for distance correction.

• EyeglassesRelated: Eyeglass prescriptions use diopters to specify lens power.

• AccommodationNarrower topic: Accommodation is quantified as a change in the eye’s optical power, measured in diopters.

• PresbyopiaRelated: Near-vision prescriptions quantify the extra optical power presbyopia requires.

• EyepieceRelated: Eyepiece focusing and prescription adjustments are often specified in diopters.

• Magnifying glassRelated: Magnifier strength is often specified in diopters rather than focal length.

• Allvar GullstrandRelated: The unit expresses the refractive powers central to Gullstrand’s analyses.

• LoupeRelated: Diopters quantify the optical power commonly marked on magnifying lenses.
