What term is used for a unit of measurement for ophthalmic prism?

Antireflection
34mm
Diopters
Colmascope

The correct answer is: Diopters

Diopters are the unit of measurement for ophthalmic prism, while the other options are not related to this specific measurement. Antireflection is a coating used to reduce glare on lenses, 34mm is a measurement of lens diameter, and Colmascope is a medical instrument used for analyzing the eye. These options are not typically used as units of measurement for ophthalmic prism. Therefore, Option C is the best choice for this question.
