Diopter

A diopter is one whole number on a prescription. The number of diopters on your prescription represents how much correction is needed to normalize your vision. The more myopic or hyperopic you are, the higher your prescription will be represented in diopters. Myopic, or nearsighted prescriptions are normally indicated by negative numbers, such as -4.75. Hyperopic, or farsighted prescriptions are normally indicated by postitive numbers, such as +4.75.
