Home > Health Library > Eyeglass Prescriptions
Prescriptions for glasses have two main components: shape and power.
The shape of a lens determines the type of correction.
The power of a lens determines the amount of correction. It is specified in diopters. The higher the number of diopters, the more vision correction the lens provides.
