Reduced lenses

Glasses or contact lenses that have less power than full correction.

Normalized

With the reduced lens method, 0.25 diopters less than full correction is a typical reduced lens power for normalized lenses.

Differentials

1.00 - 2.00 (1.50) diopters less than full correction is generally a useful reduced lens power for differentials worn in close-up activity.
