Progressive addition lenses compound the issue inasmuch as they use asymmetric curves to correct for distance, intermediate, and near vision, creating physical distortions on the lens surface. Free-form, digitally surfaced, cut-to-polish, and direct-to-surface are but some of the terms being used to spell it out the same group of lenses.

- Sometimes, higher-order aberrations make a difference your vision, even though your prescription eyeglasses fully correct your nearsightedness, farsightedness and/or astigmatism.
The DRP and Near Reference Point permit you to position the lens to learn the refractive power for distance and near viewing. The NRP must clearly fall within the eyewire once the centration chart is used, and the lens blank must completely fill the eyewire. The lens designer must cause the digital lathe to create curvatures that yield the prescription shown by the test lenses, even though eyewear lenses are tilted and turned. In other words, the lenses “as worn” must supply the power “as the patient tested.” As worn is another term for individualized. One of the most confusing reasons for having digital technology is the terminology.
