First Claim
Patent Images
1. An ophthalmic lens for a user comprising:
- a progressive addition region, wherein said progressive addition region has an add power therein; and
a tunable dynamic optic in optical communication therewith having a tunable optical power when said tunable dynamic optic is tuned with the application of electrical energy, mechanical energy or force and where said optical power of said tunable dynamic optic when added to said add power of said progressive addition region is substantially equal to the user'"'"'s near distance add power vision correction.

Abstract
An ophthalmic lens is presented in which the lens includes a progressive addition legion and a dynamic optic. The dynamic optic and the progressive addition region are in optical communication. The progressive addition region has an add power which is less than a user'"'"'s neat viewing distance add power. The dynamic optic, when activated, provides the additional needed optical power for the wearer to see clearly at a near distance. This combination leads to the unexpected result that not only does the wearer have the ability to see clearly at intermediate and near distances, but the level of unwanted astigmatism, distortion, and vision compromise ale reduced significantly.
