Patent number: 7988286Abstract: An ophthalmic lens is presented in which the lens includes a progressive addition region 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 near 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 are reduced significantly.Type: GrantFiled: September 18, 2009Date of Patent: August 2, 2011Assignee: E-Vision LLCInventors: Ronald D.

Patent number: 7619809Abstract: A mirror assembly including an active lens and a reflective surface. The mirror assembly may change its refractive index when a voltage is applied to the active lens, thereby changing the field of view in the lens. Exemplary applications include a blind spot system in a motor vehicle, in which, upon sensing another vehicle in a driver's blind spot, the mirror assembly changes the driver's field of view to include the blind spot. Additional applications include a magnifying mirror for shaving or applying cosmetics.Type: GrantFiled: July 26, 2006Date of Patent: November 17, 2009Assignee: E-Vision, LLCInventors: Ronald D.

Patent number: 7533993Abstract: An electro-active phoropter and a method of using the electro-active phoropter to measure a patient's vision prescription is disclosed. The electro-active phoropter includes a series of individually addressable electro-active lenses. The lenses have either a positive or negative optical power when an electrical potential is applied across the lens and a neutral optical power when no electrical potential is applied across the lens. Each lens provides an optical power that is part of a net optical power of the series of lenses when a patient views through the phoropter. The optical power of the phoropter can be incrementally adjusted by changing the distribution of the electrical potential across the different lenses of the series to provide increasing or decreasing optical power until a patient achieves a desired level of clarity and a vision prescription has been determined.Type: GrantFiled: December 31, 2007Date of Patent: May 19, 2009Assignee: E-Vision, LLCInventors: Ronald D.

Patent number: 7490936Abstract: A lens system and optical devices that provide enhanced vision correction are disclosed. The lens system includes an electro-active layer that provides correction of at least one higher order aberration.
