PixelOptics SuperVision Optimizes Your Sight
PixelOptics believes that their SuperVision system can improve anyone's sight to better than 20/20 vision. The US military agrees; the DoD has awarded them a $3.5 million grant to refine their technology.
According to PixelVision executive V.P. of R&D, Dr. Dwight Duston:
"Certain nonuniformities within the human eye are the cause of most vision deficiencies. Conventional aberrations, such as nearsightedness (myopia) and farsightedness (hyperopia), can be corrected with normal spectacle lenses to give 20/20 vision.
The spatial density of light receptors in the retina, however, is enough to allow human eyes to see better than 20/20, perhaps as well as 20/08. However, higher-order aberrations in the eye prevent us from attaining this "SuperVision."
PixelOptics's lenses dynamically alter the focus in ways not possible before. By adjusting the refractive index of an array of transparent pixels contained within the lens, it is possible to correct for the higher-order aberrations. This optimizes one's vision, in many cases, beyond how one sees today."

How does it work?
The operation of these spectacle lenses is based on electrical control of the refractive index of a 5-ėm-thick layer of nematic liquid crystal using a circular array of photolithographically defined transparent electrodes. It operates with high transmission, low voltage, fast response (<1 sec), diffraction efficiency (> 90%), small aberrations, and a power-failure-safe configuration.

Most of us are familiar with the "supervision" of the Six Million Dollar Man, who had a bionic (electronic-based) eye; this invention is really more a super-pair-of-glasses that will allow us to perfectly focus, allowing us to achieve the hightest possible resolution vision.
