Literally clear. Joe Katzman reports that electro-active prescription lenses for eyeglasses have been invented.

New firm PixelOptics of Roanoke, VA has announced that it will receive $3.5 million from the Defense Department to develop “SuperVision,” a technology that may improve the vision of US soldiers beyond 20/20 via electro-active prescription lenses. The technology uses sensors and electro-active transparent material to alter the index of refraction of the lens dynamically, but without any moving parts.

This provides a number of performance advantages, allowing the wearer to instantly achieve optimal vision no matter where they look (far, near, or in-between). In addition, lenses based on this technology show promise for significantly reducing momentary blurring caused by head tilt and movement, as well as distortion associated with conventional state of the art bifocals and progressive addition lenses.

Joe reports that because of the technology of the lenses, it may actually be possible to improve 20/20 vision to better than that, “perhaps as well as 20/08.”

When I was a young fella, an optometrist actually measured my vision at 20/10. Alas, those days are long gone."
