#2 I'm waiting for it to make it Pearle Vision Centers with the See Through Clothes Radar option.

#3 Since the correction is dynamic, the lens should also be able to adjust focus for distance. Include a range finder and the glasses should be able to compensate for presbyopia.

Another technological solution would be direct laser scanning onto the retina. By reflecting laser light off the retina back to the laser source, the optical distortion can be measured. The laser scanning could then be adjusted to eliminate that distortion. Any optical system, including infrared, telescopic, or microscopic, could provide the optical imput to the laser scanning system.

#4 YES!
I have been waiting to see this technology developed.
Anonymous5032 - the technique you mentioned is involved.
What Supervision is can be stated this simply.
1) Lasik without cutting a flap and using lasers transparent to the material that makes up the flap but not the next layer.
2) Where a typical lasik treatment involves less that 20 or 30 bursts this involves thousands or tens of thousands of microbursts
3) It involves a feedback view of the eye and retnia after each burst so near perfect corrections can be made.
4) with this technique you should be able to recognize somebody on the torch of the statue of liberty from either shore!
5) Pixel comes into the name as it is such high resolution that the brain might well receive a pixelated view.


When I had my Lasik I was at 20/15-10 now I am 20/20 but as the laser burst creates planes instead of perfectly optically smooth surfaces I sometimes need to slightly adjust my head for a good view. With this method you would not have that kind of artifact.

#7 3dc, what you describe sounds very interesting. My own sight would greatly benefit from such an operation. However, this text from the linked article describes a different technology:

“Pixel'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."

Bill Kokonaski, Chief Technology Officer of Pixel, noted: "Higher-order aberrations of the human eye are dynamic, not static. Conventional refractive error such as myopia (nearsighted), hyperopia (farsighted) and regular astigmatism are static. However, higher-order aberrations change depending upon many factors, including the environment. Pixel's patented technology allows for a dynamic solution to a dynamic problem.”

This is basically how some modern telescopes function. The reflective surface is made of many small mirrors whose surfaces can be dynamically changed to compensate for atmospheric distortion. A laser is aimed in direction of the target object. Laser light reflects off atmospheric layers and is distorted by atmospheric variations. The mirrors can be adjusted to compensate for the measured atmospheric distortions.

I expect these lens work in a similar manner except they compensate for dynamic changes in the eye lens and structure.
