FlexVision – Eyeglasses that adjust to your eyesight, not the other way around

>"How It Works

It works through a new technology called Dual Lens. This lens system consists of

two thin, wave-shaped "plates" that slide over each other

(http://selfadjustingglasses.com/reviews/flexvision/en/int1j2...)

with a twist of the button on the side of the frame.

It enables you to self-adjust the power of the lens for each eye. Turn the dials to change the lens power at any time from -6 diopters of nearsightedness to +3 of farsightedness. This way you can address the problem of outdated and inaccurate spectacles."

PDS: Think of this as a tuner -- for optical distance...

A tuner in the above context -- is something that focuses something else in a certain way at a certain point -- in the above case, it's light rays -- but in theory (if made of the appropriate materials!) -- it could be any wavelength of the electromagnetic spectrum...

(Optical Distance / The Focusing Of Optical Waves Of Light -- for lack of better terminology -- is an "Inverse Square Law" AKA "Law Of The Squares" phenomena (or at least highly related!): https://en.wikipedia.org/wiki/Inverse-square_law)

It would be interesting to play with the above lens design -- but using different non-glass materials -- and experimenting with non-optical waves / wavelengths...

What would happen?

Anyway -- a highly interesting eyeglass design!

Being nearsighted, but getting older and needing a separate reading prescription, I would love adjustable glasses, but this is not it. I have to buy at least three pairs of glasses every time my prescription changes:

1. A pair with progressive lenses, for being out and about. I need the distance vision for driving, and the intermediate/near range for looking at instruments in the car, and for shopping.

2. A pair of reading glasses, for reading without eye fatigue.

3. A pair of computer glasses, which are similar to reading glasses, but "detuned" for the longer distance to the screen.

A workable design would be to have a pair of glasses with these three settings pre-programmed and selectable at the press of a button. Having to tune each lens individually for specific situations would be way more annoying hann dealing with different pairs of glasses.

Other than the two thumbnails, why are there no pictures of the glasses being worn?

Are you they not proud of how the glasses look, or are they very budget conscious (ie. Using stock photos, instead of commissioning product photos)?

This seems really good for the developing world, but seems like a recipe for a headache. Adjusting each eye independently everytime seems like a recipe for having inconsistent relative power between the lenses.

I've never found the adjustable diopter on camera viewfinders to be very usable, I imagine this would be the same.

Call me when these go up to -10 diopters

Probably very heavy and the dual lenses might lead to very annoying reflections and double images.

Why are we allowing scams on this site. Isn't there any check?
