New Wearer-Correctable Eyeglasses

"How TruFocals Work

As simple as TruFocals are to use, their technology is very sophisticated.

 

Each "lens" is actually a set of two lenses, one flexible and one firm. The flexible lens (near the eye) has a transparent distensible membrane attached to a clear rigid surface. The pocket between them holds a small quantity of crystal clear fluid.

 

As you move the slider on the bridge, it pushes the fluid and alters the shape of the flexible lens. Changing the shape changes the correction. This mimics the way the lenses in your eyes used to perform when you were younger.

 

This allows you to choose the exact correction that works best for you at any distance and under any lighting conditions. The result: clear, undistorted vision over a wide field of view: no zones, no lines."

I would love to check these out. I got a new pair of no line bi-focals in the spring and can't seem to get used to them. Went back to my old pair.

An advancement of this correctable lens concept is either in the works or available now.

 

The correction is not made mechanically.

 

The advanced lenses automatically correct ("automatic bifocals") based on where the wearer is looking through them.

 

Touching the frame on the side also causes another lens change/correction. (Darkening/lightening of the lens?)
