Do auto focus glasses really work?

How do self adjusting glasses work?
Put simply, changing the physical shape of the lens by pumping the silicone fluid in or out alters its refractive power – the extent to which a lens bends light as it passes through the eye – allowing the wearer to correct their own refractive error.

Their glasses take a cue from how eye lenses work; the autofocal lenses are filled with fluid that expand and contract as your field of vision shifts. As you’d expect, there are eye-tracking sensors to figure out what you’re looking at.
What is self adjusting glasses?
A lens in the front part of the frame adjusts to correct myopia, or nearsightedness. To correct close up vision, you move a slider along the frame’s bridge to push around the fluid and alter the shape of the lens. The eyewear’s round shape mimics the shape of the eye, Kurtin said, which further sharpens vision.
Do glasses change focal length?
Glasses are cut to change the focal length of the light entering the eye so it hits the focal point properly and the wearer can see without blurring. Convex lenses correct nearsightedness by refracting the light toward the bottom and the top of the lens so it pushes the light farther back into the retina.
