The end of glasses?

Eyeglasses work by refocusing light onto the retina, the light-sensitive tissue in the back of the eye responsible for transforming photons of light into signals the brain can turn into images. Unfortunately, the bending of the light isn’t perfect, and the eye ends up elongating and compensating even more to make up for the difference, exacerbating the Myopia. “The experimental lenses use different focal powers within a single lens: either alternating focal powers across the lens, or confined to the outer edge,” reports Phys.org.
