You needn’t be an “early adopter” (a person who embraces new technology before most other people do) in order to appreciate the latest advance in eyeglasses. The electronic eyeglasses known as emPower! glasses contain batteries, microchips, and liquid crystal lenses that change the degree to which they bend, or refract, light. That is, by reorienting the molecules in the lens crystals, emPower! glasses are able to do what ordinary bifocals and no-line progressive lenses do in the lower portion of their lenses by altering their thickness and curvature. The difference is that the bottom reading portion of emPower! lenses can be turned off or on to make it easier for the wearer to see in non-reading situations. Research shows that when people wearing bifocals, trifocals, and no-line progressive lenses look downward while descending a staircase, their view becomes distorted and they are more likely to fall.
