Virginia Company Creates Dynamic Eyeglasses
tetrahedrassface writes "NewScientistTech is reporting that newly developed 'smart glasses' can change focus instantly from long distance to reading mode. The dynamic glasses change focus using a 5-micron-thick layer of nematic liquid crystal, sandwiched between two pieces of glass, and will be commercially available in 2 years by PixalOptics."
"The idea is to put the focusing power found in the lens of a camera on your face all the time."
That means that the glasses would also require batteries, and would need recharging, and would be heavy at first. Sounds a bit too much.
