World”s first electronic specs to make tedious bifocals history!Published On: Tue, Apr 26th, 2011 | Photonics | By BioNews
If you”re one of the many who rely on bifocal lenses, you may soon get a new view of life this summer.
US-based PixelOptics is planning to roll out the world”s first electronic eyeglasses, called emPower, that will make tedious bifocals history, reports the Daily Mail.
People who wear bifocal glasses know all about how the distorted view they get when looking downwards at the ground.
emPower eyeglasses may look like an ordinary pair of spectacles, but these glasses are at the forefront of a revolution in eyewear.
They allow bifocal wearers to switch between different prescription settings for reading and more distant viewing.
emPower spectacles contain the world”s first electronic focusing lenses, which has a thin layer of liquid crystal that changes its alignment when prompted, thereby changing the strength of focus.
All the emPower wearer needs to do is tilt his head downward or manually touch the frame and the reading prescription is activated – and vice versa.
PixelOptics promises the new glasses will be ”fabricated in all prescriptions… and will be available in numerous high-fashion styles, shapes, sizes and colours”.
The glasses were unveiled last month during the International Vision Expo East in New York and are set for a U.S. release this summer.
Each eight-hour battery charge allows for two-to-three days of switching between focus settings.
The frames have three settings – automatic, manual on and manual off – allowing the wearer to remain fully in control.
One potential drawback is their cost – a pair will set you back between 1,000 and 1,250 dollars, although that includes the frames, lenses, coatings and charger.
