Electronic Spectacles Shove Out Traditional Bifocals

With the invention of electronic glasses, traditional bifocals will soon be out of fashion. The new creation automatically adjusts and enables the user to view objects at different distances.

By pressing a button on the side of the frames, the glasses can be adjusted manually to view objects at diverse distances.

Presbyopia - Causes, Symptoms, Diagnosis, Treatment & Prevention
Presbyopia is a physiological visual condition occurring in middle-aged individuals wherein there is an inability to focus on near objects.

The spectacles, which would be launched in the US this year and the UK next year, have been developed by US firm PixelOptics.

"Unlike traditional bifocals, which only allow the wearer to focus "near" or "far", the electronic lenses have a range of in-between settings. We have been developing these glasses for the past 10 years," the Telegraph quoted Peter Zieman, director of European sales for PixelOptics as saying.

"Liquid crystals can change their refractive index when an electrical charge is put through them, so wearers can switch between distance and reading in the time it takes to blink.

New Age Bi-Focal Contact Lenses Developed Now For Presbyopia: Helps Sharpen Aging Eyes
Optometrists at the University of Alabama at Birmingham (UAB) have come up with a new breed of contact lenses that can treat presbyopia, a gradual loss of the ability to focus

"Putting in the kind of motion sensors that are used in the iPhone also allows the glasses to sense when someone is reading a book or a newspaper and so change the focal distance of the lenses automatically.

"Our glasses bring modern technology to an old solution," he added.

Beyond Bifocals: Wavefront Technology Benefits Patients With Presbyopia
For those who’ve reached the age when reading a newspaper means holding it at arm’s length or fumbling for reading glasses, wavefront-optimized lens technology may offer a better solution.
