Lazy eye, or amblyopia, is a reasonably common disorder affecting around two or three percent of children that can lead to serious loss of vision in the long term. The two most common methods of early treatment are eye patches and eye drops, but both require a disciplined approach and are uncomfortable in their own ways. Researchers have now developed electronic glasses that can be programmed to automatically build the brain's reliance on the weaker eye, with the initial trials suggesting they might be as effective as traditional methods of treatment.
The potential for replacing aging or damaged eye lenses with artificial lenses that do more than just restore eyesight has long been recognized. With everything from telescopic capabilities to those with built-in heads-up displays, electronically-enabled synthetic lenses promise to bring useful cybernetic enhancements to the human body. In pursuit of this goal, one researcher at the University of Leeds is developing a unique, auto-focusing liquid crystal lens that may help cure age-related long-sightedness.
It's always handy having a spare pair of glasses on hand, but paying for
a second set of prescription specs is something that most of us would
prefer not to do. Well, that's where Adlens Adjustables come in. They're
inexpensive glasses that can be focused by the user to (more or
less) match their prescription. We recently gave them a try, and can
tell you that they work ... but you probably won't want to use them as
your primary glasses.
Taking time out of your day to make an appointment and see an optometrist isn't always that agreeable, and that's before they blow those little puffs of air onto your eyeballs. But one Chicago-based startup has visions of making eye examinations a lot more accessible. Since 2012, Opternative has been developing an online eye tester that lets users obtain prescriptions for glasses and contacts from the comfort of the home or office. And now with clinical trial success under its belt, it's rolling the service out to the public.
For people who suffer from being "locked in" with Lou Gehrig's Disease, or ALS, there aren't many reasonably-priced options that enable communication with the people around them. EyeControl is trying to change that by creating portable glasses that allow ALS sufferers to communicate using their eyes.
A few years ago, UK-based Adlens developed self-adjustable glasses designed to let those in the developing world dial in their ideal magnification level – no optometrist required. Now the company is bringing the technology to the developed world as an alternative to bifocals. Instead of looking through a different area of the lenses (and tilting your head forward and back) to switch from near to far objects, the magnification of the AdlensFocuss glasses is adjusted by a small dial on the arm.
I wouldn't normally pay too much attention to such a seemingly minor thing as eyeglass hinges, but Spine Optic's extraordinary 3D video animation caught my imagination. The company's range of frames feature a nifty self-closing hinge inspired by the human backbone that holds the glasses firmly in place on your face and offers extra flexibility to fit different sized heads.
