Sony files patent for contact lens that records what you see

Although electronic devices are shrinking all the time, the idea of a smart contact lens still seems wildly ambitious. Now Sony has reached even further into the realm of the hypothetical and yanked out something that trumps all the efforts we have seen before. A patent filing by the Japanese company reveals its vision for a contact lens that not only records video and images with a simple blink, but manages to store them right there and then on the user's eyeballs.Read More

Nosy fish inspires help for the eyes

Presbyopia is a common visual condition, in which the eye's lens stiffens to the point that it can't focus on close objects. Glasses, surgery and regular contact lenses do help, but they also cause a loss in contrast, sensitivity and night vision. That's why scientists from the University of Wisconsin, Madison are developing an alternative – self-focusing contacts that are inspired by a fish.Read More

Electrical contact lens eyes glucose monitoring and augmented reality

Smart glasses haven't quite taken off as some might have hoped, but that doesn't mean another form of eyewear can't offer users a worthy augmented reality experience. Australian scientists have developed an electrically conductive contact lens with the potential to host miniature computer displays and sensors to help monitor health.Read More

Opternative's online eye-testing service returns prescriptions in 24 hours

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.Read More

Telescopic contact lenses zoom in and out with the wink of an eye

Researchers from the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have developed contact lenses that have tiny telescopic lenses built in to boost vision. Controlled by smart glasses that react in response to the winking of an eye, the device allows the wearer to zoom in on objects by providing magnification up to 2.8 times that of unaided human eyesight.Read More

Vision-correcting display lets users ditch their reading glasses

In an age where reading something from a screen on a phone or a computer is a normal part of our daily lives, the wearing of glasses or contact lenses often makes doing so a chore with eye-strain problems and the necessity to carry around spectacles or lenses wherever you go. In this vein, researchers at the University of California at Berkeley have created a prototype vision-correcting, printed pinhole matrix that they claim fits directly to a screen and negates the need for eyeglasses or remedial lenses and may one day offer improved visual acuity to those with eye problems much worse than simple farsightedness.Read More

Google announces glucose-monitoring contact lens prototype

While we have seen the technology behind glucose-monitoring contact lenses develop over the least few years, getting them out of the lab and onto the eyes of diabetes sufferers has been a different story. With Google announcing its testing of a smart contact lens designed to measure glucose levels in tears, the search giant is looking to provide more effective management of the disease. Read More

Telescopic contact lens with switchable magnification to help AMD patients

Age-related macular degeneration (AMD) is the leading cause of blindness among older adults in the western world. Unfortunately, conventional optical aids provide little help for a retina which has lost the acuity of its central area. Now a team of multinational researchers led by University of California, San Diego (UCSD) Professor Joseph Ford has created a telescopic contact lens that can switch between normal and magnified vision to offer AMD patients a relatively unobtrusive way to enhance their vision.

Curved LCD could be used for displays in contact lenses

New research conducted at Ghent University, Belgium, has resulted in the development of a curved LCD display which can be integrated within a contact lens. While still in its infancy, the project lays the foundation for future fully-pixelated contact lens displays which could be used for both medical and cosmetic purposes, in addition to a heads-up-display (HUD) further into the future.Read More
