Contact Lenses

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.

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.

Earlier this year, Google announced that it was testing a glucose-monitoring contact lens. The lens is aimed at helping people with diabetes better manage the disease. A partnership has now been announced with Alcon, which is the eye care division of Novartis, to commercialize the technology. Read More
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
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.

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.

For younger readers with perfect eyesight, here’s something you might not know – glasses and contact lenses don’t do anything to cure nearsightedness, they only help compensate for it. In fact, the wearer’s vision often continues to deteriorate as they age. Now, however, a team of scientists have developed special contact lenses that they claim can halt the condition if it’s caught in childhood. Read More
The iOptik display system, consisting of modified contact lenses and glasses, promises to revolutionize head-mounted display-based augmented reality by allowing the wearer to focus on two planes at the same time. Innovega, the company behind the project, developed their ultra-small form-factor head-up display (HUD) setup in frames of DARPA’s Soldier Centric Imaging via Computational Cameras (SCENICC) program, and has now signed a contract with the agency to deliver a prototype.

We've heard of experimental contact lenses that can non-invasively monitor the blood sugar levels of diabetes sufferers before, but where prior research relied on chemical reactions inducing color-change in the lens, new joint research by the University of Washington and Microsoft Research aims to incorporate electronics into such lenses to report blood sugar levels wirelessly. Gizmag spoke to Desney Tan, Senior Researcher at Microsoft Research Connections, to find out what sets this work apart. Read More
Fans of the original film in the Terminator franchise will recall how various bits of data were shown to be overlaid on the cyborg's vision - in particular, they might remember the list of possible responses that could be used when someone was angrily knocking on its door (for those who don't remember, its chosen response wasn't very polite). Such augmented vision systems are now a little closer to reality, thanks to work being done by a team of scientists at the University of Washington and Aalto University, in Finland. They have created a contact lens that displays information, which is visible to the wearer. Read More
