These incredible next-generation contact lenses can zoom in and out





Vision is another area of health that technology may help fix in the near future, as researchers are figuring out ways of making tiny contact lenses even more useful. In fact, France24 reports that researchers from the Ecole Polytechnique Federale de Lausanne in Switzerland have developed contact lenses that can zoom in and out in response to simple blinks from the wearer. The technology could benefit anyone looking to correct eyesight in the future, with researchers focusing on low vision and age-related macular degeneration (AMD) patients, though the product is just at a prototype level.
DON’T MISS: Google’s smart contact lenses will soon become a reality
Developed initially as a project for the U.S. army and funded by Pentagon’s DARPA, the lenses could one day become available commercially.
“Small mirrors within bounce light around, expanding the perceived size of objects and magnifying the view, so it’s like looking through low magnification binoculars,” the researchers said.
Detailed on Friday at the American Association for the Advancement of Science (AAAS) annual meeting, the lenses are just 1.55mm thick and are capable of magnifying objects up to 2.8 times. The lenses contain an extremely thin reflective telescope and 0.1mm air channels that let oxygen pass.
Interestingly, the contact lenses would come bundled with smart glasses that analyze and respond to the wearer’s gestures — specifically to winks. A wink from the right eye activates the telescope in the lens, while a wink of the left eye deactivates it.

Damian Conway, an optician from Norwich, who is running the marathon, told Sportsvibe it is "no secret" among runners that contact lenses can be more comfortable and convenient than glasses, as it eliminates slipping or fogging up.

What is less well known is that vision has the potential to affect performance in sport because it can impact clarity of sight, body movements such as hand-foot coordination and how people process information, the expert added.

"If contact lenses have a positive impact on a marathon runner's performance, imagine the benefits they can offer someone in day-to-day life.  The Acuvue initiative is a great opportunity to experience the benefits of contact lenses first-hand," he added.

Hugh Brasher, joint race director of the Virgin London Marathon, told the site that wearing contacts could give people the chance to perform at their "absolute best" on race day. 

"As a long-time 1 Day Acuvue Moist contact lens wearer, I know from experience that contact lenses can have a positive impact on performance – and I would never race without mine," he added.ADNFCR-1853-ID-801300095-ADNFCR

Multifocal Contact Lenses – Alcon CibaVision Air Optix Aqua Breathable Contact Lenses Posted on 19 February 2012 by gregorypauljohnson


Summary. Someone working at a desk job all day may want to consider having multiple prescriptions: one for close-up work and one to be used when driving or wanting to see distant objects with exceptional clarity.
Most people have vision correction for nearsightedness or farsightedness. Glasses or contacts attempt to correct for vision challenges without impeding healthy aspects of vision.
If someone sees well close up (nearsightedness), but can’t see things far away, their prescription will attempt to bring distant objects into focus without hindering visibility of near objects. However, this usually isn’t perfect.
Most people who are near sighted remove their glasses when reading, or they may have a weak distant prescription for contacts so as not to strain their vision when looking at close objects. This is where multiple prescriptions can help.
An alternative would be a multifocal contact lens like the Alcon CibaVision Air Optix Aqua Breathable Contact Lenses.
