The 1.55mm-thick lenses incorporate a skinny reflective telescope made of mirrors and filters; bearing in mind light enters the eye it bounces off the series of mirrors and increases the perceived view of an plan or person. It is hoped that the lens will attach the sight of people when age-complex macular degeneration (AMD) -- the third leading cause of blindness globally.
AMD causes the loss of central vision due to gradual flashing to the eye's retina and there are few options for cure or treatment. "AMD is the biggest difficulty where augmentation is a proven visual aid," says Eric Tremblay, research scientist at EPFL in Switzerland.
Tremblay led the optical design of the lens, which is based concerning the order of a surgically implantable telescope currently used by some patients as soon as AMD, but which is more invasive than a lens. "With a right to use lens, it's easy to attempt it," says Tremblay.
Getting smarter
These are not the first invented lenses. Other prototypes have been developed to monitor, as quickly as complement, health in both the eye and across the body.
Alcon, the eye care isolation of Novartis, formed a partnership associated to Google X in 2014 to manufacture smart-lens technologies for a range of medical eye care applications. One of the first examples of using lenses in this form was Sensimed, a spin-off plus emerging from EPFL. Sensimed's Triggerfish technology monitors the encroachment of glaucoma -- the second leading cause of blindness, affecting more than 4.5 million people globally.
Glaucoma is a highly developed cause of blindness caused by deterioration of the eye's optic nerve. The conventional test used by optometrists to monitor patients uses puffs of manner to play in pressure in the eye but such measurements are not ideal.
"The omnipotent mannerism in glaucoma is for a 24-hour describe of what's going on inside the eye," says David Bailey, CEO of Sensimed. Its brilliant lens uses strain gauges and sensors embedded inside a chip located in the lens to decree changes in the volume of liquid in the eye as a surrogate measurement of pressure. It can be worn on severity of a 24-hour time to monitor pressure patterns and communicate data wirelessly to a recording device worn the enthusiast's neck.
Optometrist James Wolffsohn, spokesperson for the British Contact Lens Association, looks talk to to one hours of day using technologies in the midst of the telescopic lens in clinical practice. "The lens seems an tempting concept to offer optical further details to the retina subsequent to required," he says. But he adds that there will be challenges in reaching that stage: "It is currently a scleral lens and thick, including rigid mirror elements which are likely to play in corneal physiology and comfort." Wolffsohn has seen colleagues procedures the more traditional Triggerfish technology to monitor glaucoma and is optimistic approximately the behind of the auditorium. "There are furthermore many new carefree developments in protester uses of admittance lenses," he says.
"The eye is the window to many complaint states," says Bailey, who believes right of access lenses are the detached for eye care, both in terms of clinical use and lifestyle doling out. More than 30 million people wear manageable lenses in the United States alone, according to the Centers for Disease Control, which means they could be a non-invasive alleyway to health giving out -- be it blindness progression or even insulin or alcohol level monitoring.

Technology is growing every day, as it's very helpful for things for human beings life. Everyone in the world is dependent on technology for some work purs=pose. I like the concept the contact lens with built-in telescope. keep posting such kind of informative blog. I will be touch in your blog for trending technology updates. I also found some very informative for technology at NewsWatch TV. I hope you will also found some interesting news of technology there. Thanks again.
