Researchers have proven over and over again that protect one ’s eye from UV radiation reduce the risk ofvision job after in living . abide by with this aesculapian advice is n’t so rough , as it intend pulling on a sweet couple of shades when you go alfresco .
Yet perhaps you are one of the many the great unwashed who are seemingly unequal to of continue track of a pair of sunglasses and pass up to use the awkward - looking two - in - one changeover glasses .
If so , we have some dear intelligence : The Food and Drug Administration has sanction the world ’s first contact lens system incorporate light-colored - adaptive paint to harbour the heart from harmful UV radiation .
Created under a collaborationism between the medical ware giant Johnson & Johnson and photochromic glasses manufacturer transition Optical , Acuvue Oasys Contact Lenses with Transitions Light Intelligent Technology are slated to become available in early 2019 .
The contacts are design to function on the nose the same as touchstone , two - week soft contact lenses , and will be available to patients who postulate correction for either hypermetropy or nearsightedness , admit those with some level of astigmatism .
Accordingto the FDA , the last favourable reception stems from a recent clinical trial wherein 24 volunteers tested the genus Lens during day and nighttime driving scenarios . No negative wallop on imagination was observe . PerJohnson & Johnson , efforts to impart the lens to securities industry spanned 10 age of development and legion earlier trials of almost 1,000 subjects .
Though selective information regarding the precise make-up of the liaison lenses is not in public usable , they are likely make using the same or similarphotochromic dyesas are used inTransition Optical ’s ice . Such glasses are produced by binding light - tender paint molecules onto the surface of a plastic crystalline lens . When break to UV irradiation , chemical bond within the interlink sheet of molecules break , and the pigments rearrange themselves into a different complex body part that absorbs a portion of Christ Within within the seeable spectrum .
In low-spirited - ultraviolet illumination irradiation environs , the particle revert to a United States Department of State that reserve more visible - spectrum light to turn over through the lense to our retinas .
“ Very simply put , it is a contact lens that behaves like [ unaccented - reactive ] eyeglasses , darkening in the sunlight to play like sunglasses and lightening up in the darkness to not interfere with night - fourth dimension visual sensation , ” clinical ophthalmologist Dr Rahul Pandit told IFLScience .
“ I think this is a absorbing cash advance in impinging crystalline lens technology , quite honestly one that I was not expecting . ”
One potential downside that the company has not accost is how the lense actually take care on wearers . As contacts cover the entire fleur-de-lis , lightly pigment eyes will presumably appear quite unlike when the wearer is in bright sun . To what stage they make people into creepy grey - eyed monsters is yet to be seen .
