Research leads to innovative new lens
New research into eye health and the effect of prolonged exposure to digital devices has led to the introduction of innovative lenses designed to filter artificial blue light emitted from computer screens.
Crowd-funded Australian start-up EXYRA has developed a ground-breaking lens that blocks natural and artificial blue light from entering retinas and causing muscular and visual damage to the eyes.
The eye’s natural lens is not designed to filter artificial blue light from computer screens, tablets and other hi-tech devices.
Yet, as a society, Australians have become massively technology-dependent, with the average household using up to six different digital devices daily for two hours or more.
This includes for work, school and pleasure.
Prolonged exposure to such devices, more specifically the blue light emitted from LED screens, can be detrimental to overall eye health.
This can lead to a range of symptoms, including but not limited to, eyestrain, headaches, fatigue, neck and back pain, and blurred vision.
The newly developed lenses, offered in a range of optical frames, are currently being used in non-prescription and prescription applications, but not yet as bi-focals or multi-focals.
The option exists, however, of upgrading lenses to include greater magnification, allowing the wearer to accommodate varying degrees of contrast without the need for excessive focussing effort.
The glasses are specially designed to optimise vision when viewing digital screens by reflecting high energy blue light and enabling healthier blue-turquoise wavelengths to enter the retina in order to enhance full colour perception and protect the eye from muscle strain.
The lens’s multi-layered construction also protects from UV damage, including glare.
