Taking care of your eyes when you’re looking at screens
Artificial light is a given of modern life, and in today’s high-tech world we are increasingly exposed to light emanating from TV screens and computers, tablets, and a variety of mobile screens. Unlike natural light, the spectrum of artificial light is skewed toward High Energy Visible (HEV) light, also called blue light, which, long term, is potentially harmful to the eye.
These emissions also have the short term potential to disrupt sleeping patterns, by affecting natural circadian rhythms, with conceivable ramifications to a good night’s sleep.
There are new lens coatings available, whilst leaving the lens clear, and transmitting as much light as ordinary glasses, deflect a significant proportion of the damaging blue light. The lenses reflect five times more HEV light off the lens than any existing conventional lens coatings, in addition to improving contrast and reduce eye strain.
The benefits of these coatings can be multiplied when coupled with specific purpose spectacle lenses, which are designed for wearers using digital devices and computers for two or more hours a day, those most likely to experience eye strain, and end-of-day tired eyes.
