The dangers of blue light exposure
Post on 7th December 2015
Exposure to blue light generated from our mobile devices is having a serious impact on our eyesight.
According to Scrivens Opticians & Hearing Care optometrist Paul Sidhu, the dangers of blue light, the highest energy wavelength of visible light, is able to penetrate the back of the eye, through the eyes’ natural filters.
He explains: “Blue light has always been around, but what is new is the amount of exposure that we get each day through our growing dependence on digital devices. This exposure is leading to permanent eye damage and ultimately leading to eye diseases such as macular degeneration.”
The main concern is for children, whose eyes are still developing and don’t have the filters in place to help protect eyes from blue light. With so much of their time spent on digital devices, from doing homework to playing games, it’s vital that device time is limited to protect children’s vision from permanent damage.
But adults are at risk too. So what can be done to protect our eyes from harmful effects of blue light? Paul recommends: “In addition to cutting back on usage, avoid spending time on your device before bed. Studies prove that exposure to blue light a couple of hours before bedtime suppresses melatonin and delays deep sleep. By avoiding tech at this time of the day leads to better sleep and makes people happier and more productive at both work and school.”
There are lenses that can filter out blue light which protect the eye from the dangers of blue light. These lenses are suitable for both adults and children and help relax the eyes. Paul concluded: “You might not be able to see the dangers, but it doesn’t mean they don’t exist. By taking these few simple steps to protect our eyes, we can be reassured that your vision will last much longer than any of our technical devices!”
