We are told from a very early age that too much screen time in front of a TV, a smart phone or device or a computer, is bad for our eyes. The problem is caused by the blue rays emitted from the devices.
Researchers have found that deep blue light, which is close to ultra-violet light, is particularly harmful to the eyes. This poses a huge threat to children whose retinas are clear and who will be exposed to the rays for 40 or 50 years.
The solution is to limit time in front of electronic devices to no more than 6 hours per day and to invest in a pair of blue-blocker glasses, which are available at selected optometrists or over the Internet.
