Our eyesight is one of our most precious assets. But it's easy to take it for granted ... until it starts to go wrong. And unfortunately, our eyes are now being stressed at an earlier age than ever before.
For thousands of years, human eyesight has been perfectly adapted to see in sunlight, moonlight, starlight and firelight. But now we are in the age of LED lights, halogen lights, fluorescent lights and screens - computer screens, tablet screens, television screens, mobile phone screens, e-reader screens and much more besides.

“It’s no secret that blue light harms our vision by damaging the eye’s retina." Dr. Ajith Karunarathne
"If you shine blue light on retinal, the retinal kills photoreceptor cells ... Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good." Kasun Ratnayake, 'UT chemists discover how blue light speeds blindness'
A study in 2019 has shown that, over the past seven years, the number of 13- to 16-year-olds who wear glasses in the U.K. has almost doubled. In 2012, only 20% of children in their early teens needed glasses. Now it's 35%.
What is more, 11 million Americans have some form of macular degeneration - the leading cause of blindness - today. Based on current statistics, this will double to nearly 22 million by 2050.
Diagnosis of myopia - short sight - in children has doubled in one generation.
