ENERGY-SAVING 'green' LED lights can cause serious damage to the retina, according to recent research by Spanish scientists.
And once the cells are destroyed by prolonged and continuous exposure to LED rays, they cannot be replaced and will not regrow.
This is caused by the high levels of radiation in the 'blue band', and is likely to become a global epidemic in the medium term given that computer, mobile phone and TV screens, and even traffic lights and street lights, have been gradually replaced with LED.
Experts are calling for these to have built-in filters to cut out the blue glare.
An investigator at Madrid's Complutense University, Dr Celia Sánchez Ramos, says the retina, a highly-sensitive tissue covering the eye, never regenerates itself once it has become damaged.
The professor of the University College of Optics at the Complutense says LED lights are made up of rainbow longitude waves, and it is the blue part which causes the problem.
LED is fantastic if there is adequate protection, she explains.

(68,644 posts)I have hundreds of LEDs, from cheapo radio shack ones to one that produces 5,000 lumens (the equivalent of a 300 Watt incandescent), and I have friends in the industry.
The blue light is unpleasant and not useful in most applications, so various schemes exist to convert that light energy into friendly wavelengths.
I fear that the same misinformation that worries people about CFLs will now apply to LEDs, so with big grains of salt do I take any news about LEDs.
