Blinkies (LED's) may cause irreversible eye damage

[FSEP]

London, May 15 (PTI) The so-called eco-friendly LED lights may cause permanent damage to your eyes, a new research has claimed.

The study found that exposure to light-emitting diode (LED) lights can cause irreparable harm to the retina of the human eye.


Once the retina cells are destroyed by prolonged and continuous exposure to LED rays, they cannot be replaced and will not regrow, ThinkSpain.com reported.


Researchers said 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, mobiles and TV screens, and even traffic and street lights, have been gradually replaced with LED.


Experts are calling for the lights to have built-in filters to cut out the blue glare.


Dr Celia Sanchez Ramos, investigator at Madrid''s Complutense University, said the retina, a highly-sensitive tissue covering the eye, never regenerates itself once it has become damaged.


Ramos said 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 said.


Humans have their eyes open for around 6,000 hours a year, and most of this time they are exposed to artificial light for which reason Ramos says the best way to prevent damage is to "close your eyes often to soften the impact".

Next scientific revelation...loud sounds damage hearing. Recommended protection is to walk around with your fingers in your ears.

While I understand the effectiveness of the LED lights, I'll take a good ol incandescent bulb over a LED or compact fluorescent any day. The LEDs are just too crisp. Many of the municipalities around here are slowly phasing out the High Pressure Sodium street lights to crisp white LEDs. I can't stand it! Hurts my eyes big time. I enjoyed the HPS, LPS, and good ol fashioned mercury vapor street lighting over the LEDs. I know the topic is more related to emergency vehicle lighting but just wanted to throw that in there.

I think it'd be way cool if they just removed overhead lighting and put strip lights on the corners of sidewalks to illuminate the roadway.

More reason to use blue lights sparingly. They're effective enough at night that you only need a couple of them visible in any particular direction, never mind a full blue LED lightbar.

But then, you can't sue your fire department for hearing loss for the siren on your truck!!! DOH!!!


Just noticed on our ambulance siren a warning on the faceplate: May Cause Hearing Loss!
