Do 'environmentally friendly' LED lights cause BLINDNESS?


Do 'environmentally friendly' LED lights cause BLINDNESS?
  • Spanish research has shown that blue LED light can irreparably damage the cells in the eye's retina
  • This is not the first time energy-saving bulbs have been criticised - fluorescent bulbs emit dangerous UV light

Eco-friendly LED lights may damage your eyes, according to new research.
A study has discovered that exposure to LED lights can cause irreparable harm to the retina of the human eye.
LED lights have been touted as a super-efficient alternative to traditional bulbs because they use up to 85 per cent less energy and each bulb can last up to 10 years.
In April, Philips, the world's biggest lighting maker, reported a 38 per cent jump in LED light sales from last year.

They are already widely used in mobile phones, televisions, computer screens and can also be fitted as a replacement for traditional lighting in the home.
LEDs are much more expensive that traditional bulbs - costing around £25 for an equivalent 100w compared to around £1 for an incandescent bulb - although manufacturers claim that consumers make their money back because the use such little energy.

The government announced it was phasing out incandescent bulbs in 2007 after an EU directive banned their use. The 100w bulb was the first to go in 2009 and lower wattage bulbs continue to be phased out gradually.
The ban caused public outrage as customers were forced to spend large sums of money on lighting that not only gave an unpleasantly 'cold' light but also caused some people to report symptoms of itchy skin and headaches.
The government's Enhanced Capital Allowance Scheme, which was brought in to help cut UK carbon emissions, is also pushing the use of LED lighting by offering businesses added tax relief if they use LED and other low-energy bulbs.
Dr. Celia Sánchez-Ramos, of Complutense University in Madrid and who led the study, explained that light from LEDs, or light-emitting diodes, comes from the short-wave, high-energy blue and violet end of the visible light spectrum.
