LED lights in your house can cause irreversible damage to the eyes and lead to a vision-robbing condition, French health authority warns
• ANSES urged officials to revise the maximum limit for exposure to LED lights
• In a 400-page report, the body warned powerful LED lights are ‘photo-toxic’ 
• LED phone, tablet and laptop screens do not pose a risk of eye damage, it said
• But it urged car manufacturers to ‘limit the luminous intensity of headlights’

LED lights can permanently damage the retina and disturb natural sleep rhythms, France’s government-run health watchdog has said. The French Agency for Food, Environmental and Occupational Health and Safety (ANSES) warned powerful LED lights are ‘photo-toxic’.  In a 400-page report, the body cautioned it can cause an irreversible loss of retinal cells and lead to a common cause of blindness.


ANSES urged officials to revise the maximum limit for exposure to LED lights, which emit ‘blue light’ at much higher quantities. LED phone, tablet and laptop screens do not pose a risk of eye damage – but the intense bulbs used in car headlights may. French Agency for Food, Environmental and Occupational Health and Safety (ANSES) warned exposure to an intense and powerful LED light is ‘photo-toxic’

The report distinguished between acute exposure of high-intensity LED light, and ‘chronic exposure’ to lower intensity sources. While less dangerous, even chronic exposure can ‘accelerate the ageing of retinal tissue’ and contribute to poor vision, the agency said. 

Long-lasting, energy efficient and inexpensive, LED technology has gobbled up half of the general lighting market in a decade. And industry experts predict its share will continue to rise, topping 60 per cent by the end of next year.


WHAT IS BLUE LIGHT AND WHAT ARE THE DANGERS? 
Long-lasting, energy efficient and inexpensive, LED technology has gobbled up half of the general lighting market in a decade.
And industry experts predict its share will continue to rise, topping 60 per cent by the end of next year.
However, LED lights emit much higher quantities of blue light than standard incandescent bulbs of comparable brightness. 
Blue light, which has one of the shortest wavelengths, is also emitted by flat screens, smartphones and tablets. 
It has long been suspected to be the reason that night shift workers, exposed to artificial light for longer, have a greater risk of cancer.
The light cuts the body’s production of melatonin, which plays a key role in regulating the body clock. 
This may disrupt other hormones. Both prostate and breast cancer are known to be hormone-related.
And researchers at the University of Toledo last year warned blue light may damage vision and speed up the onset of blindness. 
They found prolonged exposure triggers the death of light-sensitive cells in the eye — which can lead to macular degeneration.
Blue light can penetrate the deeper layer of skin, making skin thinner and more fragile, dermatologists also claim.

The “blue light” in LED lighting can damage the eye’s retina and disturb natural sleep rhythms, France’s government-run health watchdog said this week. From a report: New findings confirm earlier concerns that “exposure to an intense and powerful [LED] light is ‘photo-toxic’ and can lead to irreversible loss of retinal cells and diminished sharpness of vision,” the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) warned in a statement. The agency recommended in a 400-page report that the maximum limit for acute exposure be revised, even if such levels are rarely met in home or work environments.

The report distinguished between acute exposure of high-intensity LED light, and “chronic exposure” to lower intensity sources. While less dangerous, even chronic exposure can “accelerate the ageing of retinal tissue, contributing to a decline in visual acuity and certain degenerative diseases such as age-related macular degeneration,” the agency concluded. Long-lasting, energy efficient and inexpensive, light-emitting diode (LED) technology has gobbled up half of the general lighting market in a decade, and will top 60 percent by the end of next year, according to industry projections.
