A recent study published by French Agency for Food, Environmental and Occupational Health & Safety (ANSES) revealed that the "blue light" in LED lighting can damage the retina (back of the eye) and disturb natural sleep rhythms. The report also claims that long-term exposure to LED lights can accelerate the ageing of retinal tissues, leading to an early onset of Age-related Macular Degeneration (AMD). As the name suggests, AMD is a degenerative disease that affects the macula (centre part of the retina), causing irreversible vision loss.

Over the last few years, LED lights have become very popular in India. LED lights are widely used in our country, both indoors and outdoors because they use lesser electricity and hence are easy on the pocket. In fact, LED lights are all around us – in our mobile, TV and laptop screens.
