Recently, a new research has claimed that the so-called ecofriendly LED lights may cause permanent damage to your eyes. The study found that exposure to LED lights can cause irreparable harm to the retina of the human eye. According to Think-Spain.com, once the retina cells are destroyed by prolonged and continuous exposure to LED rays, they cannot be replaced and will not regrow. 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 s...
