Light-emitting diode (LED) lights may cause permanent damage to your eyes, a new research has claimed. The study found that exposure to 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 [&hellip

These days, it’s impossible to escape blue light. TVs, computers, smartphones, tablets and e-readers bombard our eyes with blue light emissions day and night. Electronic devices aren’t the only culprits. Energy-saving light bulbs (notably LEDs) may be “green” but they also emit a significant proportion of blue light (also known as High-Energy Visible [HEV] light). While present in natural light, blue light occurs in abnormal proportions in artificial light sources. Blue/HEV light covers wavelengths from 380 to 500 nanometers (nm). Although the eyes’ natural filters block UV light, they do not block blue/HEV light, meaning it is able to pass [&hellip

There are 244 full-body “backscatter” X-ray scanners in use at 36 airports in the United States. They operate almost nonstop, according to the Transportation Security Administration. Other airports use millimeter wave scanners, which look like glass telephone booths and do not use radiation, or metal detectors.” NYT August 6, 2012, 5:26 pm X-Ray Scans at Airports Leave Lingering Worries By RONI CARYN RABIN Even before she was pregnant, Yolanda Marin-Czachor tried to avoid the full-body X-ray scanners that security officers use to screen airport passengers. Now she’s adamant about it: She’ll take a radiation-free pat-down instead any day. “I had two miscarriages before this pregnancy,” Ms. Marin-Czachor, [&hellip

Comment Period Ends June 24th 2013 The Transportation Security Administration, under a court order issued nearly two years ago, has finally been soliciting public comments about its use of body scanners and pat-downs at airports. More than 500 people have offered their thoughts — overwhelmingly negative — so far. The deadline for submitting comments is June 24. The security agency was required by federal law to seek public comment before using the scanners for primary screening at airport checkpoints. In 2010, the Electronic Privacy Information Center, an advocacy group, sued to block the use of body scanners, arguing that the machines [&hellip
