Scientists issued a warning blue light LED is easier to damage the eyes

When blue LED first used in consumer electronics and computer components, all people think it was too dizzy, because it is the one and only. Today, when we are not new to the blue LED, LED exposed a lot of problems for users to worry about. Today, there are a variety of issues about the blue LED in the foreign countries, it exposed the more bright red and green LED products to give people possible harm.

"Is due to longer wavelengths than that of blue green and red to bring people more comfortable B David said Dr. Sliney, the U.S. military experts in health protection and preventive medicine brought to light damage on the human body view.

Sliney continued, the eye lens system of human and not keen focus on blue light, and red and green light can be accurately on the retina with different focus, focus position of blue light will be slightly in front of the retina, which leads to the blue light or halo. Moreover, the color of blue is wider than that of other colors when passing through the eye. Dense blue light sources are particularly prone to this, such as blue, they spread on the retina and then interfere with other parts of the scene. This is what we often say that the "blue dispersion of short wavelength when he is red or green refraction angle is larger, has confirmed that the man in black to blue light in the environment is quite sensitive, so blue LED may be especially not suitable for home theater equipment and computer products in the bedroom, because of their light intensity to the human eye the stimulus is too large. So experts suggest people as much as possible not to choose the electronic device with blue LED lights, at least until the blue LED developed low brightness, but it is estimated that at that time the red and green again?
