2 Blue Light In the lights of human beings can see, red, orange, yellow, green, blue, indigo, and purple lights are visible, but still, there are some lights are invisible, such as ultra violet rays, infrared rays and etc. Those lights our eyes can see are visible lights, but some invisible lights could not be detectable, including the ultra violet rays, will harm to our eyes. In which the blue light plays a killer roller to our eyes, with an invisible spectrum 380~490mm closed to ultra violet rays. The color exhibits in the interval between the wavelength green & green, and causes blue light hazard on the retina.

3 Where the blue light comes from: TV screen, PC, table, and smart phone. Long period working with those devices, causing the problems of eye fatigue, eyesight damage, dry eye, especially Macular degeneration. Scientists have proved that the presence of blue light is harmful to our ocular health nowadays, and brings us a long-term effect of macular degeneration crisis. More people are spending time in front of video display terminals which produce blue lights, hence, it is suggested to wear lens/protectors to reduce the damage from the harmful lights. Where is the blue light?

4 Benefits of Anti-Blue Light Protective Filters Cut off the blue light to human eyes Reduce the glare effect to human eyes Keep away from eye fatigue Maintain ocular health Anti-Ultra Violet Rays Keep device longer life Protect display from scratch or break
