WHAT IS
ANTI-BLUE LIGHT
PROTECTOR
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.
Where is the blue light?
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.
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
