How does blue light have a fatal effect on sleep?
Blue light signals to the body through the eyes that it needs to be awake, suppressing the sleep hormone (melatonin).ﾠ
In particular, exposure to artificial blue light 1-2 hours before bedtime can have a fatal effect on the body in the long term.
Why are commercially available transparent blue light glasses ineffective?
The wavelength range from cell phones and computers that we commonly use is approximately 440mm to 460nm.
However, all transparent blue light blocking glasses on the market do not block wavelengths above 420 nm.
