Worrying about my eyes, I've done some reading.
I Think the verdict is out on blue light:
The European Eye (EUREYE) Study "
found that the combination of blue light exposure and low plasma concentrations of antioxidants was also associated with the early stages of AMD, which are common in the population, and that blue light exposure in middle age might be more damaging than at younger ages."
(AMD is accute Macular degeneration), or irreversible blindness.
A study at the Surrey University Chronobiology Center demonstrated that blue light (479 nm) is
only about as efficient as ordinary white fluorescent light in inducing a physiological response (melatonin suppression), even for young people. Studies at Harvard Medical School and Rush University Medical Center were
unable to demonstrate that increasing the proportion of blue wavelengths in a light source improved its effectiveness in shifting the circadian rhythms of humans.
So blue light could severely damage your eyes, and is not effective in its goal?
Most of the above research is linked from
http://www.sunnexbiotech.com/
They obviously have a bone to pick, they have a product to sell (green light) and can benefit from dissing white/blue light.
Their essential claim is that
1) blue light doesnt work and will screw your eyes
2) bright full spectrum light is effective but will screw your eyes
3) Their product (green light) is as effective as full spectrum 10k lux at only 300 lux and wont screw with your eyes
They cite research papers to substantiate all their claims, though the reference on 2) is a bit unclear, and unsurprisingly, the research on 3) have notes on them that they were funded by Sunnex biotech.
Can anyone comment on eye damage from light box treatment or the green light alternative ?
