Hi, Saturn. I saw your earlier post, but I wasn't yet back on Babble from my break. I'm glad you asked again.
At the American Psychiatric Assn convention in Toronto a few months ago, there were several competing light-therapy vendors on the floor. All sold the boxes (which have decreased in size lately), and several sold goggles. One sold visors with GREEN light (http://www.feelbrightlight.com/). I don't remember any BLUE vendors. Anyway, the green salesman told me that it was the only spectrum that actually mattered, and that you only need the light in your peripheral vision, not to look into it. No scientific references are given on the sheet I kept or their web site. The visor was about $200.
The Google CACHE (not the current page!) of the Mayo Clinic page on light therapy for depression says:
“Exposure to the blue light spectrum should be minimal
since it may cause vision problems, such as glare or
macular degeneration.”But Mayo removed that warning! What the heck is going on?! http://72.14.203.104/search?q=cache:hXeFSulGp7AJ:www.mayoclinic.com/health/seasonal-affective-disorder/MH00023+%22seasonal+affective%22+blue-light&hl=en&gl=us&ct=clnk&cd=5
Sorry I can't point you to any scholarly research, Saturn. Can I ask why are you interested in blue light, especially?
