Just as the title says. Wondering of there is something special about lenses sold specifically as blue light blockers, or if any red or orange tinted lenses will do. Already have f.lux on the computer, but I get off work late in Tokyo and the walk/train ride home exposes my eyes to a ton of bright blue light.
I use red bulbs at home, and feel it really simulates sunset lighting and makes me sleepy fast!
I've used these with good success, although I haven't tried the more expensive ones that are specifically designed for the purpose as a comparision. Many of the reviews for them are regarding blue light blocking however and you can't beat the price. They are not the most comfortable to wear but I can watch a movie or work on the laptop for a while and they are just fine.
While not the same of orange and quite expensive Gunnar makes several kinds of glasses of that color and in much nicer frames. They do magnify a little bit so that might be an issue. I think it's +0.25 diopter or something like that.
Yes, there's a reason that the orange-amber tint color has been trademarked as "BluBlockers". Any optical store should be able to put some tinted lenses in a regular frame so you can wear them around without looking like a dork ;)
You can buy clear glasses for indoors that block the short
UV rays which can damage eyes. They are specially made
and you can ask for them at an opticians. They are recommended
for people with macular degeneration and other eye problems,
