In Japan there is quite a fad about LCD blue light filtering and how they might help reduce eyestrain, etc. The web site of a major computer accessory manufacturer has an English-language press release on iPad blue light filter with a nice graph showing how blue wavelength gets reduced, and has this claim:

Blue light is a color that is also found within natural light. However, its wavelength is extremely close to ultra-violet rays, which are harmful to the eyes and body, and it also has a high amount of energy. Hence, it is said that blue light is able to pass the cornea and crystalline lens of the eye without being absorbed, and can end up reaching the retina, which can cause it to deteriorate. There also concerns that exposure to blue light for long periods of time can have a detrimental effect on the eyes.

Is there any scientific evidence to suggest that "exposure to blue light for long periods of time can have a detrimental effect", specifically at the levels emitted by a typical LCD panel?

Whoa! If the dozen watts of blue light from a monitor hurts your eyes, imagine what the SKY must do! I'm staying inside next to my monitor where it is safe. –  Oddthinking Jan 11 '13 at 10:53
I'm very worried by the idea that light might reach my retina and damage it. I think I should ware a blindfold so that can't happen. ;-) –  matt_black Jan 11 '13 at 17:20
