Bias Lighting Decreases Eye Fatigue, But How?

Lately a trend in home theater set-ups is to use bias lighting. You've probably seen pictures of bias lighting around the internet over the last few years, it's like your HDTV died and got its well-deserved halo:



This type of lighting looks awesome, but it's also got a utilitarian purpose: to reduce eye fatigue. But how does it work?

It's kind of counter-intuitive that adding MORE light to your home theater setup should help you strain your eyes less. This phenomenon is mostly based on the averages your eyes take in across their entire field of vision, not just the TV screen.

This means that if you are looking at a really bright screen in a dark room, your eyes are already doing quite a bit of work in perceiving how much darker the surrounding room is compared to the screen, making the contrast ratio between the screen and the rest of the dark room the focus. By making the area around the edges of the TV screen brighter, your eyes are freed up to begin focusing on the contrast ratio offered by the TV.

This of course does not only apply to your home theater, but to your computer monitors as well.
