Bias Light 101 : You may ask, "Besides looking cool, why do I need a bias light?" To answer that question I will explain a little about how our eyes work. Every moment your eyes are open your eye takes an average of light from all sources in order to know how much to open the pupil. The greater the contrast of brightness of light from the sources causes a greater strain on your eyes. For example, when you look at your TV screen, your eye is taking an average amount of light between your bright screen and your dark wall. The light contrast causes a higher stress on your eyes. The Sewell Relief Bias Light reduces that stress by reducing the contrast of the light from the screen and the wall. Installation Guide : 1.
