The same happens with computer screens. Most offices are under-lit (or over-lit but only if ALL your UI has a dark background).

To get a feel for this, point your cell phone at your desk area and take a picture (without HDR enabled). If you can't take a picture without over– or under–exposing the screen or the wall, then your setup is putting strain on the eyes.

This is absolute quackery.

Your camera's cell phone barely manages to hold approximately eight stops of latitude. Blowing out that pathetic dynamic range has no grounding in relation to any notion of "eye strain".

Eight. Stops. Is. Not. High.
