Is there any way to lower the brightness further than the minimum brightness setting? I would like to not have my retinas burned at night.

If there is no solution to lowering the backlight, then is there some magic formula in which I can change the gamma/brightness/contrast values without totally messing up my ability to differentiate between #333333 and #000000? (i.e. not let black and dark gray look like they're both totally black)
