The F.lux tool is very helpful for your eyes. What it does is changes screen color to adjust to light of day so you do not hurt your eyes. Like if you wake up at night and have to check your phone or computer this tool will adjust the coloring so your eyes don't get stunned by the bright colors.This tool is free for Mac OS X.
