f.lux

This week I tested a program I never heard about before called f.lux, it's a small program that changes the colors depending on the time of the day, to make it easier on the eyes. The screen becomes more yellow at night, and more blue at day. For me it work great, and it even have a 1 hour disable option, for people that does color sensitive work, such as drawing. If you want to test it yourself you can download it on justgetflux.com/, I recommend keeping it 3 days to get a feel for it.

EDIT: You have to set a location to make the program to use the right time. I just put the location in a city nearby, and not directly where I live.
