Eye strain

I recently got the 2013 "14" Razer blade and I'm getting eye strain. It has a 1600 x 900 resolution And I was wondering if there any way to reduce my eye strain.

I used to get really bad eye strain. I did most of my work at night, and this program helped a ton! 


It annoyed me at first, but I go used to it and now I love it.

ps. Don't use it if you are doing any color sensitive work   

Does it change it drastically
