Gunnar glasses cost a fair penny, despite their being sufficient alternate and free options for the same effect. A slight orange filter can easily be applied to your screen using a program called F.lux - which has the same effect of reducing artificial light emissions from digital screens.
I really hope this works, i know that my eyes have been steadily getting worst since my freshmen year of College. Having only my laptop as a video source, I know i should try to keep my light on at night when i play, but its not exactly practical when my room mate is asleep so i turn off the lights and i know its been killing my eyesight hopefully this will salvage whats left of my eyesight xD
Thanks OP
Edit: This feels really weird my screens all orange haha but i guess i'll give it a shot and if my eyes adjust i wont even notice it.
Just started using this, takes a little while to get used to but i like it so far. I recommend tinkering with the settings a bit while your getting used to it.
