Sore eyes

[Squidgy_wiji]

Hey for first the first time in my short poker career i am doing nothing but poker at the moment.. My goal is to play 8 hrs a day for the next 4 weeks.

Its been going alright but i;m getting really sore eyes from being in front of the computer for so long...
So i'm sure alot of you pro's out there would have encountered this before..
Can you recommend any products or eye exercices that you may do to deal with this?
