I'm wondering if certain types/brands of monitors can actually cause eye strain? When i had my Belinia 22" 60hz screen i didn't have any issues...but when that died i got a LG 23" 120Hz and it makes me tired and have eye strain..even wearing Gunnar Optics doesn't really help out that much. I had an eye test to make sure i didn't need glasses and they said my eyesight was perfect....so im not sure what's really going on. What about IPS monitors?..do they help with eye strain? Also i read about BenQ (GW2760HS) banishes eye strain by using Direct Current back light system rather than (Pulse Width Modulation (PWM) which is suppose to cause these issues.
