Review on Gunnar Optiks Valve Computer Gaming Glasses by Mark Vazquez

These are my second pair of Gunnar computer glasses. I started getting severe headaches and eyestrain from staring at the computer all day at work and I bought my first Gunnar glasses and they worked! When I lost my first pair of glasses I went back to the cheap $20 (not Gunnar) computer glasses I had before and after the first day of work my eye strain and headaches came back. So I had to order a new pair of Gunnars IMMEDIATELY. My first pair was the Enigma, but I like this pair of valves even better. I highly recommend it if you sit at the computer all day.
