I work at a desk in front of a computer all day . when I first begin my job I would notice that my eye be strain alot . after do quite a bit of research on computer glass for a person with 20\/20 vision , I find this company . they be found by the same guy that found Oakley . this be the only company I have come across that specialize in these type of glass . my experience with they have be perfect . they reduce the strain on my eye from the computer as well as the overhead light . at first it be a little bit strange wear glass and have to answer all the question about they but I have grow to love they and recommend they to anyone who be notice soreness or strain on they eye from stare at a computer screen ! you eye be well worth the $ $ when I notice my eye strain I will put they on and my eye instantly relax -lrb- very similar to the way sunglass work outdoors -rrb- , make it easier to focus for longer period of time and increase my productivity .
