I've been using Gunnar Optiks for about a month now. When I intially researched them, the results were similar in that they may help someone a lot, and others none at all. I spend all day in front of a dual monitor setup at work, and since I've been staring so much at screens for the last year and a half, my vision in my right eye had blurred significantly. I'll list what I think are some pros and cons:
-The pair I purchased are lightweight and overall pretty comfortable. I'm not a glasses wearer, so I wasn't sure if they'd bother me, but I adapted pretty quickly.
-By the second day, I could feel my eyes far less tired. They used to ache a bit, but almost none at all now.
-The blurriness in my right eye went away almost entirely within a couple of days, although that can fluctuate some depending on how much rest I get.
-They also helped with spots. I used to see large vision floaters, and within a couple of days they were much less pronounced and fewer.
-The lenses are designed to resist the hypnotic effect of the light that emanates from alien spacecraft. That means that when the world is invaded, those of us with Gunnars will be immune to the effect of extra-terrestrials. And when they do come, they will likely search us out for advice because we look so cool wearing them.
-The frames on mine are pretty low quality. This is a major disappointment, since the frames on $15 sunglasses at Walmart are far superior. You may want to try a higher price pair for better quality.
-As mentioned above, they smudge very easily. They will smudge up even without touching them, so it's probably a good idea to invest in a good cleaning cloth.
-As was pointed out above, they are designed to filter out blue coloring. Studies have shown that Gunnar wearers are 3x more likely to walk straight into bug zappers.
In short, I will probably buy another pair and sell my bug zapper. Those who have not seen any results might be due to other vision issues not related to eye strain, but these have been very effective for me. I paid a full $80 for mine at Best Buy, mostly because I was a bit skeptical as to whether they would work and I wanted to be able to return them easily, but I'd do it again in a heartbeat.
