Agree with the points about the difference in frequency of screen and fluorescent overheads, but there are a lot of other reasons for computer eyestrain as well. We’ve studied this for the better part of a decade now, and patented what we feel to be the best, most comprehensive solution out there. Definitely helps to get involved in the setup of your work environment…ie lighting, workstation height, monitor selection, etc. But you should also consult your eye care professional and get your eyes checked regularly. Just about every doctor will let you know that computer eyewear will help.
Definitely not designed for driving. They have a focusing power for a specific viewing distance. The ‘magnification’ is actually a byproduct of that focusing power. Bottom line is that the glasses help your eyes relax when viewing things in the near distance. If you use them to view things in the far distance (ie driving) they aren’t going to work well.
Good facts here…we just need to dig a little further. The red/green cones are concentrated on the central part of the retina and blue cones are scattered closer to the periphery. Here’s where the interesting part comes in. The fovea centralis is the part of the retina where the high level visual processing takes place. Nerve endings are 100x more dense here…and there are almost no blue light receptors. For anyone that has skied on a whiteout day, you’ll know that with amber lenses, you can actually see the terrain, but without them, you can’t. Why? too much blue light blasting at your eye keeps you from using the most sensitive part of your retina. Filter it out, and you’ve got more visual sensitivity. Same applies to the computer screen…especially any document with a white background.
Add in the focusing power that relaxes your eyes, and high wrap that keeps your eyes from drying out, and you’ve got a very robust, doctor recommended solution.

I don’t know the exact density of the cones in the fovea centralis in comparison to the other areas of the retina but I do know and agree that it is by far the most sensitive to (colored) light. And that it also has only a scarce supply of blue cones. So maybe there is a bit of science behind these glasses. - medical student who is studying for a neuro test tomorrow…
Wow! Straight from the horse’s mouth (A response form GUNNAR CEO)
Interesting discussions btw. Given in future more and more people will be looking at handled led screens, any help to reduce eye-fatigue of any kind by any percentage is indeed of a great help & will get wide acceptance. 10 year ago where a normal person will smile @ fellow commuter, look around, look at people walking, look at street lights/crowd/posters (aka object @ various distances), NOW all we do is what now? majority of folks I see in public places do is KEEP STARING at their phones and NOTHING ELSE. My optometrist also told me same thing that since eyes are pretty much made to work more at a fixed distance/light source all the time, strain on people eyes in last decade is gone exponentially high and will be only going north from here on. A totally different world now, something for which our eyes were never designed for. So yes anything in this front is of great help. In4one …
I use a PC 8+ hours a day as well as game on the weekends and I have had two pairs of Gunnars for the past two years. Won’t work or game without them on and even makes watching sports on TV that much better. Every single person I let try them on has asked where they could get a pair.
Makes perfect sense, actually. Thank you for taking the time to read the thread and respond to folks. You’ve convinced me to pick one up on that alone, although my mind was already made up before that.
Looking forward to trying them out!
What your eye doc may or may not have referenced is the fact that the NEI (National Eye Institute) which is a division of NIH (National Institute of Health) published a study a little while back. It showed that the rates of myopia (near sightedness) are skyrocketing. Over the last 25 years, the rates of this eye disease of increased 66%. If any other disease had done so, it would be surrounded by a major media frenzy and have the term “epidemic” thrown onto it. We just need to get proper education around how to adapt to our changing environment and use the proper tools. I’ve committed the last 10 years to studying this field and have 20 years in the optical field. Most of what we do at GUNNAR is just apply solid optical principles to a very real problem. No rocket science, no snake oil. Just things that you can go to your eye doctor and confirm…extended computer use causes eyestrain. GUNNAR is a solution.
Personally, I absolutely love mine. I spend nearly all of my time on the computer (job is working on a website, computer science major has my homework on computer, free time is gaming on computer) and they’ve helped drastically with eyestrain and general fatigue after long sessions on the computer. I have the anime style ones, and I get lots of compliments when I have them on. But I wear them for the functionality, and that they perform very well on. I’ve had considerably less headaches since I got them. The only thing that I don’t like is that they didn’t come with a glasses case, so I’m constantly paranoid I will break them.
Thanks for the heads up, I as not aware of that,
Thats what I thought too.
Read my experience with that in the above post…
Most of the pros and cons of these glasses have been discussed thoroughly already so I won’t rehash them, but I’ll bring up a few points I haven’t really seen.
These glasses have a pleasant side effect of making a room that’s lit by indirect daylight feel sunny. It actually helps my mood.
The slight magnification doesn’t really make things any sharper. The lenses just aren’t high enough quality to give you any additional edge detail. I don’t feel there’s any net benefit to the magnification.
The glasses work best within an arm’s length or so. Beyond that things start to get fuzzy. “Real” gamers might think “computer”, but I think “Xbox”, and these just aren’t good for gaming on a TV across the room. I tried once and experienced more eyestrain trying to keep things in focus. I definitely wouldn’t drive with these.
Depending on your lighting environment, you may see more inter-reflections from the lens itself. Some of the blue it tries to reflect away from you ends up bouncing back to your eyes. It can be somewhat distracting.
Overall, I do like wearing them for computer use, but they’re not for everyone. YMMV.
I was being modest with the “research scientist.” Actual credentials went far beyond that, including 50 patents 'nuf said. You DO make some good points and good credibility as an actual USER of RayBans, etc. At high altitude especially, the UV (blue, as you call it) is indeed SEVERE and harmful. Like you, I wear and swear by the Aviator glasses (genesis of the RayBan line circa WWII). CVS is more aptly addressed with more “time outs” from the monitor, exercise and talking to real people who are actually there. People whose work requires staring at a monitor all day are the most affected. Plain old-fashioned fatigue. Hey - if they seem to work, go for it. ~inflationary~
I have wooted many a woot, but never have I missed a woot between the time I added to cart and the time that I went to checkout.
Missed it by seconds - seconds!
Maybe GUNNAR Optiks next time.
