Buy this if you have money to burn or if you care a lot about your eyes that you can sacrifice a 4.5k for them. For me it's the latter case. I read stuffs every night on my Nexus 7. But even at minimum brightness, it is so bright it lights up the whole room. After getting used to reading at night with these glasses on, it hurts even more if I try to read without it. I only use these glass for reading at night and my eyes feel a lot better in the next morning. Pros: * Works for me * You can safely buy this glass online because the model fits all types of face shapes. * Very lightweight * Supports Headphones * Looks great * No screws Cons: * Very fragile. You might break the hinges even if you just simply try. * For 4.5k, it doesn't even come with a case especially it being very fragile. * Too expensive. Could be 3 times its actual worth.

I am an IT engineer. I sit on PC for about 10hours at least a day. I really needed something that could protect my eyes. These glasses works in relaxing your eyes. The feeling is difficult to explain ,but don't expect an overwhelming change the moment you wear these. I used it for almost 3-4weeks. Believe me an investment of 3-5K is not small amount, but you can care for your eyes more. Unfortunately I have Astigmatism of about cyl(-1.5) . Hence I need contact lenses for clarity too. I recommend not buying if you don't have 20/20(no spectacles) vision. If your eyes are still healthy you can go for it.

Typing out this review wearing these. First thing that comes in your mind after holding these glasses in your hand is, "Shit, I should have got the expensive model." Because: 1. Very fragile. I don't think it can stand even one fall. You don't want to even try. 2. Doesn't fit, they stand up on my nose slightly. Maybe that's the way they are suppose to be. But i don't like it. 2. If this look so cool, i can imagine the expensive ones. Rest all people have already discussed. I am surely getting these replaced with the expensive ones. Because I can't imagine looking at things without these now. I'm in love with Gunnar. Highly Recommended!

i have bee using this product for the pass three weeks and i find the highly use full if you a person whose sits in front of a computer for extended period of time. pros:1) the glasses do prevent eye Fatigue. 2) it dose not flush out all the color on the screen (doesn't make it too yellow), 3)you will automatically get amazing bragging rights XD (TESTED). cons:1)it doesn't fit very well on for me. conclusion:If your a person who sits in front of your comp continuously for 5Hours and you care about your eye I'd suggest you get this or any other design that you like.
