The first thing you should know is that I NEVER review products. Despite my background in psychology and research, I often find reviews to be too polarized and overwhelming. This product, however, deserves a stellar review and I'm going to try my best to offer a concise, helpful review for anyone who might be on the fence about buying these.Background story: I have had Dry Eye Syndrome (DES) for SEVEN years. Seven. I had LASIK surgery at age 20, and I have had varying degrees of DES ever since. Now, to be fair, I did not begin working long hours on a computer screen until after the surgery so I cannot say for sure that LASIK is the culprit. We all know that computers and blue light are bad for our eyes. The bottom line is that we did not evolve to do this -- we did not evolve as a species to sit in front of a bright, harsh-lit screen in bright, harsh-lit offices for 8-12 hours per day. However, once you've permanently changed your eyes and felt the sting of regret after being worn down for seven years trying to find eye drops, glasses, contacts, etc., to cure the ailment that you inflicted upon yourself for having LASIK in the first place... you get a little frustrated and it's hard to see beyond "I shouldn't have done this..."Now, fast forward seven years to present day. I ordered these glasses to figure out if I should put a coating on my reading glasses (yes, I know need reading glasses at a low prescription due to LASIK). I figured that they're fairly inexpensive and I might as well give it a shot. HOLY 5-STAR REVIEW, BATMAN! -- These glasses have CHANGED. MY. LIFE.I now wear them while driving in twilight or at night, to watch TV, to work at the computer, to play around on my iPad or iPhone -- ALL THE TIME. I wish I could permanently make my vision look like this. This is what I've been trying to achieve for YEARS. Not only do they greatly relieve eye strain, but honestly they make everyday life easier for me to look at. My eyes are sensitive to light and I see halos/glares after LASIK especially when my DES is particularly aggressive... that stuff is GONE while I wear these. These glasses aren't just a solution for eye strain -- they're a solution for post-LASIK misery. Here is a list of reasons why I love these:1) They are not super yellow. My coworkers notice sometimes, but it really isn't that noticeable. It also doesn't distort your quality of vision. Things look a little more sepia toned or yellowed out, but it's honestly comfortable for anybody who has sensitivity to light.2) They are very stylish and feel like good quality frames. They are heavier than my $180 Ray-Bans. Seriously.3) The arms have a spring, so they fit comfortably on my face and the faces of my curious coworkers without slipping. They also don't feel too tight.4) They block some, but of course not all, blue light. Any glasses that are not straight up amber are not going to block 100% of blue light. I think they block around 30% according to the product info. For most people this will tremendously help, but of course some will require stronger stuff.5) They are great for driving at night -- they reduce the glare of the headlights for me and make headlights far less of a pain without making it difficult to see.6) They're CHEAP. C'mon, guys. A box of eyedrops for DES usually costs more than these.7) I use LESS eyedrops now. They provide a shield over your eyes (this is important if you have DES), which reduces the air that hits your eyeballs. Also, with less eyestrain, I find that I am not reaching for my eyedrops to provide relief.Just do it. Buy the glasses. If you hate them, return them. But I'm telling you I might buy five more pairs just to have a pair for every situation: at work, in my car, at home, an extra pair, in my purse, HELL I'd keep a pair in every freaking bag I own just to make sure I always have them. My eyes have NOT BEEN THIS COMFORTABLE IN SEVEN YEARS. Buy the glasses. I hope you love them as much as I do.
