Swanwick Blue Light Blocking Glasses for Women, Men. Sleep Aid. Anti Eyestrain Headache for Computer, Gaming, TV, UV Glare

I just received my glasses and put them through two stress test. First, I'd like to say they surpassed my expectations of blocking blue light. One test was with my reef aquarium growing Radion XR15w PRO full spectrum LED light fixture. It includes 4x CREE blue, 4x OSRAM deep blue, 4x CREE cool white and 9 other led lights with colors ranging from green to indigo UV. By testing the full wattage of blue, deep blue and indigo UV, these glasses filtered out almost all, if not all, blue light. Very impressive. From photos provided, one shot is from iPhone 6s' new 12mp camera (no filter) pointing straight-on aquarium. Very blue. The other aquarium shot is with the Swannies' lens upclose and covering camera while taking the picture. No blue. This light fixture setting is to provide maximum "morning" sun output for high coral growth. The second test involved shining a 200 lumen LED flashlight directly at the glasses lens to question it's blue light blocking abilities. It reflected all blue and blue related light to the wall (see photo). I tested my $200 UV protecting Ray Ban P's and you can see the results were not close.Im a person on the computer for proposal creation, PC gaming (intense graphics-- CounterStrike and WoW), creating marketing material on Photoshop and ESPN reading coupled with a Sony XBR Ultra HD TV watching Inside Out, and the likes, with my wife and little boys. Don't forget about last minute catching up with Instagram, FB, last minute fantasy football lineups and the 10 o'clock news while in bed. My life is usually in the fast lane, like many others, and my sleep is very important, especially for someone who uses a Cpap machine for sleep apnea. Having the amber lenses on these glasses provides the protection I need without losing visual brightness. I did not like the normal yellow blue blocking glasses as they did not provide much blue blocking. After testing these glasses I feel reassured that my body will start producing melotonnin at regular levels and hopefully they'll take care of my headaches as well. From what I gathered so far I give these glasses a very big two thumbs up for blue blocking abilities, without hindering visual, and and a plus for style. Sleep is vital and worth the cost of these glasses. I have no affiliation with this company and I did pay full price. I'm just a concerning parent adjusting to the new ways of life while technology tries to fix this new growing problem.

Great glasses and purely the best blue light blocking glasses there are out there. They're inexpensive and fulfills its means. If you're looking for a pair of blue light glasses that works and is not a fashion-brand with half-assed lenses, look no further. I've been using these for approximately 2 weeks everyday since purchase to reduce headaches and eye strain while looking at monitors and I must say it works. I was quite skeptic about purchasing glasses such as these but was instantly happy with the results that is not inclined by wishful thinking. The build material is what you could expect for the price but are slightly still durable if you don't stretch, drop or meticulously strain the glasses itself. For users wanting to use these with headphones, I would recommend adjusting your headphones 2 or 3 sizes bigger so it doesn't push against your head. It sometimes does this creaking sound of the plastic when you stretch it a little bit too far but is to be expected. Needless to say, they are also quite fancy and I have personally received comments on how 'cool' or 'awesome' they look with the orange lenses. Everything is perceived in a orange-tint colored fashion and is also to be expected knowing its blue light blocking effect. Works very well for normal use on smartphones, computers or tablets. I would not recommend these for editorial software or entertainment such as watching movies or photo/video editing as it will distort your sense of colors, hence not to be used while using any design/edit software. However, I would strongly recommend these if you use this for normal activity on the computer such as internet-browsing, reading under various lights, writing documents and even playing games that are not graphic dependent (such as single-player games or atmospheric games). If I had bad eyesight I would even recommend the pair that you put on your current glasses as it would pose to be a very helpful tool in your everyday life, knowing that we are affected by 'blue light' from all kinds of sources. 5/5 stars and would purchase again or recommend to friends and family. Great job Swanwick Sleep!P.S. The 7-day sleep handout link for a free e-book does not work. Not really important but interesting to note.*Note the reduce of headaches and eyestrain.

Several have posted that after a few days or more they noticed the difference in that they slept better. I noticed the difference the moment I put the Swannies on my head. What I noticed was an absence of eye strain that I wasn't even aware of before I received this glasses. I do all my computer work and TV watching now with these glasses on. I don't know how else to describe it other than to say that my eyes feel more rested when using these glasses. Sure, it is just anecdotal and only my experience but I would definitely recommend them to anyone. As for fit: I started to purchase the "Large" glasses originally, but instead got the regular size and they fit just fine. The metallic hinges on the glasses are spring loaded and so the glasses accommodate to the size of your face. As for the color differences when wearing these glasses and watching TV... well, for me it just isn't a problem. Humans can rapidly adapt to a lot of changes in life and this one was a snap to adapt to... no problem. I spend way too much time ( 6 hours or more, sometimes lots more ) viewing a computer screen daily plus TV time as well. I feel confident that these glasses are providing much more than just better sleep. My reason for purchasing them was my concern over the exposure to blue wave light and how that might be contributing over time to macular degeneration. I can live with less than perfect sleep, but not nearly as well without my vision. As for the sleep issue, I haven't noticed any problems going to sleep when I have used these glasses, but I use them during the day as well and they have not lead to any daytime drowsiness issues whatsoever. Yes, anecdotal only... but that's my story.
