With description and sales points having grammar and shortage of using spaces. I almost did not order this because of that. It reads like it went through a translastor. I went ahead and ordered because of the great reviews (now I see that they're all less than 6 weeks old). I was suckered into bait and switch con sales game.Description does not point out that these are 139MM, my preference is 150MM so these dont reach far enough back.Packing List says a blue light test is included and then says right after that, it may not be included.The blue light laser I received was not the one pictured. So what you see in the items pictures may or may not be what you get.And I see that another reviewer got a different laser than the picture or myself. She also got an American flag pouch, I didn't receive a pouch, but that was not on the packing list.The laser tester, be very careful with it, mine looks the exact same on both ends and there's no indication on how to properly hold it. If you accidentally turn it on and blind yourself, it could end up with eye damage. Definitely dont let children be around this. Its bright, it hurts the eyes when testing.The interesting part is I have prescription glasses for distance. Their "test" says those fail. OK, I try 3 other people with blue blocking lenses in the office. They all fail this "test". Yet we can see the blue sheen on their computer glasses that indicates they have a blue blocking coating. These have a green sheen. What exact spectrum does this laser puts out? Who knows. One has to question that this "test" "proves" when it comes from a seller and not a independent third party. This is snake oil. I got suckered. None of this is certified. Classic bait and switch. In my opinion, they are complete fraud.Edit: I was bot spammed by the company asking if I was happy and to leave good feedback. Obviously this caring company does not value my feedback or they dont read english. Their spam email struggled with English grammer. They only care about getting good feedback.I do not have an answer for Blue Light blocker. My opinion is the company is only to sell un-certified claims.On the green side. The cloth I got did nothin other than smear oil on the lense. Thankfully I had other cloths. Case... Cheap plastic case, do I really need another? Frames? Dollar store quality. If you want to be green. Avoid this product.Very impressive for a to z.... Very fast shipping (I got it on Sunday Dec30, order on Fri Dec28!), even Holiday period.Plus, impressive stuff with the glasses: (watch my photos as evidence)1. The glasses: Good looking + strong + true glasses (not plastic) and clear (not yellow = it is for driving only!).2. Wonderful screwdriver. Always we need with the glasses and only this company give. Example: I bought a very expensive Rayban, they never give me!.3. The silicons for the nose and ears (perfect).4. The Test plastic card with the laser: As Evidence, it is not a fake UV glasses.5. The size of the hard box (not a cheap).6. + the USA flag pouch!I am very very very happy and I talk around me because you are the BEST.HIGHLY RECOMMEND,Your very happy Picky CustomerI begin very well in 2019!HAPPY NEW YEAR MY FRIENDSLONG LIFE TO YOUR COMPANYI decided to buy a pair of these blue light blocking glasses because I spend a lot of time in front of a monitor (avid gamer) as well as TV. When I received the package, I was surprised to find some extras. A blue light pen and a test card to show how the glasses work. A frame adjustment tool and pads for both the nose rests and the ear rests. Sweet.Very Light weight frames. I bought this pair because I am on the computer all day and wanted to try. After one day I can tell the difference.These glasses are so cute! They’re lightweight and I really like them! I wasn’t sure what they were for but I haven’t had any more tension headaches!Nice and light weight. I even like how they look. Cleaning kit was a nice surpriseYes i recieved them and they are as discribed. Wonderful. ThankyouGood for those looking at screen a lot.
