FRETREE Blue Light Blocking Glasses How Does Blue Light Affect Sleep? After sundown, the lack of light signals our bodies to start producing melatonin, the hormone responsible for making us fall asleep. But today, we're exposed to light all day and into the night. Blue light waves can be especially problematic because they keep us alert. What Are Blue Light Blocking Glasses? Blue light blocking glasses have filters in lenses that block or absorb blue light, and in some cases UV light, from getting through. If you use them while looking at a screen, especially after dark, they can help reduce exposure to blue light waves. Should I Get Blue Light Blocking Glasses? The idea is that this helps break your focus from your screen, allowing your eye muscles to relax and stave off eye strain.

I'm surprised how much I like these!
As someone who's heard about blue light filtering glasses, I never thought I'd enjoying using a pair so much. I do a lot of work on my computer daily and definitely notice that eye strain and headaches are what I can usually expect. Anything that helps gives my eyes a break is much appreciated, and these lenses do just that!The black frames are nice and simple, and the glasses are so light weight that I don't feel the need to adjust them throughout the day or take breaks wearing them. I really like that the kit came with a case, cleaning cloth, blue light laser, and a blue light sensing card (allows you to see first hand how the lenses filter the blue light). It's going to be so easy to toss in my bag and take with me anywhere when I'll need to put in some long hours of screen time. I think it's definitely worth giving a try and see if it helps you.

You won't be disappointed!
These glasses are great! Not only did I use them but my 16 year old computer/ga!omg son tried them!! We both think they're very nice! They are light weight, look good and filter blue light perfectly!You won't be disappointed if you try them!The frames are made of a lightweight plastic instead of the heavier acrylic.I wear prescription glasses, but even still these for over them and they still work!My son asked if he could use them all the time!

I was skeptical
These glasses were a pleasant surprise. I suffer from migraines on a regular basis. Using mobile devices has only made them more frequent and I sometimes have to stop the work in doing because of them. I gave these glasses a week and I have noticed a difference. They are VERY lightweight and don't look terrible on my face, but the best part is that I can wear my own glasses under them so that I can still see at a distance. They are clear lenses, but you can see a very slight color difference when you take them off. It's not a noticeable difference while on your face, so colors are the same. I have a small face and they are a little big for it, but because I wear them over my own glasses on grateful for the size. Give them a chance to work for you.

Stylish and protective!
Your browser does not support HTML5 video. If your job requires you to stare at a computer all day long or if your always gaming at either your PC/laptop/TV/mobile phone, then your definitely going to want to invest in one of these. Staring at blue light is harmful for your eyes, putting these on makes a huge difference in fatigue and clarity on the screen. I love the frames, they are super stylish and I look like a professional wearing them. I like that it comes with a free carrying case, screen wiper, and blue light tester card.

Description seems somewhat inaccurate
I received a test pair to review. This was pretty convenient since I was looking to buy a pair of blue light blocking prescription glasses from Eyebuydirect anyways to see what the hype was about.The blue light blocking effect isn't quite as significant as I was led to believe. The pictures I have attached show the results of 2 seconds of blue light shined on both the left and right side of the provided testing strip with the provided blue LED. It's clear that the glasses do block some light, but 95% of blue light might be a stretch.I can also confirm that these lenses block UV light. I neglected to provide pictures as it is difficult to hold a UV flashlight, glasses, a dollar bill, and a phone at the same time. At any rate, the glasses block the security strip on the dollar bill from glowing.As for using these glasses while on the computer, the effects seem similar to using the free F.lux program. Everything turns a yellowish color. While I'm not completely sold on the benefits of blocking blue light, these glasses seem to represent a good value if you are looking to try it out. For comparison, the Eyebuydirect prescription glasses start at $25 as of 11/13/2019.

Nice all black frame
Honestly i don’t kNow if these do anything to relieve eye strain. I’ve tried them a few days now and in all honestly, on or off there really isn’t a difference for me so far.But what i will review is the glasses itself. They came w a nice case, fiber cloth, and a testing kit to prove it really does block blue light. The frame is super light and comfortable to wear. I tend to have issues w frames fitting my face as i think i have a large head/face, but i was pleasantly surprised when the frames fit me just fine (got size L/xl). Also liked that the frames were unisex versus most of the other brands available on Amazon seemed more feminine looking.All in all I’d say give these a try if you’re interested in this kind of eyewear. Verdict is still out if they actually work for me but for under $20 It was worth trying

Effective and much cheaper than "commercial" blue light glasses
These are made entirely of plastic and probably cost very little to put together BUT they work(using them right now as I type on my phone) are very light weight and are surprisingly durable despite(because of??) being all plastic. The plastic limbs are just soft enough to bend into all kinds of shapes without breaking and with going back into shape afterward. Since these really do help significantly with computer screen glare(blue light?), I cant ding them any stars for being plastic. Youre paying a much lower price because these are made of plastic. So comparing these to their price point and to more traditionally constructed, "name brand" blue blocking glasses, these are totally appropriate and reasonable for what they cost. I always hate it(or laugh) when someone buys the cheapest product they can find and then complain that it's not made like the more expensive versions. These are great for what they cost and will last me a looong time since I wear them at my computer desk and put them in their case when I'm done. These dont look all that unattractive either, although very few folk will see me in them lol
