K KENZHOUBlue Light Filter Clip-on Computer Reading Glasses UV Blue light Anti Eye Strain Unisex Anti Blue 2 Pack

I had been having trouble sleeping, severe eye fatigue and worsening vision and I was searching for something to protect my eyes since I am on the computer or phone about 10-18 hours a day. I was leery of sticking a screen protector to my PC to block the blue light so I was happy to find these.These have a very slight tint of an amber color and are made of a reasonably sturdy material. I find them very comfortable to wear although while looking down they tend make my glasses slide down my nose. They do not distort any of the colors in any significant way which is important since I work with art and photography and need to see colors correctly. The only thing that maybe an issue is there seems to be some very minor marks on the lenses where they sit up against my glasses.I wear these all day long and find that they are more beneficial than the PC screen protector would have been since I can look from on device (PC, Smart Phone or TV) to another with ease. I have been sleeping much better which has made me more productive while working and my eyes are not so sore and tired.

This is my second time buying these because I got new glasses with a round frame. They fit almost perfectly, others don't usually notice it. You can see the difference with these on and off, but the yellow tint isn't extreme. It helps me greatly with eye strain as I often spend hours studying on my laptop. And 2 for $20 total is a good deal.

A lot of the reviews state that these do not really filter out blue light, or they are just not effective at doing so. I have not noticed any difference, but I have not been wearing these long enough. There was also a concern about scratches on prescription glasses, but I haven't noticed any besides the scratches I already have on mine. It's pretty easy taking it on and off, which I like, but the glare on them is absolutely insane. If you're not looking directly at some ungodly bright light, you'll see your own face reflected inside the glasses 24/7. I wish I could wear these around the house, but the glare stops me from doing that. Overall, I'll end up keeping them, so hopefully it reduces my eye strain and headaches.EDIT: I have tested this at work where I stare at a screen for 7 hours a day and it’s pretty nice. By the halfway mark, I am usually nodding off with a headache, but with the glasses, it seems I have much less stress on my eyes. The glasses are tinted a bit yellow so it reduces the whiteness of the screen, so it might just be that.

I've got to accept on faith that they filter blue light. So, I looked for features. These are described as "Clip on" and Flip up." They do clip on, but they don't flip up. I can live with that, but the seller should correct the description. Not included in the listing, but included with the package are rubber replacement cushions for the clip. I assume these are to protect the lenses of your glasses and hold the clip in place. A nice thought and pleasant addition.

I bought the 2-pack. My boyfriend and I both use and love these. They're not too heavy, especially on my light metal frames - I don't even notice they're there. They're large enough to cover past the entire lens, and they have a little mechanism you can push at the top that makes them really easy to slide onto and off of your glasses. The change in warmth is subtle. They're not overly yellow, which is what I was looking for. I do a lot of graphic design, so I needed the colors to not look too different - these did the trick. I've been using them a few weeks, now, and I notice less eye strain after prolonged screen time for sure. Each pair comes with a slim little plastic case, and I received one cleaning cloth and a little baggie of extra rubber pieces (the rubber makes them scratch-free where the clip ons touch your actual glasses lenses).

The good:-Nice job at blocking UV light from computer/tablet screen. It really makes a difference on how much easier UV Blocking is on the eyes. Specially after long periods of time.-Lightweight-Very clearThe dad:- Really weak clip mounting that sits too low, so if your glasses have a straight bridge across the top of the lenses, the bottom part of these clip-ons will sit halfway thru your lenses. It slips off very easily requiring re-setting very often.- These are a real magnet for dust and scratches. They do attract almost anything that gets close to them and scratch super easily. I kid you not.- when the clip weakens the clip-on has a tendency to touch the lens in the glasses, which can eventually scratch the surface of your glasses as well.Nice try, but I returned them, and continue my quest for better ones.

I am very excited to share my experience. I am blind in 1 eye. I put lots of strain on it because have to use the computer for work (many hours daily). I had been getting severe headaches, pain in my neck and back. I HAD to do something. After researching the various options, I came upon these. I have been using them for a couple of weeks. No headaches. They work!!!! Better than the prescription lenses from the doctor. I paid an extra $$ to have computer lenses included with my prescription glasses. They did not work and the headaches returned. I waisted money for nothing at the eye Dr.I have recommended these as well as purchasing some for a gift. They are light weight. Clips to any pair of glasses. Come with 2 pair in a nice storage case. Won't harm lenses. Very durable. HIGHLY RECOMMEND!!!

These move around way too much

Dimensions listed in the description by the seller are exact. This means that the clips fit perfectly on my existing prescribed glasses. I also find 'clips' light. They do not bother me at all. The clips make a difference to me. My eyes do not get as tired when being on my computer or when watching TV. There is a slight glare that comes with the clips but it does not bother me at all. Overall, after 2 days of wearing the clips, I am quite happy with my purchase.

The light weight is great. The blue light shines off the glasses and others can’t see your eyes.. Perhaps the glasses do not have anti-glare? Feels comfortable but don’t look good on camera.

Just recieved the product. The box it came in was a bit dirty, especially on the inside. The glasses themselves were okay, the clip works but doesn't fit perfectly on my glasses (but it may be because of the style).

Great product! I have been wearing glasses for almost 40 years and have felt eye strain the past few months. Since the beginning of the pandemic I have heavily increased my screen time and could feel the effects. The tired strained feeling in my eyes faded after the 1st day. I don't know if it will be the same for others, but I would recommend giving them a try. I also appreciate the fact that they come as a pair. I kept one and gave the other to my child (7). The size fit perfect for both pairs of glasses and they are so light-weight that I don't even notice them most of the time.

The clip ons are great and I like that they came with a case but I feel I have to be fairly careful when I put them in and remove them. Not really a complaint just to be aware I gave the second pair to my spouse.They help a lot with easing my eye strain. I have macular degeneration and I needed some help with this. So far I like them.
