Cyxus Blue Light Filter UV Blocking Glasses [Clip On] Anti Eye Strain (Sleep Better), Computer/Cell Phone/PC Game/TV Safety Protection Block Radiation Reading Eyewear

I bought these for my 8 year old who already wears prescription glasses and they clip on very nicely. He had to get used to the colour at first but only for 5 min. I tested the blue light filtering ability with the mini kit included (Nice touch) and it seems to do the job. He clips them onto his glasses when it’s “screen time” and he told me his eyes don’t feel so tired afterwards (he gets 30 to 60 min screen time. I’m not sure about the durability, time will tell. I’m a little worried that the clipping part might break off (8 year old boys can be rough and impatient), but so far so good. Video of unboxing attached.

The clip-on filter in the description is yellow (and is thus a blue filter). The clip-on filter I have received appears to be completely clear/transparent. It does not modify blue colour transmission at all. It does, however, come with a "blue" light and a "blue"-sensitive testing sheet which turns blue when you shine the "blue" light from the enclosed "blue" light source on it. It does not turn blue when you shine the "blue" light onto the test sheet through the filter. However, the "blue" light source looks more like an UV light source to me. For example, if I look at the colour picker colour wheel on an Apple Mac OS X computer, there is no perceptible difference looking at it through this filter, or directly. And when I say no perceptible difference, I don't mean the difference is small, I mean I cannot tell any difference at all no matter how hard I try. If the clip-on filter was yellow, I would see slightly yellow through it, which I was expecting. I see no such effect. However, it does seem to block the "blue" light from the "blue" light source provided in the package (which I think means it's really blocking UV). I have no idea whether it has any effect on eye fatigue or not. It definitively has no effect at all that I can see on 490nm wavelength light (which is the green side of blue). Whether it affects 400nm wavelength light (which is the low end of visible violet, and lower wavelength than a computer monitor can display), I can't tell. So how do I tell whether I bought something that will protect my eyes or an expensive transparent clip-on attachment for my glasses? I don't know.

Excellent lenses! I’m disabled with MS and the Cyrus have been a great help. These are light, highly finished filters. They have a very good cushioned set of central flip-up grips that don’t mark your glasses. I use them for long console gaming sessions, and I noticed the difference on the first use. I easily get eye-strain and headaches, but after playing a long-ish game with the filters on there was none of the usual discomfort. The filters come in a faux-leather case with a cleaning cloth, which I hadn’t expected. Rare to see such quality these days!Only slight negative, might be that at first, the cushion-grips seem to be a little dominant in the Center of your vision, but they quickly ‘disappear’ and you don’t notice them at all. A very good product, highly recommended!

As an enthusiastic gamer who enjoys unhealthy doses of video gaming way into the night/morning, I'm only human and I do suffer from occasional headaches or eyestrain. Not enough to put me off "just one more level" but these headaches can disrupt my playing. And as we all know, nothing disrupts our game time!I have to say I do notice a differences whilst wearing these. I've suffered much less (if at all) headaches and eyestrain whilst using these. They do turn everything a slight shade of orange, although you do soon forget about it after a while. They also add additional weight to your glasses, so it may cause them to slide down your nose every so often.Whilst I don't have any scientific facts to back this up, they supposedly filter out harmful blue-light rays, which supposedly disrupt sleep and may potentially cause health issues. But if wearing these has stopped headaches and eyestrain whilst staring at computer screens, then surely it must be doing something right.They do feel well constructed, but I doubt they will survive more than a drop or 2. The lens also has a habit of catching finger marks, which are difficult to rub off unless you use those little clothes that come with glasses (although let's be honest: we all tend to just clean our glasses with our T-Shirts!).Overall, I'd highly recommend this product if you get headaches or eyestrain, or are concerned about your health.PS. It comes in a dedicated glasses case, cleaning cloth, blue-light tester (which I honestly never used) and lifetime warranty: apparently if they break under normal use, you can purchase a replacement with 50% off.

Bought these, wasn't at all sure if they would work, but I can definitely say that they do help with night time driving and they make looking at screens easier on the eyes. I use these over my prescription reading glasses when my eyes are tired as I do a lot of screen work.

Recently this Company sent me another pair as the first one had problems. I always give honest reviews and wish to review this second pair. I have used this item for a few weeks now and have to say there are no problems this time around and they have helped my eyes considerably. I spend most of my days on my iPads so I really can tell the difference. All products we purchase can develop a fault but I’m really glad to have been given the chance to try this item again. The glasses are very effective and I will be purchasing another pair for my other glasses to save switching over.

Having learnt how computer screens and digital tv's emit blue light that damages seratonin , eyes and disrupts sleep patterns I decided to invest in some clip ons for my spectacles whilst working on my laptop and gaming on my tv .item arrived in soft leather case with cleaning clothAND a protective pouch . Also included was a blue light test card with blue light torch which actually turns blue when torch shone on it , but doesn't when lenses placed between . I am impressed with the quality and with presentation and did not find it intrusive to my viewing . Considering the reasonable price I highly reccommend this product .

Great product with no issues. Some reviews had said the clasp was flimsy and difficult to use, however I found it plenty robust enough for daily use and very easy to use. The attachment part needs to be small to be light and not block vision. Bear in mind that these will increase the weight of your glasses and therefore they will slip down more easily. Also I don’t think they would work with the style of glasses that rest directly on the bridge of your nose. Much better with the type of glasses with wee legs and nose pads that rest on the sides of the nose. Did they make a dramatic improvement to my sleep? No I don’t think so. I’ve stopped using them now, but would use again if sleep deteriorated, as part of a range of measures to help. They can’t do any harm.

I've been having trouble with headaches and eye strain (especially being dazzled by brilliant white headlights) been wearing them today to do my tax return and drove with them and I feel great, by now my eyes would be really sore. Only thing is I can tell I've got heavier glasses on the bridge of my nose... But I'm very pleased.

Clips onto my glasses easily. Comes with a test to show hard blue light is filtered out ( of course ordinary glass is opaque to uv light so the test provided is not really necessary, however the lenses may filter out a wider range of frequencies). I am not sure yet if use of these filters make getting to sleep easier, I am still experementing with how long before bedtime to start using them.

Work very well. My eyes feel so much better now. No more eye ache, dryness, itching etc. and I am less tired as a result. Compared to new glasses with the flyer costing, these are a lot cheaper until I need a new prescription.

I watch several hours of television on a big screen just before sleeping, and often have trouble dropping off. I bought these as an experiment, and I find they really work. They clip on easily over my glasses, covering the whole lens, and don't obscure my vision for anything else including fine needlework. I readily fall asleep when it's time now.

There mmm ok , I was hoping they might help the glare in night driving but it was a no no ! I also find the clip on bit is distracting in ur viewing ( to big and bulky, I really should Ov sent them back !

The only problem with these (for me) is that the clip on bit is too narrow for my glasses so they end up sitting high. This then means that my glasses are unstable (It's difficult to explain the geometry). You need to be brave, and careful, enough to bend the clip on bit to suit

These work very well and my eyes feel so much more relaxed when working on my laptop in the evenings. I think I sleep better too.
