Clip On Blue Light Blocking Glasses - 14 Lens Types | Clips over prescription frames. Filtration from 35% clear for daytime screens to 100% red for sleep.

I love them- they are easy to slip on and off my glasses and easy to clean!

These work great.

Pros: good quality lens. Especially useful while driving in dim light and at nite. Contrast & sharpness of visual field markedly improved. Oncoming headlights appear slightly yellow. Easier on the eyes. The lens covering size is nearly perfect; just wider overall. Important measurements: distance between lenses at bridge, abt 9/16"; distance between outside edge of rubber feet grips abt 1 & 1/8". Tension of grips, okay. But do move easily. Using mine on rimless glasses. Comes in nice carrying case. Cons: the lenses are wider than my glasses by abt 1/4" on each end. But not a functional problem. These lenses do the job.

Good stuff! The coronavirus lock down had me staring at a computer screen for months on end now and I could tell it was taking a toll on my eyes and sleep. I had heard in the past about monitor glare and blue light problems in the past, but I guess because I never was around screens for too long it wasn't a problem, but during the lock down I was on it for almost 10-12 hours per day. I am typing this review after a few hours. I noticed immediately the effect on my eyes. Felt MUCH better and I imagine it will keep improving after wearing them over the next few days and coming weeks. Felt MUCH more relaxed too, could feel all that sleep I had been missing come back. So much so that I am going to take them off probably now and wait till later tonight before bed to put them on, then once my sleep pattern returns to normal, Ill wear them throughout the day to keep my eyes from getting too strained and follow that pattern of putting them on right before bed (as they recommend on the box and card inside!). For anyone worried about the color, it adds a SLIGHT tinge of amber/orange to the screen, but you can still see colors (blue, green, red etc.). You can make out colors, it just everything has a slight tinge of amber/orange. BUT wow, the screen looks crisp. The words/text, images everything is very crisp/clean looking. I plan 100% on bringing this back to the office in the future, don't have to stress or strain to look at the screen even when typing these small letters. For anyone worried about the size, it completely covers my glasses with some spare edge remaining. Good product, I rarely review products on Amazon, but this I could notice immediately and felt really good!

So the measurements are correct, unfortunately the engineer did not set these up to be flush with the lenses. So the blue light blocking lens sits higher and doesn't fit my glasses, letting in the blue light at the bottom of the lens. Not to mention if you're a movie buff this will turn everything orange and ruin the quality. These are probably great for people that sit in their beds and stare at their cell phone or read a Kindle and aren't worrying about color quality.

Love these! I bought the clip on for my prescription glasses and they are very easy on and off! After a few minutes you don't even notice you are wearing them! Would highly recommend! They also come with a case to use. I can fall asleep much faster!

I am so grateful these night-time blue light clip ons came The Day After I Ordered Them!!!! And.... They Are Terrific! Better Than I Hoped For! I worried about whether/how they would fit on my frames. They fit perfectly on my 1/8" thick frames., and they completely cover my lenses. Plus, the mechanism that keeps them on my frames is very well made and uncompromisingly durable - it will last as long as I don't do something stupid like step on the clip-ons (it has happened). And, They Are Comfy! I am so pleased! And finally, They Really Work So Well! I suffer from dry eye and insomnia, and these night-time blue light clip ons have improved my dry eyes ...And, I am finally able to fall asleep. It wasn't enough for me to use the Flux and Night Time apps on my Apple laptops, iMac, and iPhone. Moreover, day time yellow blue light blocking glasses and monitor filters still did not help me sleep. Now I can sleep!!! I mean, I really have had terrible insomnia, so much so, I had to stop using my computers/devices by 4:00 pm if I was going to have a chance at falling to sleep, even after cutting out caffeine and following every possible sleep recommendation out there. So Thank You SLEEPZM - you have improved my life! I am forever grateful for you making such a quality product that you stand behind.

Great for nighttime to prevent sleeplessness. Easy to apply, and stays on fairly reliably. I am still able to read well at night with these glasses under a bright light. I tried other clip-ons but they readily fell off!

I purchased this glass on the recommendation from my friend that blue light is bad for my eye, since I work in front of the computer for long time. It does make my eye feel better. But another benefit is that after wearing this clip, I noticed that my REM period during sleep (as measured by my Fitbit sense) increased significantly. This is has been consistent for last three weeks since I wear it. Therefore, I would think that the improvement of REM stage is caused by this glass. So it does improve my sleep. It is a little bit heavier than normal clip on. It fits my glasses very well. I recommend this for anyone.

四六時中パソコンを使用する夫用に購入しました。 目に刺激が少ないようです。 肩こりや、眠りが浅い時があるという事だったので、それを治したいと思っています。 まだ、結果はわからないですが良い感じがするのでこのまま使用していきます！

This is the best thing happened to me. I had started a problem where I used to feel uncomfortable with white light emitting from computer and then gradually I started developing swollen eyes and eye bags after the computer usage. and I tried buying good monitor, crizzal glasses etc but it did not solve the issue. I tried this glasses and it worked wonders ... All my problems gone in one go. I can't thank enough to the creator of this glass. Thanks this product really worked on my problems. Note : I am working professional and work 10-12 hours on computer. And recently started seeing dry eye, eye bags, swollen eye issue after EOD I used to feel lots of pain around my eyes. And when I bought this clipon it worked like miracle. Thanks

Handy to use with my prescription glasses.

good to use.
