Yes, quality.
I really do think these help with night time reading your phone in bed, to lessen the blue light waking up your brain! Clip ons are great for those using prescription or standard reading glasses. Would buy again and have suggested them many times to friends for the same reason. Quality is very good and they do no harm to your glasses.

All pros, no cons and no regrets
For others like myself who refuse to follow the medical recommendation to turn off the TV [or phone] an hour or more before bedtime, these are game changers.I want to watch TV using my prescription lenses, so I specifically wanted a lightweight clip-on solution. The spring-loaded clipping mechanism works fine and should fit over lenses approaching 1/4 inch thick. It’s too soon to know, but I hope it will continue to work through many on-off cycles in the coming months and years.Note that these do not ‘flip up’, which I perceive to be a positive. I didn’t want to pay more for that feature; I don’t want extra parts adding weight and being something else to break; and intermittently seeing blue at night seems to me to defeat the whole purpose.I just watched a video by a scientist who claims that blue-blocking lenses need not wrap around the side of your eyes. Blue rays in your peripheral vision are an almost insignificant part of the nighttime problem. He alleges most of the receptors of interest are located in or near the retina. I conclude the clip-on solution is sufficiently effective for my purposes.These lenses appear to be made from the amber-colored material. I see no evidence that these are clear lenses with a cheap colored coating as I’ve heard is the case for other similar products. It’s too soon to tell if these have any scratch-resistance, and I probably wouldn’t have wanted to pay extra for such a feature, but I intend to handle them carefully and then faithfully store them in the nice case they arrived in.Somebody somewhere is going to complain that blue-blocking makes things “look weird”. So does taking Sildenafil where everything looks blue. So does scuba diving where the reds become undetectable. It’s not a matter of clarity – the lenses seem flawless – it’s what the world looks like without [the majority of] blue color. The benefits are worth the effort to adapt to things looking this way for an hour or so at the end of each day.I didn’t want to invest a bunch of time right now researching the science behind this – I just wanted to block a huge part of the blue light spectrum and see if I could improve what my sport watch has been telling me is ‘poor’ sleep. The results from the first night were promising, but I knew it was entirely possible that other factors could be responsible. Several weeks’ sleep reinforced the first night’s findings – these lenses definitely improve what my watch detects for sleep quality, and there’s no question that I fall asleep almost immediately now.This is a well-made product that performs exactly as needed, purchased hassle-free, and delivered promptly. I think the value of improved sleep for this price is exceptional. I would highly recommend Spectra479 lenses in any form factor from Zendustries.

Quality, easy to use solution to blue light blues – fragmented sleep
I decided I really needed to get serious about sleep. I had been falling to sleep OK but waking up 30 to 50 minutes later; sometimes repeating this a second time before I would settle into longer sleep segments. I had been focusing on things like caffeine and getting a better pre-sleep routine then it occurred to me: I have a bedtime routine alright but the routine revolves around my laptop, iPad or iPhone reading digital news, catching up on sports scores, reading a digital novel, that sort of thing. I was completely overlooking the blue light issues that accompany computers.I waded into Amazon and settled on these clip on glasses, handled by Spectra479 Biorhythm Safe Lighting. I had never heard of product nor company. They were both superb. I got them quickly. The clip on system was easy to attach, firm and fit well. They came in a well designed plastic case and the shipment also included a soft smooth bag to protect them outside the case. I leave them attached to glasses I wear late evening. I can easily shift from reading my iPad to brushing my teeth using these glasses. I quickly note that things that should be yellow are clear when wearing glasses. This is a non issue for 99% of things I do during that last hour or so before I turn out the lights. The science behind the “blue light” is another matter. I am just telling you this product has earmarks of quality construction and thoughtful customer service. There are very inexpensive. Get them

Functional and straightforward, seems to work.
Decent product. Does a good job of filtering blue light, at least as far as I can tell. They clip on and stay on easily enough. Perfectly functional even if they look a little weird on my own pair of prescription glasses.

How’s this for cool!
They arrived today, the packaging was awesome, very upscale, durable. I’ve been wearing them since about 6 this evening, so far my eyes are not stinging, they don’t feel sticky and tired. I’ve been staring at computer screens for the last 6 hours non stop, by now I usually am rubbing my eyes a lot. I don’t know how this is going to effect me long term, if I can remember Ill come give an updated review in a couple of weeks. On first try though I am very impressed with them. Oh and how’s this for cool…in the package was a hand written sticky note from the manufacturer, I am so happy about this purchase, Ill likely be purchasing the day time ones as well. Im really interested to see how these do while Im driving, if they can help tone down those brighter than need be headlights people keep blindin me with!Heres the update: Its been nearly 10 days since I started wearing them, no gritty eye, they don’t even feel tired, my body is tired from the whole being awake at night thing but not my eyes. I don’t feel like there are 10k needles poking my eyelids when I blink, no headache, I think less overall tension in my eye/head area. Im not squinting to try and keep my eyes from being flooded by all the brightness. I work nights and I have to stare at computer screens a lot but there is no bloodshot or even irritation going on. So yes, still a winner, matter of fact I think I just talked a co worker into buying some. Thank God for talented people who make good products we the people can use!

Hola amigos, quiero reseñar acerca de estos lentes….Yo presentaba mucha irritacion en los ojos , siempre estaban secos, con vision borrosa, afectacion en la agudeza visual con varias dioptrias, y con molestia en general que la atribuia sencillamente a un estado precario de salud ocular…….usaba otros lentes de otro fabricante que supuestamente detenian la emsion de luz dañina, asi lo creia yo pero…… !! SORPRESA !! Empiezo a usar siempre estas gafas milagrosas al estar en la computadora y al ver mi celular y en cuestion de UNA SEMANA mis ojos se sienten mucho menos irritados, la resequedad se fue por completo, ya no tengo vision borrosa y ademas veo con mas agudeza…….TODOS MIS PROBLEMAS LOS OCASIONABA LA MALDITA PANTALLA DE LA COMPUTADORA Y DEL CELULAR !!!!!! RECOMIENDO UN MILLON DE VECES A TODO MUNDO QUE USE ESTAS MARAVILLOSAS GAFAS SI TIENE LOS MISMOS PROBLEMAS QUE MENCIONO, SON FANTASTICAS Y ESTOY MUY FELIZ DE HABERLOS COMPRADO

They clip easily onto my prescription glasses. I use them for night driving and when I’m on my phone at night or looking at screens in the day

They literally block 100% of blue lightThey are best used at night before going to sleep, for people who are weak to blue lightBecause of how strong they are, I wouldn’t necessarily recommend them for all-day usePictures show with/without the lens
