Clip-on Blue Light Blocking Eyewear

Both types of lenses are now part of my day. The two lightweight but strong lenses do a superb job! The clips that fit over bridge of glasses are strong but flexible, will not slip off and easily cover my small glasses. (see photo) For the glare of computer screen (which I use much of the day), the Blue Reducing light yellow lens takes effect immediately. I was quite surprised at the dramatic end to sharp stinging eye pain I usually experience. And, I can do so without dimming the screen! The Night Time clip-on lenses to wear two hours before going to bed helped me to wind down my day, and I could actually feel ready to fall asleep in that time. Without them, I tend to stay up too late and find it hard to get to sleep. The lenses each come in light but sturdy protective containers to fit securely and snap closed. Both drop into soft bags to hang on nearby walls in office and bedroom. However, I keep my computer clip-on in place, ready to go. What a difference in taking best care of my eyes as I head into macular degeneration and need to take even better care of my eye health! Great value - only wish I had started using them years ago. Thank you to the Spectra479 vendors for offering such fine quality.

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.

This is a fantastic product. Could not be more pleased with the purchase. Everything about it stands out. I hope the vendor who produces and sells them is doing well. I purchased a long time ago and should have given a review then but I have had them for a long time now and used them routinely so its better now. Sounds silly but everything about them was impressive. The plastic case came in a silky pouch that can be used to actually clean the lenses. The case itself is sturdy plastic that protects them perfectly and holds it tightly so they don't rattle around. The way they attach to the glasses is very well executed, as in they don't just slide over but have a sturdy spring action that makes certain they stay snug and never fall off and go on easily and then THEY WORK! I remember when I received them there was a little note that said they were a small family business so if I could give a review it would go a long way. It was one of those....oh I really ought to do it thing you don't end up doing but here I am by chance and feel compelled to do as I thought I should some time back. Hope their business is doing great and I would buy again except they still work perfectly after a few years and I STILL HAVE THE CASE AND THE LITTLE POUCH THEY CAME JN

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.

This is a great item to relieve your eyes from fatigue with blue screen.. when I watch TV with these on before I go to bed ,I sleep better and easier to fall asleep. I only have the amber color so it changes the color on your screen. Never tried the clear ones. I bought one for each of my family members.they are clip on so they fit perfectly over my eyeglasses.

I almost didn't order due to price.. I bought the dual pair pack and I'm SO glad I did!! They are straight up Quality right out of the box! When you put them on you KNOW they are quality. It's the difference between non-polarized sunglasses and Polarized.. you see the difference. I'm so glad I bought these. I've been wearing the daylight ones all day. I love love love them both! I was born a night person. I have such a hard time not staying up until five in the morning. I often have to stay up all night, sometimes a couple of nights trying to reset my body clock. I naturally want to sleep between 6am and 2pm. But it makes it very difficult when the rest of the world is not in my time. My day never really begins until 3pm. So I'm trying to block all the blue ray's I can to see if it will help me to be able to go to bed by midnight and actually fall asleep instead of laying there for hours and then giving up. I bought these, blue light blocking lightbulbs for my bedroom where I spend most evenings, and purchased s sunrise clock. I mostly bought these for television to block that.. they should come with blue light blockers like my phone. But they don't, so I'll try this. I totally forgot I even had the daylight lenses on! The night lens are gorgeous, I have no problem with the change of color! So pretty! They come with a hard case and a drawstring bag.. very nice! I was impressed with the packaging and inside note from this family owned business. You can't go wrong. Well worth the price. I will take very good care of them! They fit my glasses perfectly! I hope they get to making them in many shapes for different lens shapes! Is it weird I'm so excited about these!!!? Lol Buy them! You will love them!

I have been developing vision problems and it's been worrying and distressing me very much the past 6 months. I finally got a clue it could be damage from blue light. (Too many years of daily work on laptops, no blue-light screening.) I've been avoiding looking at my screen a few days, feeling I'm really at a crossroads with my vision, and waiting for this product. I put them on immediately standing in the Post Office. It was a very gray, overcast day outside in the north. Not a bit of sun. The days when it's HARDEST for my eyes to see clearly. Soon as I stepped outdoors my vision was amazingly better. Things seemed brighter. I could make out so much more. There was a sort of orange-yellow glow everywhere, like at sunset time. It was so strange, because I took them off to compare and it was suddenly murky-dark out there again. Quite a miracle. Blue light must be everywhere, because filtering it, even headlights of cars look yellow or green. I wondered how it would be on my computer, where my eyes have been struggling so much lately even with lots of Vitamin A and foods good for the eyes. I found I could read everything easier and better, and it was not necessary to increase the brightness of my screen. I am so grateful to these people. The box it came in gives helpful information about the problem of blue light, and the glasses, things I didn't know. Another thing: With these on my eyes feel immediately more relaxed, whether inside or outside. I had no idea the strain my eyes were always under. The glasses (clip-ons) are described as a method of improving sleep. I will be looking forward to that. But right now the way they simply improve vision and make it possible to keep working on my computer (without going blind) and maintaining my livilihood -- is is a plenty big boon. The way I feel right now, these simple clip-ons are saving my bacon and my whole life.

I love the tint on these "nighttime" lenses. They are perfect sunglasses for any bright conditions. And they have no polarization which is strangely hard to find. Unfortunately I can see the clip in my line of vision so I need to return them. Also to the manufacturer: maybe you have the use case of these tints reversed? Yellow tint is better for off-setting blue light from screens. Orange tint provides the best sun shield and the best visibility for bright outdoor daylight.

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

パソコン使用時間が長いので目の疲れが軽減されて助かります。少し黄色がかっているけど使ってると気にはなりません

The lens quality is good, they do not cause distortion compared to other ones I tried before. They don't flip up and down, but that doesn't matter to me, I actually prefer that because the clip-on is lighter and less bulky than those that flip up and down. I like them so much that I bought 4 pairs of their glasses to give to my kids and grand kids.

I work a desk job that requires me to stare at excel sheets and documents for hours with multiple screens, the clip on lenses have been a game changer for me, be it at work or at home. Blue light toxicity is a real thing in our digital age where all eyes appear glued to screens be it toddlers or seniors . . overall i am satisfied with the product and highly recommend it for others as well. I have personally used clear lense "blue light blockers" but after using these lenses from spectra, i know this is the real deal.

After a few weeks of using this upon receipt, I feel it has been money well spent. My eyes thank me (and this) for feeling less strained and it also belongs to my arsenal in (long term) improvement of my eyesight. I have had no problems with the clip-on yet. It can feel a little flimsy but as long as you are careful with it (which you should with any item of value), I think it should last a long time. Even if it has to be replaced, I would think at the price point, these are very good value blue light blockers. Thank you to the creator and he even included a hand written note to thank you for the purchase. Nice touch and authenticity. Please keep making good products! Highly recommended.
