Spectra479 Clip-on Blue Light Blocking Eyewear

These blue blockers really work from the first night. During the last 2-3 years, my sleep cycle has been disrupted. It has been hard to settle down at night, and no matter what time I go to bed, 5-6 hours of sleep was all I could get. I started using the Spectra479 nighttime clip-ons for about 2 hours before I want to sleep. I continued using my computer and phone as usual and felt a pleasant, normal sleepiness around 10:00-10:30 pm. I keep the blue blockers on until I get into bed and take my glasses off. I've been able to sleep a full 8+ hours and wake up extremely refreshed. Highly recommend! The clip-ons are well made and easy to put on and off my Rx glasses. The included plastic case is convenient and protects them well.

I love these Spectra479 Clip-On Blue Light Blocking Lenses. I recently had cataract surgery, and my doctor emphasized how important blue light protection is during recovery, especially with screen use. These clip on securely to my glasses and don’t shift around, which makes them easy to wear all day while working. I’ve already noticed a difference — less eye fatigue, less dryness, and I don’t feel as exhausted at the end of my workday. That alone makes them worth it for me. They’re comfortable enough that I plan to keep using them even after I’m fully healed. The only small thing to note is lens height. My glasses are on the larger side, and these lenses are slightly shorter, so I can’t see as clearly if I look sharply downward. For normal day-to-day use, though, it hasn’t really been an issue. Overall, these have been a great addition and really helpful for reducing screen-related eye strain.

These are the best for blocking blue light at night. I work second shift and I put these on over my glasses at sunset. It has significantly improved my headaches, ability to fall asleep and my overall vision has improved. I have purchased multiple of these for myself, my husband and family members and have recommended them to countless people. I have had no issues. They work perfectly and block more blue light than other glasses I have tried.

These clip-ons appear to be very effective in blue light blocking. I've only used a few nights but I do believe it is already helping with my sleep patterns. I've only really used the nighttime so far about 2 hours before bedtime and I seem to be waking up less during the night and getting into a deeper sleep. I tried the daytime lenses and they are pleasant to wear and do not affect your ability to see clearly. Time will tell if this is a long term solution; I had suspected my exposure to electronics all night started to affect my sleep negatively. These clip-ons (both day and night versions) are pretty well constructed and high quality and would fit a variety of glasses but not all. The shape and size luckily fits my own glasses pretty well. I can't give a 5th star yet as I'm not sure this will be a long term solution; the other factor that keeps it from a 5 rating is they probably would not fit all glasses and the clips although sturdy are a little thick and my nose is essentially resting on them so it's slightly less comfortable than it could be. I suppose they would be 5 and perfect with glasses that accommodate this feature. The clip-ons are well packaged and with protective cases and cloth bag to keep them safe.

So I've been doing a lot of research on this stuff and trying to figure out what would be the best option... - I knew that I needed something that would just clip over my prescription glasses, because I didn't want to have to put on my contacts to use a product. - A friend recommended blue light glasses for general sleep hygiene, which may in turn help with my ADHD symptoms. While I can't speak on that just yet, I will set a reminder to update this review in a week so that I can assess sleep quality/motivation stuff. If it improves sleep quality, I will update my review. -I also would like to add that this is NOT a paid review, which I've been super wary of when it comes to Amazon reviews. I am hesitant to trust rave/ "BUY THIS NOW!!!" type reviews. I decided to write a review so that people like me might have an easier decision process when it comes to newer products that might be considered snake oil. PROS: -Definitely block out blue light. I am wearing the amber lenses. While outside, I accidentally put regular garbage into my blue recycling bin instead of the black one. -Easy spring mechanism to clip on. I don't need a flip-up, and I read that they didn't add it to minimize weight. I don't know how much it would add to the weight, but the clip-ons are definitely light enough for my needs. -Noticeably ease eye strain. I didn't realize how much direct sunlight caused eyestrain, but it definitely made a difference outside (no squinting, less need for my eyes to adjust). -Satisfactory build quality. I haven't compared them other glasses, but these definitely do not feel like I was scammed/cheap-ed out on. -Comes with a microfiber(?) carrying case. CONS: -The glasses are very slightly asymmetrical in assembly on the spring mechanism, which doesn't affect the functionality of the glasses. If the company is not a huge manufacturer (which I've read they are not), I can forgive this. -I did notice there was a slight bit of glare reflected when faced away from the sun. -There's not much pizzazz with the box it comes in, nor any special offers/marketing material, but I guess it's a pretty utilitarian purchase. CONCLUSION: While these are higher in price than other products, I think the overall blue-blocking is very effective. The build quality is good, but not 100% perfect. The design is simple, and it covers my larger-frame high bridge lenses quite well-- probably about 1/4 of an inch is not covered on my lenses. I also like the retro look, but this is just personal preference. Won't make any recommendations for anyone else, but I'll say I don't regret the purchase. EDIT 7/29/21: So I've been using them for a little bit now, and I can say that I like them a lot. They seemed to have a pretty good effect on making me able to sleep faster -- I could be on my phone in bed and still feel the need to sleep. It's difficult to say on whether the overall quality of my sleep is better, but I think the ability to fall asleep easier is worth it to me. They are well made and worth the cost, IMO.

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

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 light They are best used at night before going to sleep, for people who are weak to blue light Because of how strong they are, I wouldn't necessarily recommend them for all-day use Pictures show with/without the lens

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.
