Clip-on Blue Blocking Amber Lenses for Sleep - BioRhythm Safe(TM) - Nighttime Eyewear - Special Orange Tinted Lenses Help You Sleep and Relax Your Eyes (Regular, Nighttime)

A fantastic quality product which is worth its value. I like the spring in the clip that comfortably clings to the spectacles and the vision is bright and clear. Good quality eyewear is important if you want to have your eyes working. Especially when you wear spectacles, and work for hours or watch TV, just clip this on.

Muy buena calidad del producto y lo más importante, el cuidado de la vista. Se siente la mejora del sueño y el menor cansancio de la vista para finalizar el día. Los utilizo las últimas 3 horas del día y me ha funcionado muy bien

I bought these because I look at screens for 3 or 4 hrs. a day, plus watch TV in the evening. Prior to purchasing these, I used a pair of clip-on lenses from another company for a couple of years and they did make my eyes feel a bit better when looking at screens but did nothing for my interrupted sleep at night. These lenses make a difference in my sleep! They are a deeper amber than the last pair. I believe they do actually block the correct wavelengths that can improve sleep. All eye strain is gone as well. I would buy these again!

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.

They work great and great customer service

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.
