Clip-on Blue Light Blocking Eyewear

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.

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 had previously used another brand of bluelight glasses, but accidentally broke BOTH my older pairs... Found these ones and though they are pricier than other options I've tried, I decided to give them a shot. Maybe pricier means better quality? In this case, it absolutely does!!I'm on screens 8 hours a day for my job. Then I'm on screens for my favorite hobby (music production). Then I'm on screens for my second favorite hobby (video games). Needless to say, I'm on screens A LOT!These glasses have done everything right for me:- Colors are retained well when you have these on - they have hardly impacted my experience of any of my favorite video games.- These are not cheaply built. They are very sturdy. The framing is strong and the clip is a perfect tension such that I have no fear of damaging my glasses, but they will stay affixed properly.- Sleep quality improvements. This one was the most noticeable for me. My eyes are much less strained with these on during the day, and I find it easier to fall asleep after a full day of wearing them. The previous glasses I had did not yield such effects.If you've got the budget for these, do it. Totally worth it.

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.

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.
