FreeMascot OD 4+ 190nm-540nm Wavelength Laser Safety Glasses for Typical 405nm, 450nm, 520nm, 532nm Laser Light for Hair Removal Laser Treatment Eye Protection Goggles (Red)

These block UV A, B and C wavelengths which I work with. Needed some general eye protection in case any strong light sources reflect my way. Will fit over my prescription eye glasses.

😎 i love these glasses! They are only $10 and they are the most effective blue light filtering glasses. I wear them every night after 8pm to help me get to sleep. Worse/ less effective version of these (but are advertised/branded) sell for $100+ to people in the SF bay area with similar sleep concerns

Though everyone makes fun of me, joke's on them! I use these to enhance my bedtime routine, as the rest of the house doesn't seem to mind every big light on after 11pm. 😆 They've made every light into "candlelight", and act as a major bonus when using at-home laser hair removal. They're sturdy, cancel out light from all angles, and don't fall off my head after wearing for too long. Sometimes I fall asleep with them on and I don't experience any discomfort, which is nice. Highly recommend! Great price, many uses!

Blue blocking is really good on these but it doesn't fully cover full peripheral vision like uvex. It gets uncomfortable on my nose and it clamps on my head pretty badly. the dimensions of the product are listed which is a plus. It's not bad for the $ and I think the red is far superior to the orange ones.

Cool. These will be able to block the wind when I ride my scooter and also protect me from the unhealthy fluorescent lights that places of business have installed. Docked a star because the glasses came out of the package with light scratches on the bands. Were these used by another customer or just handled roughly by the merchant? I sprayed them with rubbing alcohol.

little tiny holder for the arm broke. Not enough support and broke clean off.

So my body's schedule is perfectly fine when I am backpacking and outside 24 hours a day in beautiful summer weather. However, if it's an overcast day, my delay is 2-3 hours, for a 26-27 hour cycle. If I'm sleeping in a room without a real direct-light window, my delay is 5 hours, for a 29 hour cycle. I have had narcolepsy and a severely delayed circadian rhythm my entire life if my light exposure is not completely synced to the equivalent of full outdoor sun. People without this problem will make suggestions like "just go for a 15 minute walk outside every morning". No, I literally need continuous full outdoor sun THE ENTIRE DAY in order to not fall asleep midday. As you can imagine, this is very bad for work. I thought my night light exposure was fine because I have already switched over all my bedroom lights to dim orange/amber lights and have blue filters on my computer and phone, but it turns out that these red goggles do even better. They filter ambient street light, fridge lights, not-so-orange common space lights, and other random lights I might accidentally see walking around the house in the evening that I don't think about. These red goggles solved half of my problem. When I start wearing them 2+ hours before my target bedtime, I actually feel sleepy by my target bedtime, even if it's before midnight. Game changer and much better filtering and wraparound than standard blue-blocker glasses for only $10! Pure blue lights are completely invisible through these glasses, it looks like nothing is on. For the other half of the problem -- simulating full sunlight on days when it's either overcast, or I need to work indoors -- I read OptimizeYourBiology sun lamp reviews and ended up buying the Luminette 3 (~$200) and Alaska Northern Lights Mini Pad (~$200). I balked at the prices at first, but they have proven to be a very good deal considering they are giving me back several hours a day every day that I would usually spend struggling with my severe sleep disorder. I can finally cosplay as a normal person, at least where being awake is concerned. FYI, you'll get much better customer service if you buy directly through their websites rather than through Amazon.

These safety glasses are excellent, they provide great wrap-around coverage which is something I find lacking in many inexpensive pairs. They're quite large, they fit my enormous head comfortably even over my prescription glasses which I was really not expecting - they're so large they can even fit over some of my old laser safety glasses. I wish I could verify their claims about optical density, but I can say is these do thoroughly block the scatter from my 455nm blue laser engraver, just about any source of clean blue light disappears with these on. Very happy with these, a welcome upgrade over others I've tried in this price range.

These glasses really block a lot of blue light and a small portion of the rest of the spectrum. Decent build quality and very good coverage of the face. These make excellent night time blue blockers and are priced reasonably.

Use these for painting portraits. Why.. Looking at a reference shows only one colour red and it makes distinguish between colour values much easier.. Fits nicely over my glasses. I look like a fool from the future.. But I need function not style. Perfect for oil or acrylic painters who need some help with values

One minor problem - there's a small gap between the bottom of the glasses and my face. Still good protection, just not excellent. I would give 4.5 stars but I don't see a way to do that so 4 stars it is.

Nice and perfect product, I recommend it

Glasses are a good fit and work as intended. Could be less uncomfortable but it is not too bad. Comfort may be an issue for long term use. Came with a case and cloth for cleaning. Both items reek of a strong chemical smell. After washing and airing the cloth the smell has lessened but is still there. The smell on the case is still as strong as the day the package arrived. I will have to throw out the case and cloth, but the glasses are fine.
