## Description

desertcart.com: 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) : Industrial & Scientific

Review: Large, Comfortable, Effective - 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.
Review: helped fix my extremely severe DSPD. I can finally get sleepy at night and be awake during the day - 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 desertcart.
