This is an add-on product (so inexpensive it doesn't make financial sense for Amazon to sell it by itself), but it's so good it's worth buying something else on Amazon in order to add this one on to your order. Really!
It is sold as a UV blocker; it claims to block 99.9% of UV-A,UV-B, and UV-C. I can't evaluate that. But I can verify that it is an EXTREMELY effective blocker of blue light. (Science note: UV, or ultraviolet, is right next to blue on the light spectrum, so something that blocks UV will probably also block a lot of blue.)
As a blue-blocker, these glasses are extremely effective. My cable box has blue LEDs. At night, normally I can see those LEDs with no trouble. Wearing these glasses, I can barely see that the cable box is on!!! My cable remote is the same; it has blue backlighting that I can't see at all when I have these glasses on. I have a blue terrycloth towel in the bathroom. During the day, with all the lights on, this blue towel looks *completely* gray when I'm wearing these glasses! White walls look yellow. Many other colors look almost normal (almost).
Why would anyone want glasses like these? Because they might help you sleep better. Scientists have shown that in your retina (the light-sensing surface inside your eyes) there are not only "rods" (to sense overall light) and "cones" (to sense red, green, and blue light for normal color vision), but also a fifth type of sensor designed to tell the daily-rhythm part of your brain when it's daytime. Those special sensors are at the upper corners of your visual field -- exactly where you would expect blue light from the sky to come in. Scientists believe (this is true! I teach biological psychology!) that your daily (circadian) rhythm is reset every day (this is normal) so that your body's chemical rhythms are in synch with the light and dark cycles of your environment.
And so? Well, your computer monitors and your smartphone screens all have lots of blue light. If you spend a lot of time looking at such screens after the sun sets, you may be "telling" your brain that it's still daylight out, and your chemical rhythms will tell you that it's not time to go to sleep yet.
I wear these glasses after dark so that, I hope, it will be easier for me to fall asleep and stay asleep, even if I spend time looking at the various screens in my life. I canNOT yet give a testimonial about whether this has worked well for me (it's only been 2 weeks), and of course I canNOT make any prediction about whether it will work for you. But I can DEFINITELY say that these glasses cut out all or almost all of the blue light that, scientists suspect, may interfere with people's circadian rhythms.
These glasses fit over your regular glasses, and they wrap around to filter light coming in from almost all angles (i.e., the top and side gaps that normal glasses have). I like these glasses better than the ones (sold by the same manufacturer) that do not wrap around (Uvex S1933X Skyper Safety Eyewear, Black Frame, SCT-Orange UV Extreme Anti-Fog Lens). Light at the upper corners of your peripheral vision is the light most likely to hit those special skylight-sensing retina cells, so these wraparound glasses should be better at blocking that light.
And at this price, who can resist? Others sell blue-blockers for Official BluBlocker Eagle Sunglasses times as much. This company just wants to sell an excellent product at a fair profit. Highly recommended!

SCT-Orange LensUvex proprietary Spectrum Control Technology (SCT) absorbs 99.8% of blue light wavelengths, as well as violet and green wavelengths. Clear “blue light blocking lenses” only filter about 5-10% of blue light, making them much less effective than our SCT-Orange Lens for viewing laptops, computers, tablets, smart phones, gaming consoles etc. |
Protects Your EyesProlonged exposure to blue light not only causes eye fatigue, it can also contribute to cataracts and other forms of macular degeneration. This is especially true in dark environments like when you're working at night. The Ultra-Spec 2000 SCT-Orange Lens helps inhibit these degenerative processes. |
Improved Contrast = Better FocusThe Ultra-Spec 2000 SCT-Orange Lens allows you to see more screen contrast with sharper details. This means your eyes don't have to work as hard, which reduces eye strain so you can work longer & more comfortably. |

Better SleepArtificial blue light can suppress melatonin production, disrupting your biological clock and impacting your sleep cycle. Uvex Ultra-Spec 2000 Blue Light Blocking Computer Glasses will allow your body to create the melatonin it needs, resulting in a better night’s sleep. |
Vented Side ShieldsIt's important to be comfortable while working, gaming or just surfing the internet. The Ultra-Spec 2000 model features vented side shields to ensure proper air flow and longwearing comfort. |
Extra Blue Light ProtectionArtificial blue light wavelengths can still reach your eyes peripherally, like when you turn your head slightly away from the laptop screen. Ultra-Spec 2000 glasses feature a wraparound uni-lens style with side shields to filter this blue light out. |

Yup. These absolutely work.
First, my thanks to E. Dean for her informative and personal posting about this product. I too have been having issues with my circadian rhythm and was advised by my physician to try out blue block amber glasses if I was to be using my computer at night. Good ole Amazon has these at an excellent price, and I wore them during my night time computer use. For me, there were no problems getting them to fit comfortably over my prescription glasses, nor did I think they're 'funny looking'. After about about two weeks, I did begin to notice an improvement in my sleep cycle. Absolutely wonderful. Now, if your skeptical about whether these actually function as advertised, please take a close look at the submitted photo's. They were taken with my Blackview BV9500 with no flash or night time enhancement. My keyboard is a TECKNET Gamming Keyboard that has settings for 7 colors. I chose the obvious one for this experiment, blue. The first photo taken in plain darkness. You'll see my keyboard, my 'borg' mouse, and my EASY MAC2 for my tablet, all three emitting a blue light. The second photo was taken with the UVEX ULTRASPECS held over the camera lens aperture. Same exact position. Wow! And the little 'orange' light you see on the right, that's the monitor 'on' BLUE LED! Pretty cool stuff there Maynard. So there you have it. Get them if your having the same issues like me. They're well worth the money.
