It has adjustable temple length and lens inclination. The lens is a large but snug-fitting wraparound shape...seems designed to fit adult men best. You can't wear prescription glasses underneath. It fits me perfectly with no light trespass around the edges. But I don't like the padded earpiece design - they put pressure on my head...but that's just me. I prefer Uvex's regular (non-padded) earpieces. Everyone has a different face & head shape, so your experience may differ with regard to fit and comfort.
The SCT Orange lens tint blocks virtually all ultraviolet, violet, and blue light while allowing most of the longer wavelengths (from green to red) to pass through (see the spectral chart). This gives it a deep orange color. Unlike many other orange lenses, this is a true 'blue-blocking' lens tint.
These are specialty safety/work glasses and might be a bit too bright for most people to use outdoors as sunglasses. The upside is that they aren't too dark to use indoors. But I do often use mine for working outdoors, and indoors in the hour or two before going to bed - to block out blue light from all light sources...especially TVs, and computer/tablet/smartphone displays.
Since they so effectively block the blue and violet part of the spectrum, color discernment is poor; these aren't meant for driving or anywhere you need color perception, seeing traffic lights, etc. If you need good color perception, Uvex has a brownish-colored lens tint called Espresso, which is excellent as a general purpose sunglass tint. It is darker, and does a good (but not as complete) job at attenuating blue light.Read more ›
I know these glasses work when I can't see the annoying blue LEDs on my laptop. (They look a dark green.) Also, my Philips GoLite has been reduced to a dull shine that I can stare directly into with impunity ... not that I'm crazy enough to use the GoLite at night.
As for regulating sleep rhythms:
I ordered the glasses along with some slow-release melatonin. I never used the melatonin. After 4 hours of "glass time," I was ready to sleep, and I slept on time -- by 5AM. 3 weeks later, I was sleeping at 2AM. Now I can dream the wildest dreams -- bedtime by midnight. Meeting friends in the afternoon. A regular 9-5 job.
I've tried a lot of different things over the years. The GoLite helped with daytime sleepiness, but it didn't seem to help with the night-time awake-ness. I tried exercise, which only works when I'm not so dead tired that I can actually do it. Finally, I did over-the-counter sleep pills.
When I think about it, extreme night owls like me should have been selected out of the gene pool long, long ago. The problem must be elsewhere. Not with genetics or lack of sunshine, but with LCD screens, fluorescent lights, 24-hour television programming, etc.
A quick search on Google Scholar reveals that DSPS sufferers are /more sensitive/ to artificial evening light than normal people.
All it takes is having extra axons connecting the (newly-discovered) receptors in the eye to the suprachiasmic nucleus of the hypothalamus. That's the same place that signals the pineal gland to spit out melatonin, the sleep hormone. Coincidence?

- Blue light is great for being awake - that's why you wake up with a blue sky (read about melanopsin and melatonin on Wikipedia)
- Blue light is not good for sleep; in the 470 nanometers range, that suppresses melatonin (a key hormone for sleeping well)
- Humans (and other animals) evolved to sleep in the dark - or, at the darkest, full Moonlight (just 0.1-0.3 lux of light)
- Longer wavelengths of light were the only source of light at night for most of human history (fire / candles)
- Tablets / phones / screens / LED's and many CFL bulbs have strong blue wavelengths that are messing with our circadian rhythms and suppressing melatonin, because they have wavelengths shorter than 530nm - 540nm
So what to do in our modern world? Wear these glasses before bed. Natural melatonin production would have occurred with our ancestors starting with the onset of sunset. Wavelengths of light from the setting sun would have shifted to red, and fire or candles were usually the only form of light available. Those are both relatively dim, and in longer wavelengths.
Today, our "connected" world has a LOT of blue light. It's messing with our sleep patterns, because our bodies evolved to only see red/orange/yellow light at night, NOT blue light/shorter wavelenghts.
THESE GLASSES BLOCK THOSE MELATONIN SUPPRESSING WAVELENGTHS.
Put them on a couple hours before bed. For me, I start getting drowsy about 90 minutes after wearing them.Read more ›
