I also bought the UVEX and they are unusable for me. I wear glasses, and there just isn't any room for accommodation, so still searching on that front.
I've been making it a habit for the last couple of weeks to turn off all the lights at 10:00 and light my lantern and candles and read for an hour before bed, I feel like this is helping.
I bought a pair of computer glasses from Taime([url=http://www.halovis.com]Computer Eyewear & Gaming Glasses - Taime Optics[/url]), they claim that this eyewear can filter 97% of blue light as below. It's a little pricy but feel much better when staring in front of the computer.
Not sure if these fit the bill for what you want, but I've been a long time, very satisfied wearer of Serengeti Drivers. They are designed primarily for highway use, but have a blue-blocking effect, and lenses that shift from light to dark depending on how bright it is. Not cheap.
