So how can I know whether or not a light produces some blue light? Alternatively, do you have any recommendations for blue-blocking goggles?

Probably a matter of "light temperature". Low temperatures of 2500-2700 K (aka "warm white") are reddish, while high temperatures around 3000 K (aka "daylight" [ETA: in advertising parlance]) are bluish. Go to a well-stocked hardware store and they may have a display demonstrating the differences.

  3000K is still considered very warm white. Daylight is 5700k. http://en.wikipedia.org/wiki/Color_temperature http://en.wikipedia.org/wiki/Color_temperature

All white lights produce "some" blue light. As the other comment mentioned, the white point/color temperature indicates how much. I'm a fan of lights with adjustable color temperature, such as the Philips Hue bulbs. I use ~5000K-6500K when working, then fade down to dimmer light at ~2500K in the evenings. I use a Kinect for this, rather than the Hue app.

I have Gunnars that I wear at home. The advantage is you're not limited in use when compared to flux. You can get them in prescription as well, however they're already fairly expensive.

  Gunnars do a great job at blocking UV and some kinds of glare, but they mostly don't block the light around 480nm, so they can't block all alerting light. You want glasses that look orange (not pale yellow), like the $7 Uvex ones.

Install dimmers! And use warm-dimming bulbs like incandescent/halogen (or some newer LEDs). The combination of lower brightness and a light that actually dims to 2000K will measurably wipe out the stimulus. Most other kinds of lighting will not.

If you just want to give it a try, the ones made by Uvex are pretty cheap and of good quality: http://www.amazon.com/Uvex-S1933X-Eyewear-SCT-Orange-Anti-Fog/dp/B000USRG90/ref=sr_1_2?ie=UTF8&qid=1406648843&sr=8-2&keywords=orange+goggles http://www.amazon.com/Uvex-S1933X-Eyewear-SCT-Orange-Anti-Fo...
