I actually made my own safety glasses out of some recycled 3d glasses from a movie theater and the amber safety lenses that are at the business end of our U.V. light source wands at my work. I tested them by shining my ~2W 445nm handheld through the amber lens which didn't allow any of the light to pass through. it's kinda crazy how it completely makes the beam invisible and how dim the dot is on the wall and the best part is that these were completely free for me to make!
