Why are UV protective eyeware Orange? Many industrial processes use uv as a curing agent.  When one uses such a process, one must protect one's eyes from the radiation.  Most uv protective gear I have seen is tinted orange?
Does this orange color come from the actual uv blocking chemicals, or is that color added for some user related reason (like being confident you picked up the right glasses)
 A: For typical laser goggles the color of lens is the color of light that is transmitted through the lens.  Thus if the lens is red, it will not protect you from laser beams that are in the red portion of the spectrum.
The color you are looking for will be, in some sense, the complementary color; since red-orange-pink are far from blue-violet-ultraviolet, these are the lens colors you would expect to work for UV light.
I have often worked with high power, class 3B and class 4, UV lasers, from 405 nm, which is UVA, down to 264 nm, which is beyond the UVB. The typical goggles which cover these ranges are orange to pink.  
Your hypothesis is correct: the color comes from an absorptive dye which is incorporated into the plastic or glass.
It is also possible to apply multi-layer optical coatings to the lenses of spectacles which will preferentially reflect in the UV; this is a more expensive approach (hence dyes), and relies on destructive interference for the transmitted waves. The goal is to make make it transparent in the visible spectrum.
