Having studied art since i was 8 and having gone to art school, I've learned how to avoid dremel and hot glue accidents.
For eye protection, I've gone through a bunch of different options over the years, and this goes for not just building but gaming as well: I started with ordinary sun glasses and that didn't work; then i tried all sorts of different shop goggles and they were quite safe but always left marks in my face and made me sweat. also they fogged up. I tried shooting glasses too but the lens distortion gave me a headache.
Finally I said F-this and got a pair of ESS turbofan goggles recommended to me by some folks on an airsoft forum:http://www.amazon.com/Profile-TurboFan-Military-Tactical-2-Speed/dp/B002YUW19M/ref=sr_1_2?ie=UTF8&qid=1349647157&sr=8-2&keywords=ess+turbofan
They are over $150 but they are literally shrapnel-proof. The fan keeps them from fogging. Sweat does build up where the foam gasket touches your face but you'll never sweat under the goggles. I've used mine in the shop and in nerf combat and I have to say they are excellent. Also the sleeve that you see on the strap can be stretched over the lenses as a dust cover so you can keep them from getting scratched when you're not using them. It also doubles as a lens cloth.
