Student question: if looking at light from lasers and acetylene torches both
hurt the eyes, how does that work? Aren't they different wavelengths?

Not simple, I can see that! But lasers, some lasers, I read, focus infrared
light, but acetylene torches: don't they give off ulraviolet???? What
happens, esp. considering laser eye surgery?

Thanks, Karen W.
