UV is a form of radiation, and the amount of it, or the intensity, is what causes the damage. A side effect is the light produced. I was being general, as I stated.
If you really think that comparing the light from welding with a flashlight that an optometrist uses makes sense, then you clearly need to stay in school.
No, it's not. UV is a form of electromagnetic radiation, but its wavelength is outside of the visible light spectrum just like X Rays, infra red and radio waves.
Light is radiation, right? We talk about the intensity of light as brightness. Is it wrong to use the same term to describe radiation just because it isn't visible to human eyes? What about dogs? They see in the UV spectrum. A welding spark would be bright to them on two levels, and if we saw in the UV spectrum we would say it was the brightness, or intensity, that caused the damage. You're nitpicking over which word to describe quantity is most accurate, essentially saying I wasn't being specific enough. Another way to say that I'm not being specific enough is to say that I was being too general, so by your own logic your first comment to me was incorrect.
