I use a WIA blue auto helmet. I have spent many many hours under it and so far absolutely no ill effects.
The helmet has a really nice feel and curve to it that seems to eliminate uv reflection. Also the acctuall head gear is very comfortable and light... From memory I paid about 250$ for it from my LWS.

I got howled down for this one on another forum because no one wanted to believe me, but once I was using an auto helmet that switched in 1/4000th of a second. At the end of the day, gritty eyes. I then got one that switched 1/20,000th of a second and didn't have a problem.
I personally believe that switching time is important . As others have said, you only have two eyes, so buy the best you can because the cheap ones don't switch as fast (and at least with the name brand helmets there is a reputation to stand behind the product).

Again,
I must reinforce the message that you are not completely safe (while welding) unless you are wearing safety glasses under your welding helmet.
While your helmet is up you are vulnerable to an eye injury via the following modes.
- * Hot Flux(electrodes or Fcaw) or silicate flicked off the bead (from GMAW) entering your eyes
* Spatter or hot metal in the eye from an accidental arc strike.
* If working near another welding operator, then UV from that source.
Also I am sure there are those who are more prone to eye irritation from welding than others all things being equal.
The grittiness suffered in the eyes is a symptom UV damage. However the switch time allow dazzling effect as felt from an oncoming high beams while driving at night may well result in strained eye function from excess light, but this is not UV. My ophthalmologist confirms that UV damage can only
occur to the naked eye.
Just to make the point clear, Ok!
regards
Grahame
