I mean arc weld

1. You don't encouter UV rays unless you are welding without eye protection. Don't do this.
2. This is urban legend:

Paper>does anybody weld wih contact lens?

While the concept of UV rays "welding" contact lenses to your eyes has been properly relegated to Urban Myth status......

....most people who wear contacts have been cautioned by their opthamologists about wearing contacts in atmospheres that are laden with irritants such as dust, vapors and smoke.

Such irritants can be trapped between the lens and eye, creating conditions ranging from mild irritation to fairly substantial pain.....but, not likely threatening eyesight.

Arc welding creates a lot of smoke as the rod coating burns. In a well-ventilated shop, it should cause no problem, but in a confined, poorly ventilated area, there is the potential of eye irritation.

I think this particular Urban Myth is a good example of someone taking a logical precaution to its illogical extreme......

I prefer to weld with contacts. I wear bifocals otherwise, and welding with a combination of contacts and cheaters gives me the clearest picture of what I am doing. Welding with bifocals is difficult.

YMMV

You know what I find perplexing about that ...............

A $400 set of glass bifocals will catch and hold molten dingleberries in a crater that looks like it is hitting candle wax. Those $3 plastic cheapies throw off those molten dingleberries. I thought glass was denser than plastic, therefore harder for molten things to stick to. But it is just the other way around. It won't faze a cheapo pair of glasses, but will mess up a good pair every time.

Go figger.

Seems like some #10 contact lenses would be to thick for my eyes, and the sun burn on your face would suck. :)

done it for years.
