Goggle lens thickness

Postby Peaches » Tue Mar 10, 2009 11:05 pm

I was looking at some goggles on ebay, and they give the thickness of the PC lenses, anyone know what is the best thickness, and what is the worst thickness for safety???

We just use the ANSI standard. The specific thickness isn't important so long as they are ANSI spec.

The problem is that while looking I couldn't find any ANSI ratings on any of the goggles that I looked at.

ANSI Z87.1-2003
Lens thickness requirements for goggle lenses, faceshield windows and welding filters are unchanged. Basic impact lenses in these product categories must be at least 3.0 mm thick.

So 3mm of polycarbonate should do the trick.
