At a guess...less distortion for looking ahead, but a greater loss of peripheral vision. Probably less discomfort for long-term wear. Heavier.

I think we might be trying to solve too many problems at once here. The eye protection you want for, say, digging supplies out of a destroyed house (where you worry about debris and dust, but you're going to be wearing it for hours at a time while doing heavy labor) might not intersect with the eye protection you'd want when dealing with a bio or chemical hazard.
