Not sure how you *compared* masks on the net??
While your logic makes sense in how we *see* what you fail to then grasp is that light coming into the side of a clear mask is not what the eyes are focusing on, nor can one SEE well (or really at all) through a clear skirt. It's NOT all that clear.
Light comming into the side of the clear skirt will either be ignored, or will result in a distraction taking the attention off the objects that CAN be seen within the visual area that a given mask allows.
Try this, look through a paper towell tube. Now punch a bunch of holes through the paper towell tube, and have someone shine high power flashlights into the holes on the side. As there is more light entering the tube from the sides, based on your logic everything should be MUCH clearer yes? No, the reality is that the light coming into the tube that is outside the focus at the end is REALLY distracting.
