I took a selfie of myself with the AVP on and I noticed that the curvature of the AVP for the nose was not centered over my nose. It was skewed slightly and that got me to wondering how one can insure that it's centered if one can't see it when it's put on. Speaking of the nose, the AVP "nose curtain", the cloth that wraps around the nose should be replaced with something that hugs the nose more imo. Light can and does get it through in that area. At least for me it does.
