Comments about Mares Mares Corrective Lenses Positive Bi-Focal Diopters for X-Vision & Liquidskin Masks:
I love the fit of the mask but, The Bi-Focal lenses have a big flaw. The edge of the bi-focal leaves about 1/4 inch gap between the bi-focal and the nose cover. Thus my eyes lined up exactly with the edge of the bi-focal making it even harder to see the gauge. If they could take the bi-focal all the way to the edge this would be the perfect solution for those of us over 40.
