Steam free: Gail Shuttleworth’s old glasses rapidly steamed up, yet it’s all clear with the new focal point coating
Normally, at the point when warm air hits the colder surface of a match of glasses, water vapor gathers on the focal points as tiny droplets.
But the covering avoids the beads from forming, meaning the dense waters frames a thin layer over the focal point instead â€“ what’s more, that layer is adequately undetectable to the glasses wearer.
