How does this lenses work? Does it fit on top of the mask lenses? If so, how is it secured? Is only the bottom enhanced to correct for far-sightedness, or is it the entire lenses?
Thanks Bob. As a full lens replacement, does it come with instructions on how to do this? Sounds like a good solution for me!
