Steve: You might want to consider Aqua Dive Optx flexible mask magnifiers.....you can find them shown as an accessory on the masks described in Leisure Pro site. The way I found them was looking at the Atomic Frameless mask on Leisure pro site and then clicking on accessories....they come in 1, 1.25, 1.5, 1.75, 2, etc,ect +.........I haven't used them yet so I can't give you a report but I have just ordered them and look forward to trying them out to see how they work.....it's definitely an alternative to the $150-200 for prescription lenses.
