We ordered the prescription masks from a guy in Texas- he had an add at the back of porthole Magazine. He is an optometrist that loves to dive & saw a niche market.
Would love suggestions on the DRY snorkels!?! the clamp thingees on are old ones have broken and I don't remember where we ordered them- it has been 11 years!
And if you're wondering- yes our prescriptions have changed, but I'm not ordering a bifocal mask
