Last week at DEMA I was at the booth of the company from San Diego that fits prescriptions into masks.
Presently I use a Seavision bifocal mask which comes prescription from the manufacturer. I really like the Atomic Frameless, but I'm not certain that adding a prescription will be a good idea, because of course they increase the thickness of the lenses by gluing on the bifocals. I guess this could be beneficial as it would decrease the mask volume even further; though I'm not sure if it would change the clarity / visibility of the mask.
Anyone have any input?
