Can anyone identify this prescription mask?

[Sonic04GT]

I've only ever used the Tusa Liberator masks with EVO lenses from Divers Direct in South Florida. Not a fan of them, but they work. Well, I lost it today.

A buddy gave me this mask. The left eye is dead on, but the right eye is a little stronger than my prescription (4.5 vs. my 3.75). I'd like to swap the lens but can't find any identifying markings. I'm going to try it with the 4.5 tomorrow but I assume it's a good idea to get closer to my actual eyeglass prescription. Made in Taiwan on the strap.

Those lenses look like the ones for a Cressi mask, and many others, that are the same for L and R. Your old Tusa Liberatore lenses had to be either L or R.

I undersatnd you should undecorrect....the water refraction gives about a 0.25 to 0.5 diopter correction all by itself. So if you need -3.75, get a -3.5.

The mother lode for this stuff is AQUATIC OPTICS, Inc. Prescription, Corrective Lenses Price List.
At worst you could send them the mask and ask them for a lens for it.

Thanks a lot bud! The 3.5 Cressi showed a used one on Amazon for $10 shipped Prime so I’m going to give that a shot and see if it fits. Really nice that they’re interchangeable L/R. Otherwise I may consider that other site in the future for my Atomic Subframe that I haven’t been able to wear in forever.
I have a minor astigmatism so contacts really would be the best path if I ever get around to it. Thank you again.
