If you need the bifocals for gauge reading then it would be worth the cost. Your correction is fairly high so you could use it, but if you are simply looking for a mask for snorkeling or scuba diving then you should be ok with out the bifocal corrections. Also water magnifies by 25% so that may be an option as well for you. Please advise and I hope I have helped.
Happy Diving,

The only manufacturer that has an off the shelf bifocal is Seadive (also known as sea venture)

Otherwise that is a custom grind lens that can be found here

Hey There,
As far as off the shelf lenses go I am afraid that we cannot get them any longer. So, not no rather maybe, if you can find a supplier that still has the lenses.
Thanks,
Bill

Re: Prescriptive lens
Do we use the "Sphere" or "Cylinder" readings? Also if a -3.75 reading, do we choose -3.5 or -4.0?

Hello, not being an optometrist I would suggest that you fax us your prescription and we will have them looked over and the appropriate version chosen for you. Keep in mind that astigmatism does affect the vision as well water column magnification.

Hi There,
Lenses can be installed by you as long as you are careful about popping out the lens holders. What I mean is that it does entail some skill but as long a you carefully do it folks have had no problems. I will say that corrections -7 or thicker tend to be a bit of a challenge. If needed you can send the mask to us and we can do it for no extra charge.
Thanks,
Bill
