I am looking for corrective lens and a new scuba mask. How do I know if bifocal lens are worth the extra cost? Prescription: R: -4.00 -0.25 035 +2.25 (add) L: -3.00 -0.50 098 +2.25 (add) PO= 66

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,

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.

I was going to buy these lenses for my tusa powerview 2 mask ...are they fairly easy to install on my own or will i need to take it to a dive shop? thanks.
Answer by Bill

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

Can I get a replacement part for the Saturn IST Mask The art that secures the lens in place has broken. Thanks Michael OLdstone
Answer by chris
on 2/21/2017
Hi, Thanks for your question. There is no replacement part for your mask. I asked our Optometrist if the lenses could be moved to a new mask and he said that is not possible and that you would have to start over. Depending on when purchased your mask, it may still be under manufacturer warranty. If you have any other questions, please let us know. Thanks Divemaster Chris
