Mask Description
Mask Description
The RX Titan Prescription Mask for Nearsighted Divers and Snorkelers is built for underwater adventurers who need clear vision and a roomier, more comfortable mask fit.
Designed with corrective tempered glass lenses for nearsighted vision, the RX Titan helps you see clearly underwater without contact lenses or blurry views.
Its larger frame, soft silicone skirt, and wider nose pocket make it ideal for medium to large face shapes, especially for customers who find standard masks too narrow or tight around the nose.
The wide viewing field keeps more of the underwater world in sight, while the easy-adjust buckles and comfortable nose pocket make it suitable for snorkeling, freediving, and scuba diving.

What people are saying about Our Rx Masks
-
⭐⭐⭐⭐⭐ Joe, Arizona"Fantastic! The last time I went snorkeling (more than 10 years ago) I wore contacts. At age 65, glasses only. I thought I was done snorkeling, until I found these! They worked perfectly! | could see the fish. And at around 80 bucks for the mask and a breather tube, it's a bargain.
They charge like $25 to rent them at the beaches when you go on a cruise (and it is gross using something that was in someone else's mouth!) I highly recommend these if you are near-sighted and want to snorkel."

⭐⭐⭐⭐⭐ Allison R, FloridaPrescription goggles
We ordered a pair of prescription goggles for our trip to Hawaii and couldn't be more please with our purchase.
Shipping was quick and they worked great!

⭐⭐⭐⭐⭐ Sage, Utah"I got the obsidian, my sister got the lumix, we also decided on matching snorkels, and they looked so cute together. We went snorkeling in mexico, and this time was so much less scary since not everything was blurry.
There were also some really cool tips in the snorkeling guide, we found the part about buddy safety and communication especially useful."

Your Mask Helps Build and Grow a Coral Reef!
When you buy from Oceans Optics, you are not just getting an excellent mask, you are helping us build a real living Coral Reef.
A portion of every sale goes towards our artificial reef project in Koh Tao, Thailand. We worked with Global Reef and the Thai Department of Marine & Coastal Resources to sink a custom steel structure shaped like a prescription scuba mask. Onto this frame we attached living coral fragments that grow over time, attracting fish and turning the structure into a living reef and safe haven for marine life.
So each time you wear your mask, be proud that you are also contributing to saving ocean we all love.
