Manual Ruler Guide

Prefer to measure yourself with a ruler or tape? Follow our step-by-step guide below.

  • ✓ No camera needed
  • ✓ Works anywhere
  • ✓ Fine-tune with sliders
Measure eye width

A Eye Width

Measure from the outer corner of one eye to the outer corner of the other in a straight line. Use a ruler, soft tape, or even a phone charger cable (then measure the cable against a ruler). Keep it flat against your face.

in ✓
Measure mask height

B Mask Height

Measure from just above your eyebrow line straight down to just below your nose. Use a ruler, soft tape, or phone charger cable. This is the vertical space where the mask and silicone skirt will sit.

in ✓
Measure head circumference

C Head Circumference

Wrap a soft tape, string, or phone charger cable around your head above your ears and eyebrows, like measuring for a hat. Then measure the length against a ruler. This tells us how the strap and silicone skirt will seal around your face.

in ✓
Nose pocket sizing

D Nose Size

Some masks have a narrower nose pocket. Selecting your nose size helps us rule out masks that may dig in or feel uncomfortable. If you're unsure, Medium is a safe choice.

✓

Your Measurements

Fine-tune with the sliders, or go back to re-enter.

Why head size matters: If your face says Small but your head is Medium-Large, the smaller mask strap may not seal properly. We will show both options with notes.

I saw the fish!!!

I love, love, love these goggles! I can finally see all the fish when I go snorkeling. The goggles were made to my exact prescription. I could see all things underwater perfectly. The goggles didn’t leak or fog. Best snorkel gear ever!

I can Sea! I am so excited to use these! I can see through them and feel excited more than ever now to go snorkeling! Thank you for giving me my sight under water :)

Rx Obsidian Nearsighted Prescription Snorkel & Scuba Dive Mask

I cannot reccomend this enough for people who need perscription lenses. Makes snorkleing/ diving much more enjoyable and I prefer the lens quality compared to a non RX regular mask. Its very clear and fits well! No complaints or issues. If youre hesitant about what perscription to get, include your RX and someone will reach out to you with reccomendations (i went with their rec). Pretty fast shipping too.

All around a great mask!!!

Excellent mask! I used this for a trip to Roatán. I've never worn a prescription mask before so I didn't know what to expect. On our dive down to 55ft it sealed great, no leaks!! I followed the instructions about how to fog-proof the mask and it worked, no fogging! Best of all, I could actually see!! Great customer service as well. All in all a fantastic experience.

I can't believe these weren't expensive

I can't believe I let some years go by thinking that prescription masks must be super expensive. These aren't. I haven't used them yet, but just wearing them in the house and looking at objects that I know would be a little fuzzy at a distance, were incredibly sharp. Mask made of silicon is a plus.

This worked beautifully

This was my first time snorkeling. I never went before because I can't see well without my glasses. Honestly, I was nervous about it. But, I didn't need to be. Everything worked really well. I could see. I could breathe. In the end, I had a blast.
Even the boat captain commented that it was a really nice set.

Allowed my daughter to snorkel and see everything!

My daughter has bad eyesight, -7.5 prescription. She doesnt do well with contacts so wears glasses all the time. Without them she cannot see 3 feet in front of herself. These were so easy to order, arrived quickly and allowed her to really enjoy our snorkel trip to St. Croix. They worked great, no issues with using them. Thank you so much for this!!

I ordered this mask for my trip to Thailand, and it came I pretty fast! I ordered the white mask/fin/snorkle set and backpack to carry it all in, I felt so cute and everything worked so much better than the gear I would rent in the past. Thanks Ocean Optics! I love you guys and your mission.
