We made this for you! Read up on essential snorkeling skills, knoweldege and tips, before you take the plunge into the Ocean.
I really didn’t think I would be satisfied with this mask but after reading the reviews I figured I try it. I asked questions in my order and they were answered almost immediately. I received the mask and snorkel set very quickly. I’m thrilled I found this company and took a chance with them. You will be too.
I haven’t used them yet. I will next week while in Bermuda. I was skeptical at first but after receiving them and trying them on I was amazed. So worth the cost which is very reasonable. Can wait to use them.
The communication with the seller was excellent.
The glasses arrived within a week and a half.
Excellent glasses! The seller made one exactly as I told him to do.
And my daughter was really excited that she could see with them. She has it. The number is very high on the glasses and she can't see at all.
I highly, highly recommend it. The price is excellent and the service is outstanding!! !

What is the difference between nearsighted and farsighted lenses?
Nearsighted (Myopia) lenses: Negative SPH values (example: -2.50) to help you see clearly at distance.
Farsighted (Hyperopia) lenses: Positive SPH values (example: +2.50) to help with close-up vision.
How do I find the sphere (SPH) value on my prescription?
Look for the column labelled SPH or Sphere. It can also be labelled Power or PWR. A minus sign (-) is nearsighted. A plus sign (+) is farsighted.
How should I adjust my prescription for clear vision underwater?
Underwater adjustment: For most people, choosing a lens that is 0.50 diopters weaker (towards zero) than your normal SPH gives the best comfort and clarity underwater.
Why: Water creates natural magnification, and mask lenses sit further from your eyes than glasses. Reducing by 0.50 helps keep vision feeling natural and comfortable underwater.
Examples: If your SPH is -2.25, choose -2.00. If your SPH is -2.75, choose -2.50.
Our lenses are available in 0.50 increments, so choose the closest available option.
I have astigmatism (CYL). What should I choose?
Our lenses are sphere only, meaning they correct SPH but not CYL directly. You can still see a significant improvement. Use your SPH for each eye, then adjust based on your CYL value and sign.
Important: The + or − sign on your CYL matters. Check your prescription slip for the sign next to your CYL value.
Nearsighted (Minus −) lenses
CYL 0.00 to 0.75: Go 0.50 weaker than your SPH (closer to zero). The CYL sign has little impact at this level.
CYL 1.00 to 1.75 with minus CYL (−): Stay close to your SPH. You can go up to 0.50 stronger (further from zero) or up to 0.50 weaker (closer to zero).
CYL 1.00 to 1.75 with plus CYL (+): Stay close to your SPH. You can go up to 0.50 weaker (closer to zero) or stay at SPH.
CYL 2.00 to 3.00 with minus CYL (−): Stay exactly at your SPH. Only go 0.50 stronger if you specifically want sharper detail.
CYL 2.00 to 3.00 with plus CYL (+): Stay exactly at your SPH. Do not go weaker.
CYL 3.25+ with minus CYL (−): Move slightly toward stronger correction, rounded to the nearest 0.50 step.
CYL 3.25+ with plus CYL (+): Move slightly toward weaker correction, rounded to the nearest 0.50 step.
Special case: If your SPH is −0.50 or −0.75 and CYL is 2.50 or higher, start at −1.00.
Farsighted (Plus +) lenses
Our farsighted lenses come in whole steps only: +1.00, +2.00, +3.00, +4.00, +5.00.
CYL 0.00 to 0.75: Round to the nearest whole number toward zero.
CYL 1.00 to 1.75 with minus CYL (−): Round to nearest whole number, or one step stronger for sharper detail.
CYL 1.00 to 1.75 with plus CYL (+): Round down to the nearest whole number.
CYL 2.00 to 3.00: Stay at your SPH rounded to the nearest whole number.
CYL 3.25+ with minus CYL (−): Move toward stronger correction, round to nearest whole number.
CYL 3.25+ with plus CYL (+): Move toward weaker correction, round to nearest whole number.
Special case: If your SPH is +0.50 or +0.75, start at +1.00 regardless of CYL.
If you are unsure, upload your prescription and we will check your selection for you.
I can't find my lens strength in the dropdown. What should I do?
The dropdown shows all strengths available for that specific mask. If your exact number is not listed, choose the closest available option using the guidance above.
If you want us to confirm the best match, upload your prescription on the product page or email us at info@oceansoptics.com.
Can I choose different lens strengths for each eye?
Yes. You can select different strengths for left and right eye. You can mix and match any combination available in the dropdown menu.
How do I upload my prescription during checkout?
On the product page you can optionally upload your prescription so we can check your selection before we build it. You can also leave a note in the cart, or email us at info@oceansoptics.com.
How do I stop my mask from fogging?
A simple method is the toothpaste trick. Rub a small amount of toothpaste on the inside of each lens using circular motions for a few minutes, then rinse thoroughly. Do this before your first use and repeat if needed.
Before each session, you can also use a tiny amount of baby shampoo or dish soap mixed with water. Rub a thin film on the inside of the lens, then lightly rinse so a fine layer remains.
Do you have a guide to help me use my mask properly?
What happens if I accidentally choose the wrong lens strength?
Message us as soon as possible. If the order has not entered the build or shipping stage yet, we can usually update the lens selection.
Are your lenses safe for both snorkeling and scuba diving?
Yes. Our lenses are HD tempered glass and are suitable for snorkeling and scuba diving up to 100 ft (30 m).
How long does delivery take, and can I track my order?
Most orders arrive in 5 to 10 days, but we recommend allowing up to 14 days to be safe. You will receive a tracking number by email once your order ships.
What is your return or exchange policy for prescription masks?
Your satisfaction, guaranteed.
You have 30 days from delivery to request a return, as long as the item is unworn, unused, with tags, and in original packaging. For full details, visit our Return Policy.
