What is the difference between nearsighted and farsighted lenses?

Nearsighted lenses have a negative SPH value and correct distance vision. Farsighted lenses have a positive SPH value and correct close-up vision.

How do I find the sphere (SPH) value on my prescription?

The SPH value is usually in the first column of your prescription. A negative number indicates nearsightedness, while a positive number indicates farsightedness.

How Should I Adjust My Prescription for Clear Vision Underwater?

Select a lens strength 0.50 to 0.75 diopters weaker than your regular prescription to compensate for underwater magnification.

Can I choose a lens strength that isn’t listed in the dropdown?

If your exact strength isn’t available, pick a lens 0.50 to 0.75 diopters weaker than your prescription to maintain clear vision underwater.

Can I choose different lens strengths for each eye?

Yes, you can select different strengths for each eye if they are available in the dropdown.

How do I upload my prescription during checkout?

You don't need to upload it. Contact us via chat or email if you require specific strengths or assistance.

What happens if I accidentally choose the wrong lens strength?

Contact customer support immediately. We may be able to correct the order depending on its processing stage.

Are your lenses safe for both snorkeling and scuba diving?

Yes, all lenses are certified HD Tempered glass and safe for snorkeling and scuba diving up to 100ft.

How long does it take to receive lenses, and can I track my order?

Orders usually take 7-14 days to process. A tracking number will be provided via email upon shipment.

Let's embark on a journey to discover the ideal fit, setting the stage for unforgettable aquatic adventures.

Guide to Measuring Your Face for the Perfect Scuba/Snorkel Mask Fit:

Tools Needed:

Hard Ruler/Measuring tape
Mirror
Pen and paper

Steps:

Head Width:
- Start by measuring the width of your forehead from one temple to the other. Place the tape above your eyebrows and across the widest part of your forehead.
Cheekbone Width:
- Measure the width of your face across your cheekbones. Start from one cheekbone, just below the outer corner of your eye, and extend the tape to the other cheekbone.
Nose Bridge Height:
- Measure the distance from the bottom of your eye socket to the bottom of your nose. This will help determine the height of the nose bridge needed for a comfortable fit.
Nose Width:
- Measure the width of your nose by placing the tape across the top of your nose, just below your eyes. This measurement is crucial to ensure the mask's nose pocket fits properly.
Total Face Width:
- Add the forehead width, cheekbone width, and twice the nose width to get the total face width. This helps ensure the mask will cover your face adequately.
Distance Between Eyes:
- Measure the distance between your eyes. Start from the inner corner of one eye and extend the tape to the inner corner of the other eye.

Tips:

Use a mirror to ensure accurate placement of the measuring tape.
Measure in centimeters or inches, based on your preference, for consistency.
Take each measurement a few times to ensure accuracy.
