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.

What is your return or exchange policy for prescription lenses?

You have 30 days from delivery to return your mask. For full details, visit our returns policy on the Oceans Optics website.
