What is the difference between nearsighted and farsighted lenses?
Nearsighted (Myopia) Lenses: These lenses have a negative sphere (SPH) value and correct distance vision. Farsighted (Hyperopia) Lenses: These 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, marked as "SPH" or "Sphere." A negative number indicates nearsightedness, while a positive number indicates farsightedness.
How Should I Adjust My Prescription for Clear Vision Underwater?
Prescription Adjustment for Underwater Clarity: To achieve clear and accurate vision underwater, we recommend selecting a lens strength that is 0.50 to 0.75 diopters weaker than your regular prescription. This adjustment helps to compensate for the magnification effect that occurs underwater, reducing the risk of distortion.
Example: Your Regular Prescription: Right Eye (OD): Sphere = -2.75; Left Eye (OS): Sphere = -3.50. Recommended Lens Strength: Right Eye (OD): Sphere = -2.00; Left Eye (OS): Sphere = -3.00.
Can I choose a lens strength that isn’t listed in the dropdown?
The lenses listed are the only ones available for the specific mask in the listing. If your exact strength isn’t available, select a lens that stays within the recommended adjustment range of 0.50 to 0.75 diopters weaker than your regular prescription. This ensures you maintain clear and accurate vision underwater within a safe and effective range.
Can I choose different lens strengths for each eye?
Yes, you can select different lens strengths for each eye based on your individual prescription. We offer a range of lens strengths, and you can mix and match any combination if available in our dropdown menu.
How do I upload my prescription during checkout?
You don’t need to upload your prescription. If you require specific lens strengths or have questions about your order, please send us a message through the online chat or email us at info@oceansoptics.com. We’re happy to help ensure you get the correct lenses for your needs.
What happens if I accidentally choose the wrong lens strength?
Contact customer support immediately if you choose the wrong strength. We may be able to correct the order, depending on the processing stage.
Are your lenses safe for both snorkeling and scuba diving?
Yes, all our lenses are certified HD Tempered glass, safe for both snorkeling and scuba diving up to 100ft.
How long does it take to receive lenses, and can I track my order?
Orders typically take 7-14 days to process. You will receive a tracking number via email once shipped.
