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?

Product Description

The XViz Aluminum Finger Reel is the ultimate tool for underwater navigation, SMB deployment, and search and recovery missions. Made from T6061 aviation-grade aluminum alloy, this 30m spool is lightweight yet incredibly robust, designed to withstand the rigors of deep dives and technical applications.

The sturdy polyester fiber braid keeps your line secure, making it ideal for wreck, cave diving, and other demanding environments. A top swivel attachment prevents tangling, letting you focus on your dive without hassle.
