Choosing the right rx lenses for scuba diving

Understanding eyeglass prescriptions can be confusing, and ordering the right lenses for your needs can be daunting. To help, we’ve explained the differences between our lens offerings and why they may or may not be suitable for your underwater activities.

Plano Lenses

In the optical industry, “Plano” means “no prescription.” If you don’t wear glasses or contacts, this is the option for you. Plano lenses are clear, tempered glass unless you select a lens filter such as Color Correcting or MaxVision, which will be tinted CR39 or plastic material.

Single Vision Lenses

Single vision lenses correct eyesight at a single distance, either for nearsightedness (Myopia) or farsightedness (Hyperopia). If your prescription includes sphere, cylinder, and/or axis power, this is the best option for you. If your prescription includes an ADD power, consider bifocal lenses instead.

Bifocal Lenses

Bifocal lenses are for those who need correction at a single distance and also need help reading up close. The ADD power in your prescription determines this. Bifocals are ideal for presbyopic scuba divers, underwater photographers, or anyone needing to read a dive computer or gauges underwater. If you’re using your mask only for snorkeling, single vision lenses can accommodate your distance-only prescription.

Gauge Reader Lenses

Gauge Reader lenses are similar to over-the-counter readers. They combine plano and bifocal features, with no prescription in the upper portion and a bifocal with a +2.00 ADD for reading up close underwater. This option is perfect for those without a prescription but who still need help reading up close.

We hope this guide helps you choose the right lenses. As always, we’re happy to assist you with your order.
