Quick answer: These are full prescription lenses for Promate SeaViewer series masks, including the Sea Slender and Pro Slender. They're sold one lens at a time.

Why it matters

A corrective lens lets you see the reef and read your gauges clearly without wearing glasses under a mask, which you can't do.

What you get

• Single full prescription lens for Promate SeaViewer series masks

Options

• Lens: Nearsighted -1.0 to -10.0 in 0.5 steps; farsighted +1.0 to +4.0, including +2.75

Before you buy

Prescription lenses usually add two to three days of processing, and used lenses generally aren't returnable, so confirm your correction with your eye doctor first. These fit the Promate Sea Slender and Promate Pro Slender. Read Can You Dive With Glasses? Your Best Options.
