IST Prescription RX Lenses for Pro Ear & Corona Masks

Quick answer: These are prescription lenses for IST's Pro Ear and M55 Corona masks, in tempered, scratch-resistant glass. Left and right are interchangeable, and they're sold one lens at a time.

Why it matters

Corrective lenses let nearsighted and farsighted divers see clearly without glasses. Since each lens fits either side, you can set up each eye with its own strength.

What you get

• Single tempered, scratch-resistant prescription lens
• Interchangeable left or right

Options

• Lens: Nearsighted -1.0 to -8.0 or farsighted +1.0 to +4.0, in 0.5 steps

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 IST M55 Corona and the IST Pro Ear mask (RX008). Read Can You Dive With Glasses? Your Best Options.
