  • Nearsighted/Shortsighted (Myopia)

    If things in the distance look blurry, like coral reefs, fish, or boats, you’re likely nearsighted. Our minus (-) prescription lenses bring far-away details into focus, so you can see the underwater world clearly while still keeping close-up vision sharp.

  • Farsighted (Hyperopia / Presbyopia)

    If you see clearly far away but struggle to focus on things up close, like your gauges, camera, or the fish right in front of you, you’re likely farsighted.

    Our plus (+) prescription lenses help bring everything into focus at once, making it easier to see clearly both near and far underwater.
