If you are farsighted, a plus diopter prescription mask restores clarity across common underwater distances. Despite the name, these lenses are not only for close-up tasks. By bending incoming light so the focal point lands cleanly on the retina, plus diopters sharpen the whole scene in water, from gauges at arm’s length to your buddy a few meters away and distant reef details.

In water, objects appear larger and closer, so many divers choose a slightly lower plus power than their glasses. Start from your Sphere value, select the closest 1.0 step available, and set each eye separately if needed. Our tempered glass lenses provide sharp optics and resist scratches, while hypoallergenic silicone skirts help maintain a comfortable, leak resistant seal.

For smaller faces choose Rx Mako (0, +1, +2, +3, +4, +5; . For larger faces and different diopters per eye, choose Rx Action (0, +2, +3, +4, +5).
