Scuba masks and swim goggles

Swim goggles or scuba masks can also be manufactured with corrective lenses, providing clear vision under water for non-emmetropic eyes. To achieve optimal visual acuity, the “normal” dioptre values must be converted since water has a higher density and refractive index (n=1.33) than air (n=1.00).

Swim googles are mainly used for orientation whereas scuba masks are needed to see small details under water. For a clear underwater experience, it is necessary to clarify the intended purpose in advance: is vision correction required for orientation under water or on surfacing?
