Hollis M3 Prescription Dive Mask (with Corrective Lenses)

The low profile Hollis M3 prescription dive mask is a twin lens rigid frame mask with extra clear glass lenses with great optical qualities. The lenses have a lower iron content compared to traditional dive mask lenses, reducing the green tint, which improves colours and visibility.

The mask fits many faces, but works especially well for small to medium sized faces.

This mask takes the following lenses:

• planos (standard glass lenses, no correction)
• negative diopters: -1.5 to -8.0
