Prescription Lens Options: Clear Vision Underwater

 

For divers with nearsightedness, masks that support custom prescription lenses offer a game-changing advantage. The lenses are available in a wide range of prescriptions, typically from -1.00 to -8.00 diopters (in -0.50 increments), including:

 

-1.00 / -1.50 / -2.00 / -2.50 / -3.00 / -3.50

-4.00 / -4.50 / -5.00 / -5.50 / -6.00 / -6.50

-7.00 / -7.50 / -8.00

 

These lenses are also made from tempered glass, maintaining the same high standards of safety and impact resistance as standard lenses.

Note: Due to the magnifying effect of water, divers are generally advised to choose a prescription that is slightly lower than their regular eyeglass prescription. This compensates for the natural magnification that occurs underwater and helps maintain optimal visual clarity.

Face-Hugging Waterproof Design – The ergonomic seal design ensures the mask remains leak-free during any type of movement, dive depth, or current strength.

 

Transport Case – Many models come with a dedicated silicone or EVA case that protects the lens and frame during travel and storage. This minimizes the risk of scratches, pressure damage, or environmental wear.
