Cressi Quantum Positive Prescription Dive Mask

The Cressi Quantum Positive Prescription Dive Mask combines Cressi’s advanced anti-fog mask technology with positive corrective gauge-reader lenses designed to improve close-up vision underwater.

It is an excellent choice for divers who can see clearly at distance but need extra magnification when reading a dive computer, pressure gauge, compass, underwater camera controls or other close-up equipment.

Positive corrective lenses are available from +1.0 to +3.0 diopters in 0.5 increments, with separate right and left lenses so each eye can be matched individually where required.

Positive Gauge Reader Lenses for Close-Up Underwater Vision

The Cressi positive optical lenses are designed specifically to improve near vision while scuba diving.

Also commonly known as gauge reader lenses, they make it easier to read small displays, gauges and controls underwater without sacrificing the comfort and performance of a premium dive mask.

They are ideal for viewing:

• Dive computers
• Pressure gauges and SPGs
• Compasses
• Camera screens and controls
• Dive slates
• Small equipment markings

Positive lens powers are available from +1.0 to +3.0 diopters, increasing in 0.5 steps.

Because the lenses are manufactured separately for the left and right sides of the mask, they are not interchangeable. If your prescription differs between your eyes, select the appropriate power for each side.

Advanced Cressi Anti-Fog Technology

One of the standout features of the Cressi Quantum Dive Mask is its patented anti-fog system.

Warm, humid air exhaled through the nose can normally rise towards the lenses and contribute to fogging. The Quantum uses a system of internal silicone membranes around the eyes and nose to redirect this warm air towards the outer skirt instead of allowing it to flow directly onto the lenses.

The outside of the skirt incorporates two small heat-exchange areas designed to help reduce the temperature difference between the inside and outside of the mask.

This innovative airflow and thermal-regulation system helps reduce moisture reaching the lenses, providing clearer underwater vision throughout the dive.

Enhanced Downward Vision

The Quantum features inclined lenses positioned to improve downward visibility.

This is particularly useful when using positive prescription lenses, as divers frequently need to look down towards their wrist-mounted computer, console, SPG or camera controls.

The compact lens positioning also helps reduce internal volume while maintaining a wide and natural field of vision.

Compact, Hydrodynamic Design

Despite incorporating its internal airflow membranes and external heat exchangers, the Cressi Quantum maintains a streamlined and compact profile.

Its low-volume construction places the tempered glass lenses close to the eyes, helping improve peripheral vision while making the mask easier to clear and equalise.

Selecting Your Prescription Lenses

The positive diopter value relates to the sphere component of your optical prescription.

If each eye requires a different strength, simply select the appropriate left and right lens powers separately.

If you are unsure which diopter strength is suitable, we recommend asking your optometrist which positive sphere value is appropriate for each eye before ordering.

Who Is the Cressi Quantum Positive Prescription Mask For?

This mask is particularly well suited to divers who have difficulty focusing on objects at close range underwater but do not require full-distance prescription correction.

It is an excellent option for recreational and experienced scuba divers who regularly need to read instruments during a dive and want the additional benefits of Cressi’s advanced Quantum anti-fog and low-volume mask design.

Combining clear close-up vision, excellent downward visibility and advanced fog-reduction technology, the Cressi Quantum Positive Prescription Dive Mask provides a practical and comfortable solution for divers who need reliable gauge-reading assistance underwater.
