Cressi Big Eyes Evolution Prescription Dive Mask – Gauge Reader

The Cressi Big Eyes Evolution Prescription Dive Mask – Gauge Reader combines Cressi’s famous panoramic visibility with positive corrective lenses designed to improve close-up vision underwater.

It is ideal for divers who can see clearly at distance but need extra magnification when reading a dive computer, pressure gauge, compass, camera display or other small equipment during a dive.

The positive correction is located only in the lower section of the lens, creating a practical bifocal-style viewing area. Look straight ahead through the standard upper section for normal distance vision, then glance down through the corrective section when checking your instruments.

Positive Gauge Reader Lenses for Close-Up Vision

Genuine Cressi positive optical lenses are made from high-quality optical glass and are available from +1.0 to +3.0 dioptres in 0.5 increments.

Each lens is selected individually, allowing you to choose different strengths for your left and right eyes where required.

This makes the mask especially useful for divers who need near-vision assistance underwater without requiring full prescription correction across the entire lens.

Positive gauge reader lenses can help make it easier to view:

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

Bifocal-Style Underwater Viewing

Unlike a full prescription dive mask, the Cressi gauge reader lens keeps the main upper viewing area non-prescription.

The positive corrective section is positioned lower in the lens, where it is naturally used when glancing down at your wrist, console or camera.

This allows you to maintain clear general visibility while still having magnification available when you need to focus on close-up details.

Exceptional Panoramic Visibility

The Cressi Big Eyes Evolution is well known for its wide, open field of view.

Its lenses are inclined approximately 15 degrees and extend downward over the cheek area, positioning the glass closer to the eyes and significantly improving downward visibility.

Cressi states that this design provides more than 30% greater downward visibility compared with a traditional flat-lens mask.

This makes the Big Eyes Evolution particularly well suited to gauge reader lenses, as instruments can be viewed with less head movement.

Low-Volume, Lightweight Design

The inclined lens system helps reduce the distance between the eyes and the glass, creating a compact internal volume while maintaining excellent peripheral vision.

With an internal volume of approximately 115 cm³ and a weight of around 160 grams, the Big Eyes Evolution feels light and streamlined both above and below the water.

Its low-volume design also makes the mask easier to clear and equalise.

Dual-Density Silicone Skirt

The Big Eyes Evolution uses Cressi’s advanced dual-density silicone skirt to balance comfort, structure and sealing performance.

Firmer silicone provides support around the mask body, while softer silicone is used around the facial contact area to create a gentle and adaptable seal.

Different skirt thicknesses are used in key areas to improve flexibility and help the mask conform naturally to different facial contours.

The result is a secure yet comfortable fit suitable for longer dives.

Flexible Pivoting Buckle System

The mask features fully pivoting strap buckles mounted on flexible elastomer tabs.

This allows the buckles to move naturally with the strap and helps reduce unwanted pressure against the face.

Strap tension is transferred efficiently to the mask frame, helping maintain stability and keeping the lenses positioned close to the eyes for maximum visibility.
