MARKER DUAL BIONOMIC lenses are designed in a double-lens construction with an integrated thermal blocker. All lenses are oriented toward the curvature of the human eye to ensure that objects seen through the goggles look the way they really are. Unlike traditional, non-progressively tapered standard lenses, our lenses feature Bionomic Curve Lens Technology (quality class 1, ANSI Z87.1) that deliver undistorted light beams directly to the eye, which ensures 100% correct vision that doesn’t strain the eye.
Exterior lens (1)
Depending on the goggles model, various materials are used to produce the exterior lens: all standard lenses are produced from robust polycarbonate and enhanced with an extremely scratch-resistant coating. They offer 100% UV A/B/C protection up to UV 400 nm. The polarized lenses on the high-end models are produced from TAC (Tri Acetate Cellulose). This makes them ever lighter, clearer and more scratch resistant. TAC lenses offer world-class visibility as well as 100% UV A/B/C protection up to UV 400 nm.
Inner lens (2)
The inner lens is made of acetyl cellulose and is compression molded against the spherical outer lens as part of a heating process. This ensures that the shapes are congruent for 100% undistorted vision. The anti-fog and anti-reflex coatings are ‘embedded’ in the lens to prevent them from rubbing off over the long term.
Thermal blocker (3)
The interior lens also functions as a thermal blocker, creating an air barrier between the external and interior lenses. This thermal blocker compensates for differences in the temperatures, with the interior of the goggles constantly warm and dry – and fog-free.
