Bigatmo Tropo 0051 feature advanced Zeolite (grey) S14 High Contrast Narrow Band (HCNB) grey lenses which have been developed using advance Light Management Technology to make colours come alive. HCNB technology allows your eyes to receive more specific colour information which increases the sharpness and clarity of an image whilst reducing eye fatigue.

Pilots will testify that Bigatmo sunglasses with Zeolite (grey) S14 HCNB lenses:

  • Allow you to read instrumentation in high-contrast environments
  • Help your eyes remain relaxed and reduce eye fatigue
  • Deliver true colour perception and landmark clarity
  • Remain comfortable for many hours whilst wearing a headset

How do the Bigatmo Zeolite (grey) S14 High Contrast Narrow Band lenses work? Bigatmo Zeolite (grey) HCNB lenses are superb for high contrast environments, such as flying and driving. Our eyes detect colour using ‘cones’ on the retina. HCNB technology filters out the wavelengths between the three primary colours and so optimise the wavelengths that enter the eye. Our eyes are most sensitive to wavelengths in the green spectrum, and wavelengths in the blue range cause visual clutter, loss of contrast and eye fatigue. HCNB technology manages the light as it passes through the lens allowing your eyes to remain relaxed.

Bigatmo Zeolite (grey) S14 High Contrast Narrow Band lens technology:

  • HCNB Light Management technology makes colours come alive
  • Reduces visual clutter by filtering out the wavelengths between primary colours
  • Optimises the wavelengths that enter the eye reducing eye fatigue
  • Increases sharpness and clarity of an image
