Bigatmo Zeolite High Contrast Narrow Band lenses use advanced Light Management technology to make colours come alive.

Our eyes detect colour using ‘cones’ on the retina. These cones detect red, green and blue in a similar way to how televisions generate colour. The idea behind HCNB is to filter out the wavelengths between these three primary colours and so optimise the wavelengths that enter our eyes. In fact, our eyes are most sensitive to wavelengths in the green spectrum, and we find wavelengths in the blue range fatiguing.

HCNB technology allows the eyes to receive more specific colour information which increases the sharpness and clarity of the image whilst reducing fatigue.

Normal Chromatic response of the eye: Eye sensitivity curves have wide overlapping areas between chromatic receptors, making it difficult to rapidly define chromatic contrast

Bigatmo Chromatic response: Our NXT® High Contrast Narrow Band lenses reduce the overlapping areas, improving chromatic contrast and reaction time
