With advanced spectrophotometry, GUNNAR’s lab technicians have the ability to study and analyze even the most difficult lighting environments.  Each part of the visible and invisible light spectrum can be measured and quantified.  To balance and optimize that lighting environment for the needs of the human eye, the GUNNAR lab techs then use a combination of iONik lens tints and i-FI coatings.  At any particular wavelength, they can amplify or attenuate the amount of energy allowed to pass to the eye, maximizing the total visual performance possible and engineering the light transmission profile to specific end-use applications.

benefits:
tints tuned to specific environments for maximum visual efficiency
captures and enhances “good” light to increase ocular endurance
reduces high energy visible light to speed visual recovery
enhances contrast for a sharper viewing experience
