This filter is photochromic starting at a 65% density in lower light and transitioning to full glacier density in cooler, brighter conditions. An excellent extreme exposure lens with some flexibility for other applications such as driving or more pedestrian activities. The McKinley Contrast is available for active sport applications involving faster speeds where a lighter higher contrast starting point and a little lighter endpoint are desired.
