How dark can Transitions lenses get?
Transition Brown lenses achieves a level of 15% transmission having that be a tint of 85% and a Transitions Gray lens achieves a level of 12% transmission, having that be a tint of 88%. These are achieved at 72 Fahrenheit and will vary with recapture and air conditions; slightly darker in colder temps and lighter in warmer temps, also air quality can diminish the color by restricting the amount of UV just as snow can increase UV by reflection, thus making the lenses darker.
