How long does it take for photochromic ski goggles to transition?

Most modern photochromic ski goggles transition from light to dark in approximately 30–60 seconds and from dark to light in 45–90 seconds. The darkening reaction is typically faster than the lightening reaction. Cold temperatures below -10°C (14°F) can slow the lightening reaction noticeably. While not instantaneous, the transition is fast enough for most on-mountain weather changes, which tend to be gradual rather than sudden.
