How do Transitions VI lenses perform in hot and cold temperatures (extreme temperatures)?
Transitions VI lenses are the best primary pair of lenses for everyday use. However, because of the laws of chemistry, the actual performance attributes (especially the level of darkness and speed of deactivation) of all photochromic lenses are normally affected somewhat by extreme hot and cold temperatures. The great news is that Transitions VI lenses get much darker in hotter temperatures than ever before.
