We do offer photochromic or transition lenses. 

Transitions can be a good option for some people. Axon Optics photochromic lenses are Indoor lenses that darken to light Outdoor lenses when exposed directly to UV light. They darken outside and double as a pair of sunglasses, although they will not be as dark as a traditional sunglass lens.  The darkening element within the lens won’t impede your regular vision, indoors or out. 

However, it is important to know that photochromic lenses only darken when directly exposed to UV light. They do not darken in bright indoor light or inside cars. These lenses are more reactive in cold weather. Indoor temperatures and warm outdoor weather will be slower.

Transition lenses are an additional $100 charge and are not kept in stock usually, so they can take up to 2 weeks to make and ship.
