Welcome back to Shady Business- The SPEX By Ryan Podcast. In this episode, we hijacked the Transitions Story Studio at Transitions Academy Orlando, to sit down with Mayara Castillo. She is a chemical engineer who has worked on developing various types of Transitions photochromic lenses. She enlightens us (see what I did there???) on some of the fascinating behind the scenes work that goes on and also how these high-tech, light controlling lenses really work.   Many thanks to The Red Havas agency Crew to make this impromptu podcast a reality!
