In this episode, we talk about shooting glasses which is a big topic of conversation in our sport, and do you need as many lenses as you think you do.  Dr. Colo explains the Purkinje effect which is sometimes called the Purkinje shift.  If you are wondering that is.....it is the changes in perception of the relative lightness and darkness of different colors as illumination changes.  

If you are interested in seeing Dr. Colo, he tells us where he will be in the upcoming year and how to contact him.
