When changing or replacing contact lenses part way through the day does not improve discomfort - a new study explains why

An interesting study was published in the October 2013 issue of Optometry & Vision Science.  It addresses a situation well known to many contact lens-wearers. Over the course of a day of contact lens wear, discomfort increases for some people.  And for some of these people, changing or replacing the lens to a fresh lens part way through the day does not help. Why is that?  This study may have an answer and suggests that it is not the lens, it's physical changes happening on the surface of your eyes.
