Interestingly enough, I think a technology like this has to be monitored by professional sports--maybe not now, but I could see this type of technology being the new frontier in "cheating". It seems like the logical next step in performance enhancement. Imagine a display that could read the velocity of a fastball, measure the drop of a sinker, read a quarterbacks heart rate, or judge which receiver is the most open. A lot of players in professional sports already deal with technologically advanced contacts, though these are quite rudimentary and merely change the tint (Yellow and Red) to allow for athletes to see specific details much more clearly.
