Nike MaxSight

These contact lenses filter out reflections caused by the sun and enhance contrast — details appear a bit clearer and colors pop more. Their red tint relaxes the eyes and lets them focus for longer periods of time. Some teams have been using them in Beijing but sadly for non-Olympians, the Nike MaxSight ($N/A) have been recently discontinued. Also, the intimidating look that a pair of demonic pupils has on the opposition is hard to overlook.
