Supply and demand- laser eye surgery and the military
There's a really interesting article in the NY Times about how the wide availability of corrective laser eye surgery in the Navy is affecting the application pools for the various postgraduate jobs. The big winners are aviation and special forces, both of which require perfect vision in applicants. They now select from a much larger pool. One loser is submarines, who used to get the glasses wearers but now have trouble filling their quota.
But don't worry- in 50 years, aerial combat will be perfomed drones, controlled by 10-year-olds on their PlayStation Xs-- and glasses will end up being cool.
