unintended effects
Interesting. I hope they continue to develop this idea. My first thought, though, was what about people who don't or won't wear glasses, or who can't afford expensive glasses and computers, but can use public computers? My second thought, almost immediately, was Carl Reiner's character in *The Jerk*. While these glasses likely won't cause cross-eyedness, like the glasses in that movie, it will be interesting to see what unintended effects these will have.
