What happens if and when Glass-like devices become common and glasses-wearing people like me get them with prescription lenses?
Because normal glasses help you see?
That's the wrong question. The right question is: How does law enforcement prove that Glass was distracting me?
I shouldn't have to prove my innocence. They should have to prove my guilt.
But, since it's still a criminal case, and right to trial by jury is still recognized, there is a guaranteed automatic appeal that you can invoke[2] if you aren't satisfied with the decision in district court (or magistrate court). You then get a "trial de novo"[3] or "new trial" in superior court (or district court if appealing from magistrate court). Once you get to superior court, that's where you get a jury and the whole bit. It's interesting to note that some people consider it a legal strategy to basically use the first trial as a chance to size up the State's case, so they can construct the best possible defense on appeal.
Not sure if CA has a similar notion or not, but just wanted to point out that, in at least some cases, the bar on traffic offenses is still ultimately "innocent until proven guilty" (as it should be, IMO).

"A civil infraction is violation of the law less serious than a misdemeanor, and which usually does not attach certain individual rights such as a jury trial."
That, along with the sheer inconvenience, cost, etc., is probably why few people bother doing this for traffic citations. It's easier to just pay your fine, accept the increase in your insurance premiums and go on your merry way. :-(
You're 16 and you get your license and you get a car with one seat, a speedometer, and a manual gearbox. You then can undergo additional testing/licensure that shows you can cope with additional distractions (passengers, radio, cupholder, tachometer, Google Glass). Trouble is, I don't think many people would go for that.
This does not mean, however, that it actually helps with safety, and that concern should probably dominate.
If you want to be distracted and watch some YouTube videos or whatnot, then public transit would love to have you.
