by not allowing the use of pseudonyms Google promotes an environment where deception is encouraged

Interesting paradox there, but I think you're right. If the stated rule is "Use Real Names" then you will assume that all the names you see online are those people's real, everyday names ... even if you yourself are using a made-up name. (There is a technical term for this, but I'm not a sociologist.)

I would think if you wore a "Google Glass" for even a couple hours your eyes would be affected

Someone grab the nearest passing ophthalmologist, because I was wondering this too. Physically the screen is, what?, an inch or so from your eye, although what you see is intended to look further away. (Try focusing on a speck of dust in your eye-- or a floater, if you're afflicted with them as I am.) Physiologically are you then working in extreme closeup, or are your eyes behaving as if they're looking at something a cubit away? The ads imply that you wear these things at just the times when your eyes would otherwise be focused on the mid-to-far distance, which is rare enough these days.

Oh, and then of course we'll have to get a fresh set of universally ignored laws to join the ones about driving while talking or texting on a cell phone...
