Los Angeles The newly unveiled concept headgear that would superimpose graphics on your view of the world — immediately made me think of Steve Martin's glasses in The Jerk. The ones that made him cross-eyed.

With the new augmented-reality headgear, cool graphics pop up on a small screen a few inches from your right eye. Would those of us 40 and older have problems refocusing?

Suggestion box

Honestly, just thinking about it makes my head hurt. But it's early yet. Perhaps the middle-aged can request built-in progressive lenses — the virtual suggestion box, after all, is open. On Wednesday, Google launched its Google+ page for Project Glass: "We want to start a conversation and learn from your valuable input."

According to CNN, the product is far from finished, and Google only went public in order to gather feedback. A video on theGoogle+page shows how it might work. As The Times reported in February, the glasses may include a built-in camera to record what the wearer is looking at and then use that feed to find relevant information about what is being observed, which is displayed on the glasses' lens.

Among the technology that could be incorporated: motion-sensing capability, 3G or 4G wireless connections, GPS location services and Google Goggles' augmented-reality software. Goggles uses photos to conduct Web searches to find art, landmarks, books, etc.
