Chris Bennett: Google glass could be coming to your practice soon

It's a quiet Tuesday morning,  shoppers scurry past the window to avoid the rain and the sound of  Smooth FM is drifting out of the staff room door, then a customer comes in clutching a Google glass to be glazed. What would you do?

Google glass  is one of those technologies that you have probably heard of, you probably have an idea of what it does but the detail is more than a little hazy. Basically think of Google glass as a head up display for a smartphone, a smartphone is a computer in your pocket.

Given Google glass is £1,000, many of the buyers are going to be older spectacle wearing types .That's where you come in.
