Along with the aforementioned nose pads, there are two other important accessories in the box. One is the vital microUSB power cord, which has a nifty two-tone pattern.
At first glance, it looks like a simple black and white cord. But as the Glass team member pointed out, the plug was designed so that users wouldn't have to even think for one nanosecond about how the adapter connects to the cord -- just match the colors.
There is an important note about the power cord. Yes, it sports a standard microUSB interface -- but it doesn't charge the same way.
The simple story here is that you can use an older microUSB adapter you might have lying around from another device to charge Glass, but it will charge slower.
But the Glass team advised never using the adapter that came with Glass for a smartphone as it might fry the smartphone's battery altogether.
