SmartEyeglass was announced last autumn and now the company said it is ready to sell in 10 countries including the US, UK, Japan, and a number of European countries.

A kit costs $840, 670 Euros, 529 GBP, or 100,000 yen, depending on where you live.

Sony's SmartEyeglass looks like a pair of glasses with thick frames. But the lenses are also displays. They're 85 percent transparent, allowing you to look through the glass to see what's on the other side. You can also see text, monochrome images, or other content displayed on the glasses without shifting your gaze.

The Developer Edition hardware includes a 3MP camera with a CMOS image sensor, a gyroscope, accelerometer, electronic compass, and brightness sensor.

It is connected to an Android smartphone over Bluetooth or WiFi and it can communicate with apps running on your phone.

It can also tell you where you are by accessing your phone's GPS receiver.

A separate controller is attached to the glasses by a wire, and includes the battery, a speaker, a touch sensor, microphone, and NFC.

If Sony releases finished hardware it could have different features, a different price tag, and possibly a less clunky-looking design. However SmartEyeglass is already about half the price of a Google Glass Explorer Edition kit.
