Think you're too tired to drive? A new technology may help you decide whether to get behind the wheel or take a nap instead.

Japanese researchers say they have developed glasses that sense the user’s level of fatigue.

The eyeglasses track eye movements and transmit the data to smart phones.

They are designed to help people know their level of fatigue.

The product is expected to help reduce car accidents. The glasses will be on sale in Japan next spring.
