Google has claimed that children under 13 shouldn't wear Google Glass, the company's upcoming futuristic internet glasses.
The web portal's site says: "Don't let children under 13 use Glass as it could harm developing vision." The smart specs use voice control and let the wearer do things like take photos, make video calls and even look at websites, the BBC reported.
The wearable computers, which are expected to go on sale in 2014, are currently being tested on a group of 1,000 people. The website also says: "Glass isn't for everyone. Like when wearing glasses, some people may feel eyestrain or get a headache.
"Kids might break Glass or hurt themselves, and Google's terms of service don't permit those under 13 to register a Google account," it reads.
