Google has patented a smart contact lens that could see its Glass wearable computer fit inside a smart lens.
The firm has already developed a contact lens for diabetics analyses their tears, warning them if their glucose levels are low.
Now it has revealed plans for a lens with a camera built in - opening the possibility of its Glass system being shrunk down significantly, offering features such as ‘superzoom’ to wearers and even helping the blind see.
According to PatentBolt, the system could even be used to help the blind see.
‘For example, a blind person wearing Google’s contact lens with a built-in camera may be walking on a sidewalk and approaching an intersection,’ it says.
