New Joe 90-style smart glasses that can monitor health and allow people to play video games just with their eyes have been invented by scientists.
The groundbreaking new technology will provide more advanced information than existing smart watches and will help diagnose medical conditions.
The devices – which also function as sunglasses – have been developed by researchers from Korea University in Seoul and rival those worn in the popular 1960s sci-fi TV series which help Joe 90 become a secret agent.
They will measure electrical signals from the brain or eyes and can be hugely beneficial in spotting conditions like epilepsy and sleep disorders.
