A pair of glasses that can help blind people 'see' things has been developed by British scientists.
It works with the help of two small cameras hidden in the glasses frame, which are connected to a mini computer.
Every time the cameras spot an object, the computer lights up loads of tiny LEDs stuck onto the lenses.
The bright lights tell the wearer something is nearby, so they can avoid obstacles and find their way around.
A team from the University of Oxford is showing off the invention at this year's Royal Society Summer Science Exhibition.
