Scientists invent a contact lens that allows you to blink to 'zoom in'.

Scientists at the University of California San Diego have invented a contact lens that allows the user to 'zoom' in there might be a new substitute for those who need help with sight, thanks to a discovery by some scientists. 
According to New Scientist, scientists at the University of California have created a new contact lense. It also works as simply as blinking to 'zoom in'.The soft robotic contact lens is controlled by eye movements carrying signals from the eye to the lens itself. It could potentially be used in the future for visual prosthetics, remotely operated robots, and even adjustable glasses. The new lens seems like something straight from a sci-fi movie!
