Scientists at the University of California San Diego have created a contact lens, controlled by eye movements, that can zoom in if you blink twice, according to a new study published by Advanced Functional Materials.

Sounds like something out of a sci-fi movie, right?

The prototype lenses can magnify objects up to 2.8 times and could someday be useful for patients with macular degeneration, a major cause of blindness and visual impairment in older adults.

“Even if your eye cannot see anything, many people can still move their eyeball and generate this electro-oculographic signal,” lead researcher Shengqiang Cai said to New Scientist.

The study added that the new tech could also be used in “adjustable glasses and remotely operated robots.”
