(Science Magazine) Ever wonder what it’s like to have an “eagle eye?” Surgeons and spies alike may soon find out, thanks to a new camera lens that works the same way eagle­—and human—eyes do, despite being no bigger than a grain of salt.

With spy gadgets in mind, scientists started working on the microlens a few years ago, but this new version features improvements to the lens’s field of view and focusing ability. Their latest version—cast in plastic with a 3D printer—acts like an eagle eye, they report today in Science Advances.

The camera uses four lenses instead of one, each set at different focal lengths and mounted on an image-reading microchip that compiles data from all four lenses into a single image.
