Meta-lens works in the visible spectrum, sees smaller than a wavelength of light
High efficiency ultra-thin planar lens could replace heavy, bulky lenses in smart phones, cameras and telescopes

Summary:
Researchers have demonstrated the first planar lens that works with high efficiency within the visible spectrum of light -- covering the whole range of colors from red to blue. The lens can resolve nanoscale features separated by distances smaller than the wavelength of light. It uses an ultra-thin array of tiny waveguides, known as a metasurface, which bends light as it passes through.

Neat! This sort of thing could have various applications in the setting from early in the timeline onward.
