New #metasurfaces, ultra-thin materials made of tiny #nanoantennas that can both amplify and control light in very precise ways, could replace conventional refractive surfaces from #eyeglasses to #smartphone lenses and improve dynamic applications such as augmented reality/virtual reality and #LiDAR.

My first time with eyeglasses with progressive lenses.

Guess it will take some time for the brain to adjust.

After some trial and error with eyeglasses I can say: Unless your eyes are worse than mine (and mine are very bad), expensive ultra-thin lenses aren't noticeably better than basic lenses. But OMG is anti-reflective coating key! My vision with the best anti-reflective coating is NOTABLY better than without any anti-reflective coating. So if you can only spend big on one thing, that's what to spend it on. #eyeglasses #glasses #vision
