The recently launched James Webb Space Telescope (JWST) is set to help rewrite our understanding of the cosmos. Already, astronomers have looked further back into the early universe than ever before — and crucial to the telescope capturing light from over 13 billion years ago are its massive mirrors.
The primary mirror, with its iconic hexagonal shape, is more than two stories in diameter and consists of 18 separate segments. All of these segments must be perfectly smooth, flat and scratch-free so as to provide a flawless image of distant astronomical objects.
Now these mirrors, developed over a decades-long effort by NASA, are helping eye surgeons improve the vision of millions of people by enhancing the accuracy of laser-assisted (LASIK) eye surgery

My Mom a few years back had laser surgery on Her eyes and the results was She no longer needed glasses at all. She read a lot and was always doing gardening and crafts so eyesight was very important to Her. She made it to age 92 but it was breast cancer that got Her but then She was never giving up and went outside and walked fast and kept moving and rarely sat still.
