From a story on PetaPixel (https://petapixel.com/2019/07/05/goodbye-aberration-physicist-solves-2000-year-old-optical-problem/)
"You see, lenses are made from spherical surfaces. The problem arises when light rays outside the center of the lens or hitting at an angle can’t be focused at the desired distance in a point because of differences in refraction. Which makes the center of the image sharper than the corners. Which leads to countless YouTube reviews on lenses. And countless hours of watch time. And makes advertisers and YouTubers happy."
Anyway, some fella has finally solved a 2000 year old maths puzzle about this issue .... and it works. Great news for the future of lenses.
