If this was posted elsewhere, my apologies for the redundancy. But I found this article about a solution for Spherical Aberration quite intriguing. A tidbit:
To the average person, that equation is probably just more confirmation that a career in physics and mathematics wasn’t for them. But for lens makers, it can provide an exact blueprint for designing a lens that completely eliminates any spherical aberration. It doesn’t matter the size of the lens, the material it’s made from, or what it will be used for, this equation will spit out the exact numbers needed to design it to be optically perfect.
