I studied a little about lenses and I didn't come across this equation so could you tell me where did it come from is it derived from snell's law, could you tell me about it does it work for thick lenses. and by the way I tried to refract rays on a spherical surface so it's basically moving...

So if I want perfection I have to simulate a parabolic lens? but can I simulate a spherical lens with the aberration and still image formation works because all eye models are based on spherical lenses if not, can I an equivalent parabolic lens from a spherical one and what is the equation of a...

Hi guys I've been trying to make a program that simulates image formation in the eye so I simulated a spherical lens behavior in 3d coordinates and I'm facing a strange results! is it normal that the refracted rays don't intersect all at the same point I began to think it's true because of...
