the diffraction limit of a lens cant really be circumvented optically, it’s a fundamental limit of light due to being waves. so some insane refractive index wont help.
but elves are magical, so what if their eyes don’t care about the physical nature of light and just sorta convert it to magical pseudo-light when it contacts their tissue?
What if the refractive index of elvish eyes were somehow absurdly high? Paired with a very high resolution and sensitivity retina of course.

that’s not really relevant to the question at hand. “but magic” is clearly not an interesting answer when people are playing around with physics.
