<prompt> Which component of the eye has maximum refractive index -Anterior surface of the lensPosterior surface of the lensCentre of the lensCornea  <response>: Lens has maximum refractive index among the refractive structures of eys. The refractive indices of the successive layers of lens increase from the periphery towards the nucleus. Therefore:- Anterior lens coex- refractive index is 1.386. Posterior lens coex -refractive index is 1.386. Centre of lensnucleus- Refreactive index is 1.46. Reference: AK khurana 7th edition
