<prompt> Which component of the eye has a maximum refractive indexAnterior surface of the lensPosterior surface of the lensCentre of the lensCornea  <response>: Lens has maximum refractive index among the refractive structures of eye. The refractive indices of the successive layers of lens increase from the periphery towards the nucleus. Therefore :-Anterior lens cortex Refractive index is 1.386.Posterior lens cortex Refractive index is 1.386.Centre of lens nucleus Refractive index is 1.46.
