Which component of the eye has a maximum refractive index –
Anterior surface of the lens
Posterior surface of the lens
Centre of the lens
Cornea
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.
