What is Diopteric power of eye - and explain in detail?
Ans. is 'c' i.e., + 60D o In schematic model, the optical system of eye behaves like a combination of lenses.o The reduced schematic eye treats the eye as if it were a single refracting element consisting of an ideal spherical surface separating tw o media of refractive indices of 1.00 (air in external environment) and 1.33 (eye as a whole),o So, in reduced eye, the entire system (of eye) can be regarded as one lens writh one optical centre which lies in the posterior part of crystalline lens.o The diopteric power of reduced eye is + 60D, of which + 44D is contributed by cornea and + 16D by the crystalline lens.
