Question

what is power of accommodation and persistence of vision........ Reply fast

Answer 1

The ability of changing focal length by ciliary muscles is called power of accomodation

Answer 2

The ciliary muscles of the eye change the focal length and hence the curvature of the eye lens.They do it because the image-lens distance has to remain constant and equal to the size of the eyeball.This is the power of accommodation



The ability of the human eye to continue to see the image of an object even if it has been removed for 1/16 th of a second is the persistence of vision of the human eye
