Calculate maximum power of accomodation of normal human eye
  • 1 answers

Yogita Ingle 6 years, 4 months ago

  • The ability of the human eye to adjust itself such that it can see objects which are nearby and faraway is called Accommodation.
  • It primarily involves the lens and ciliary muscles.
  • The ciliary muscles are capable of modifying the curvature of the lens and thereby affecting the focal length of the lens.
  • When viewing objects which are nearby, the ciliary muscles contract, the lens becomes thicker. It is squeezed into a more convex shape and the focal length decreases (curvature increases). The images again falls on the retina. Note that here the eye is 'accommodating' by taking a thicker shape so that the image falls on the retina.
