Answer to Question #90076 in Optics for Shivam Nishad

Question

Discuss the terms accommodation and
convergence in the context of image formed by
human eye.

Answer 1

Accommodation is a physiological process of changing the refractive power of the eye during the visual perception of objects that are at different distances from it.

The change in the optical power of the eye occurs due to a change in the curvature of the lens.

Eye convergence is the reduction of the visual axes of both eyes while fixing the gaze on closely spaced objects. When this occurs, the constriction of the pupil. The convergence of the eyes is carried out reflexively in the process of binocular vision.
