Question

what do you mean by accommodation of the eye

Answer 1

Accommodation: In medicine, the ability of the eye to change its focus from distant to near objects (and vice versa). This process is achieved by the lens changing its shape. Accommodation is the adjustment of the optics of the eye to keep an object in focus on the retina as its distance from the eye varies.

Answer 2

Accommodation is the ability of the eye to change the focal length of the lens by changing the curvature of the eye lens. Accommodation allows the eye to automatically adjust focus from seeing things at a distance and "tune" it to seeing nearer objects.

All in all, accommodation refers to the ability of the eye to focus on different objects by changing its focal length.
