What is visual accommodation
What is meant by the visual accommodation?
Expert
Visual accommodation refers to the mechanism of varying the curvature of crystalline lens in order to make possible the variation of its refractivity to adjust the images of the objects exactly onto the retina. The visual accommodation is achieved through the action of ciliary muscles. The nitid vision depends upon the visual accommodation as, in case the images are not projected onto the retina but in front or behind it, they will emerge as blurred. The closer an object is more the ciliary muscles should compress the crystalline lens; the more distant an object is more the ciliary muscles should relax.
