Answer 1

when we look far oject focal lenth of ciliary muscels of will increase.when object near the ciliary musceles  will streched




if u like comment thanks

Answer 2

Answer:

The process of seeing distant and close object on the retina of our eye is known as Accommodation.

Explanation:

Upon this see the objects kept at a distance more than 25 cm (the nearest visibility of our eye is 25 cm while the farthest is infinity then the muscles present behind our eye or ciliary muscles are loosened making the focal length maximum. Similarly when the eyes will shift view from near object to distant object the ciliary muscle tenses and focal length increase making it easier for us to see distant object with better clarity.
