define power of accomodation. write the modification in the curvature of the eye lens which enables us to see the nearby object clearly

hlo friend
the answer to ur question is
the ability of the eye lens to adjust it's focal length too see the object located anywhere is called power of accommodation the eye lens see the nerby objects clearly with help of ciliary muscles. It is made possible because the focal length of the human lens can change i.e., increase or decrease, depending on the distance of objects. It is the ciliary muscles that can modify the curvature of the lens to change its focal length.
hope it helps
Power of accomodation is the ability of eye lens to adjust its focal length to form a clear image according to the rays coming from distant or close objects.
- If the rays are coming from distant objects, the focal length of the eye lens becomes large to form a clear image by focusing rays on to the retina.
- If the rays are coming from near objects, the focal length of eye lens becomes small to form a clear image by focusing rays on to the retina.
- For nearby objects, the curvature of our eye lens decreases to decrease the focal length and form a perfect image.
