Question

what is meant by power of accommodation of the eye??

this question is for class 10th.......​

Answer 1

Answer:

Power of accommodation of the eye is the ability of the eye to adjust its focal length to form images of far and close objects clearly on the retina.

Explanation:

The ability of the eye to adjust its focal length to form images of far and close objects clearly on the retina.

As the eye adjusts its focal length it also changes its lens power.

The changes will vary depending on the position of the object.

This is made possible by the contraction and relaxation of the ciliary muscles of the eye.

For far objects, the focal length has to be large. So, the ciliary muscles relax thinning the eye lens. The image is then brought focus on the retina.

For near objects, the ciliary muscles contract, reducing the focal length and thickening the lens. The image is then focused on the retina.

Answer 2

Power of accommodation of the eye:

• The ability of the eyes to focus near and far objects is called power of accommodation.
• A eye can accommodate an object with adjusting the focal length of the eyes.
• When the focal length is adjusted, the object falls clearly on the retina and we can see the object clearly.
• The ciliary muscles on the eyes adjust the focal length of the eyes.
• There is certain limit for the focal length beyond that the eyes cannot be adjusted where the requirement of the lens arises.
