●We are able to see the distant objects as well as the nearby objects clearly because our eye can focus the images of the distant objects as well as the nearby objects on its retina by changing the focal length of its lens. The focal length of the eye lens is changed by the action of ciliary muscles.●

When we focus on far off object, culinary muscles contracts. This leads to elongation and thinning of ciliary muscles. This increases its focal length and we are able to focus on far off objects.
When we focus on nearby objects, culinary muscles relaxes. This leads to contraction and thickening of lens This decreases the focal length and we are able to focus on nearby objects.l
I have also attached a simple diagram for better understanding.
