Is focal length of eye lens fixed?

Answer:
Even though the image distance i.e. the distance between the retina and eyelens cannot be changed a normal human eye can see distant objects as well as the nearby objects clearly. This is possible due to the power of accommodation. An eye can focus the images of the distant objects as well as nearby objects on the retina by changing the focal length of its lens. The focal length of the lens can be changed by action of ciliary muscles.
