Q. The ciliary muscles in an eye change the focal length of an eye lens to focus distant or nearby objects clearly, this ability of an eye is known as the power of an eye.

Name the eye defect in which eye lens becomes cloudy or milky. Mention the method for its correction. A person uses a lens of power -1.0 D for correcting his distant vision and for correcting his near vision he uses a lens of power + 2.0 D. Calculate the focal length of the lenses required to correct these defects. Explain why a normal eye is not able to see clearly the objects placed closer than the near points.
