11:21 AM Fri Jun 4 * 77% 4 YYY c) When the muscles connected to the crystalline lens relax, the focal length is 9.0000 cm. With this focal length, how close must an object be to form sharply focused images on the retina? (Note: this distance is called the near point of vision.) d) As people age, the crystalline lens hardens (a condition called presbyopia or "old-age" eyes) and can only vary in focal length from 12 to 15.60 cm. Calculate range of vision (the new near point and far point) for this older eye. e) Based on part d) why might an older person hold the newspaper at arm's length to read it? f) The iris of the eye serves two different purposes. First, the iris controls the total amount of light entering the eye so a person can see in varying light levels. Secondly, the iris blocks light from hitting the extreme edges of the crystalline lens. Why might an eye want to block the light hitting the extreme edges of a lens? What is the name for the effect when light does hit the edges…
