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…

Trace the path of light from the time it enters the eye to the time it leaves the eye to travel to the brain. You should refer to your labeled eye diagram.
Problem: A patient with a refractive myopia cannot see objects clearly if they are further away than 10 m. To be able to drive safely and obtain his driving license, he needs to be able to clearly see objects up to 100 m away. In this problem, Pmin eye = minimum optical power of the patient’s natural eyes, Pmin combo = minimum optical power of the patient’s natural eyes + corrective glasses, and Pmin glasses = minimum optical power of the corrective glasses. Questions: What is the cause of the patient’s vision problems (i.e., his medical diagnosis)? What does this diagnosis mean for the patient? If the patient opted to purchase glasses, would corrective lenses create real or virtual images in the patient’s field of vision? Would the eye interpret images produced by the glasses as real or virtual images? What assumptions can be made about the size of the patient’s eyeball and their lens-retina distance (units of m)? Define the term far point. What is the patient’s far…
