How it works: This test measures hand-eye coordination and simply requires you to throw a tennis ball against a wall and succeed in catching it each time. How to do it: Stand three feet away from a smooth and solid wall. Throw the ball with one arm, in an underarm action at the wall. Catch it with the opposite hand as it bounces back at you. Throw it back at the wall with that hand and catch with the opposite. Repeat. Time how many successful catches you achieve in 30 seconds. Did you find challenging? What factors may affect your performance? How do you think eye- hand coordination can be improved?

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…
