F. ACCOMMODATION OF THE LENS 1. The lens changes its shape (accommodation) according to the distance of the object. The figures to the right show how the lens accommodate in response to a distant and nearby object. Examine the figure then answer the questions that follow. What happens to the shape of the lens in each case? 2. What is the name of the muscle that allows the lens to accommodate? Ans: ciliary muscle 3. Name the three pairs of extrinsic muscle that move the eyeball. 4. The focal plane is where the image is captured in the eye. How do the focal planes differ between the emmetropic (normal), myopic (nearsighted), and hyperopic (farsighted) eyes? 5. How does contemporary life affect the accommodation of the lens and therefore our vision? Think about the types of things that we do now that our evolutionary ancestors did not. D Focus
