63- Which of the following regarding the lens is false: a- Focusing the image on the sclera. b- An increase in the opacity called cataract. c- ciliary contractions lead to focus images from near objectives. d- More flattened lens leads to focus image from far objectives.

Using the attached image of a diagram of an eye, lable what A, B, C, D, and E are of the following parts: 1. Retina: Pigmented layer 2. Retina: Photoreceptor layer 3. Choroid 4. Sclera  5. Retina

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…

11,Find the sclera, the tough outer covering of the eye also called the "whites" of the eye. Feel the sclera. Do you think this structure is designed for strength or clarity? Why?
