Presbyopia is a condition in which a person loses part or all of their capacity to adapt to changes in visual acuity. Will she still need reading glasses after having LASIK to fix her far vision? Explain.
Three patients have suffered destruction of different portions of their visual pathway. Patient 1 has lost the right optic tract, patient 2 has lost the nerve fibers that cross at the optic chiasm, and patient 3 has lost the left occipital lobe. Draw a picture of what each person would perceive through each eye when looking at a white wall.

- Presbycusis is an age-related hearing loss affecting individuals over the age of 65. Many affected individuals have difficulty understanding words because, although they may be able to hear the sound, they are unable to distinguish the exact words. This hearing loss is most noticeable at higher frequencies. Which of the following statements correctly describes an individual suffering from presbycusis? Select one: a. Individuals with presbycusis have damaged hair cells at the base of the cochlea, which is closest to the oval window. b. Increasing the volume of higher frequency sound allows individuals affected with presbycusis to hear better. O c. Individuals with presbycusis have damaged hair cells at the apex of the cochlea, which is farthest from to the oval window. Od. Decreasing the amplitude of lower frequency sound allows individuals affected with presbycusis to hear better.arrow_forwardAlbinism is a condition in which melanin pigment is not made.
