This is likely due to it being difficult for the pupils to dilate or constrict in response to light or darkness (Boyd & Bee, 2012, p. 397). The final visual difference mentioned was that she has become farsighted. She said she typically holds items, such as a newspaper, farther away to obtain an improved view of it. These changes are collectively referred to as presbyopia (Boyd & Bee, 2012, p. 396). Presbyopia is defined as the normal loss of visual perception, especially difficulty focusing on near objects (Boyd & Bee, 2012, p. 396). When questioned about differences in hearing she said, “I know I do not hear as well as I used to”. Normal hearing loss that occurs as one ages is called presbycusis (Boyd & Bee, 2012, p. 397). Another change in hearing my grandmother has experienced is tinnitus, or a ringing sound in the ears (Boyd & Bee, 2012, p. 440). My grandmother has worked in an office with persistent, loud sounds.
