The study in this chapter aims to assess the effects of degraded peripheral vision on visual performance. A series of preliminary psychological experiments were conducted to evaluate identification task performance in unrestricted viewing conditions in terms of the required time to identify a peripherally located three-digit number. This study is inspired by the case of decreased performance and discomfort of patients wearing corrective lenses with distorted peripheral fields. The experiments in the study involve three subjects whose head and eye movements were simultaneously recorded using an infrared reflection technique and an ultrasonic head movement monitor, respectively. A block diagram of a model to represent the task of identifying eccentric targets during restricted peripheral vision is constructed in this chapter. It is concluded that identification of peripheral targets when peripheral vision is restricted requires a coordinated and precise motor response from head and eyes.
