Most of the concepts from Sections 5.1 to 5.1 appear in standard textbooks on sensation and perception [98,206,357]. Chapter 7 of  contains substantially more neuroscience than covered in this chapter. More details on photoreceptor structure appear in [52,229,344]. The interface between eyes and engineered optical systems is covered in , of which digital optical systems are also related .
Sweeping coverage of eye movements is provided in . For eye movements from a neuroscience perspective, see . VOR gain adaptation is studied in [59,92,289]. Theories of microsaccade function are discussed in . Coordination between smooth pursuit and saccades is explained in . Coordination of head and eye movements is studied in [164,251]. See [17,250,294] regarding comfort issues with vergence-accommodation mismatch.
