Most of the concepts from Sections 5.1 to 5.1 appear in standard textbooks on sensation and perception [98,206,358]. Chapter 7 of [206] contains substantially more neuroscience than covered in this chapter. More details on photoreceptor structure appear in [52,229,345]. The interface between eyes and engineered optical systems is covered in [301], of which digital optical systems are also related [158].
Sweeping coverage of eye movements is provided in [186]. For eye movements from a neuroscience perspective, see [179]. VOR gain adaptation is studied in [59,92,289]. Theories of microsaccade function are discussed in [273]. Coordination between smooth pursuit and saccades is explained in [74]. Coordination of head and eye movements is studied in [164,251]. See [17,250,294] regarding comfort issues with vergence-accommodation mismatch.
