This distinctive view of race is consistent across demographic subgroups of Latino adults. For example, 69% of young Latino adults ages 18 to 29 say their Latino background is part of their racial background, as does a similar share of those in other age groups, including those 65 and older.
Relative Afferent Pupillary Defect (RAPD) is a condition in which pupils respond differently to light stimuli shone in one eye at a time due to unilateral or asymmetrical disease of the retina or optic nerve.
IPD is also used to describe the distance between the exit pupils or optical axes of a binocular optical system. Pupillary distance (PD) also describes the distance between the two pupils, but is an optometric term used to specify prescription eyewear. The PD of a patient is used to specify prescriptive eyewear for that patient. The distinction with IPD is the importance of anthropometric databases and the design of binocular viewing devices with an IPD adjustment that will fit a targeted population of users.
