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.
PD stands for pupillary distance which simply means the distance between your pupils. In order for our glasses to perform at their best, we need to create prescription eyeglass lenses that can match the distance between your eyes, so the center of each lens aligns with the center of your pupils. For this reason, we need your pupillary distance measurement â also known as the PD measurement.
