One who glances; a person or thing that takes quick looks or glances.
From glance (possibly from Middle Dutch or Middle Low German glanzen, meaning to glide or slide) + -er (agent noun suffix meaning one who does). Literally means 'one who glances.'
A 'glancer' is someone who rarely gives things deep attention—they're the opposite of a deep reader, and psychology has actually studied this type of person and how technology is creating more glancers in society.
