Abstract
Background: The aim was to assess the variability of spontaneous blink rate (SBR) with and without a chin and forehead support.
Methods: Forty-eight healthy non-contact lens wearers, aged from 20 to 39 years, had five-minute video recordings made under ambient lighting of 350 to 400 lux, while directing their gaze to a distant target at head height. Half the subjects (group 1) were seated resting against the chair head rest and the other half (group 2) seated but with chin and forehead at a slitlamp. The first 35 blinks were analysed in detail.
