Objectives
Narrative objectives1	The primary aim of this study was, first, to analyze the degree of eyelid-closure functional change in spontaneous blinking at the brow lift simulation, and then to estimate potential risk factors predicting postoperative deterioration of the eyelid closure after brow lift surgery.
Basic objectives2	Others
Basic objectives -Others	Brow lift simulation was conducted and closed palpebral fissure heights, namely corneal exposures, in spontaneous blinking were measured using high-speed videography.
