Abstract The purpose of this study was to investigate whether forceful blinking would increase Meibomian gland secretion and lipid layer thickness (LLT). A specular reflection microscope connected to a color video monitor allowed observation of both the static and dynamic appearance of interference colors of the lipid layer before and after lid action. Evaluation of 104 subjects was made under three different conditions: during habitual blinking; with fixation directed at a target without blinking; and with forceful blinking. Quantification of the lipid layer thickness for all three conditions was provided by observation of the specific colors. The results included: 1) significant individual differences, both in baseline LLT and in LLT following forceful blinking, occurred; 2) the findings were repeatable on different days; 3) three forceful blinks resulted in a mean LLT increase of 33 nm for subjects with baseline LLT's of 75-150 nm, and a mean LLT increase of 19 nm for subjects with baseline LLT's of less than 75 nm (p A MINIMAL RESISTANCE MODEL OF MOTION INDUCTION
