Figure 1: Clinical protocol. Repeated-measures ANOVA of the Objective Scatter Index (OSI) was performed for two different blinking patterns: blinking every 2.5 seconds (high BRs) and not blinking for 9 seconds (low BRs). The graphic representation of OSI values for high BRs was recorded over 20 seconds. Successive intervals were registered separated by blinks, and the graph represents a stability model of the OSI value with a flat curve. The graphic representation of OSI values for low BRs was recorded over 9 seconds, and only one interval was registered and analyzed. The distribution of OSI values over time has different behaviors: case #1 represents a stable model with a flat curve, while case #2 represents a model of instability with an increase in the slope of the curve. Measurements were performed for each visit (baseline, Day 1, and Day 15) using randomly assigned contact lenses. OSI: Objective Scatter Index; dyn.: dynamic; BR: blink rate; CL: contact lens; w CLs: wearing contact lenses; sc: seconds.
