The Motion of a Contact Lens over the Eye During Blinking

Key Points

• To estimate the motion of a hard contact lens on the eye's surface during blinking.
• Developed a simple model to analyze contact lens motion.
• Estimated initial motion as the eye opens.
• Compared model predictions with existing experimental data.
• The model provided estimates that were consistent with experimental results.
• Significant initial motion of the lens was observed during blinking.
