Abstract

INTRODUCTION: A previous study has suggested that fluctuations in the blink rates of women not taking birth control pills may be related to fluctuations in estrogen and progesterone levels in the body.

SUBJECTS AND METHODS: Average blink rates of two women were measured for five minutes per day over a complete menstrual cycle.

RESULTS: The first subject showed a significant decrease in blink rates at ovulation and during the beginning of week 1. The second subject did the exact opposite and showed an increase in blink rate during ovulation.

DISCUSSION: The pattern of the first subject suggests that there may indeed be a relationship between hormone levels and blink rates, but more research needs to be done to support this hypothesis.
