Orbicularis oculi

The orbicularis oculi is a circular muscle around your eye socket that helps control your eyelids. It allows you to close your eyes, blink, and squint, playing a key role in eye protection and tear distribution. This muscle also assists in removing tears from your eyes when you blink or blink rapidly. It is essential for facial expressions involving the eyes, such as expressing happiness, sadness, or surprise. The orbicularis oculi works with other facial muscles to facilitate these movements, contributing to non-verbal communication and maintaining eye health.
