Why Do We Blink?

The video explains why we blink, highlighting that blinking is a reflex action that protects our eyes. Reflexes are automatic actions our bodies perform without conscious thought, like breathing. Blinking helps keep our eyes moist and free from dust and dirt. Tears, produced by lacrimal glands, play a crucial role in eye health by washing away irritants and containing substances that kill bacteria and viruses. The video emphasizes the importance of blinking in maintaining eye health and suggests a fun blinking contest.
