Did You Know!
Your Eyes Have a Built-In “Cleaning System”
Your eyes naturally clean themselves every time you blink.
Blinking spreads tear film across the surface of the eye, which contains:
- Water to hydrate the eye
- Oils that prevent evaporation
- Antibacterial enzymes that fight germs
Humans blink about 15–20 times per minute, meaning your eyes are automatically cleaning and protecting themselves over 20,000 times a day.
This system is so effective that small debris or bacteria are usually washed away before you ever notice.
