When you blink is it cleaning your eyeballs?

Yes, blinking does help to clean your eyes.

- Tears: Blinking helps to spread a tear film over the surface of your eyes. This tear film keeps your eyes moist and lubricated, which helps to remove dust, dirt, and other foreign objects from your eyes.

- Oils: The tear film also contains oils that help to slow down the evaporation of tears. This helps to keep your eyes from becoming dry and irritated.

- Antimicrobial peptides: Tears also contain antimicrobial peptides that help to protect your eyes from infection.

- Mechanical action: The act of blinking also helps to massage your eyelids and stimulate the production of tears.
