* Shielding from Debris: Eyelashes act as a physical barrier, catching dust, dirt, sand, insects, and other airborne particles before they can enter the eye.
* Reducing Airflow: Eyelashes help to reduce the airflow over the surface of the eye, preventing excessive evaporation of tears and keeping the eyes moist.
* Blocking Sunlight: Eyelashes can partially block sunlight, reducing glare and protecting the eye from harmful UV rays.
* Triggering Blink Reflex: When an object touches the eyelashes, it triggers the blink reflex, causing the eyelids to close quickly and protect the eye from potential harm.
In essence, eyelashes are crucial for maintaining eye health and preventing irritation or damage.
