Moisturizing the Eyes: Blinking spreads tears across the surface of the eye, keeping it moist. This is crucial for maintaining clear vision and comfort.
Removing Irritants: Blinking helps to remove small particles, such as dust, that can get into the eye. This protective mechanism helps to keep the eyes clean and free from potential irritants. https://whyblinking.com/
Resting the Eyes: Blinking gives the eyes brief periods of rest, which can help reduce eye strain, especially during activities that require prolonged focus, like reading or looking at a computer screen.
Nourishing the Cornea: Blinking helps to distribute nutrients and oxygen to the cornea, which doesn't have its own blood supply.
Lubrication: The meibomian glands at the edges of the eyelids secrete oils that are spread across the tear film during blinking, preventing the eyes from drying out.
