Can you blink your eyes in the water?

Yes, humans can blink their eyes in the water. Blinking is a natural reflex that helps keep our eyes moist and protected, and it works the same way in water as it does in air. When we blink, our eyelids close for a fraction of a second, spreading a layer of tears across the surface of the eye. This helps to wash away any irritants and keep the eye healthy.

Even though we can blink in the water, it is important to note that our vision is affected when we are underwater. This is because water is a denser medium than air, so light waves travel more slowly and are refracted (bent) as they enter the water. As a result, objects appear larger and closer underwater than they actually are. This effect can be disorienting at first, but most people quickly adjust to it.
