when something gets into our eyes and starts stinging, why does it hurt less when we close our eyes

In: Biology

Our body has thousands of nerves. These are like wires that carry information. It’s why it your hand burns when you touch a hot cup or you feel cold when you step out during a snowfall. So when you put, say some soap into your eye, your brain doesn’t know how to react, so it allows you to open your eye much wider hoping that would help, but that just adds on since it takes in too much light. Have you ever tried to look at a torchlight or car headlight from close up, it hurts and is blinding. So, immediately you close your eyes to cut that off. And now, only the soap inside your eye hurts, thereby reducing the total pain (momentarily, but it still pains) and will eventually wear off once you wash it with some water and make the pH normal

If the thing is something like soap then the tears trapped behind your eyelids will dilute it, if it’s an object like a piece of dust they’ll wash it off the surface of the eyeball. It may also be that the pain is a signal which says “close your eyes!”, so once they’re closed the pain is less necessary.
