I'm sorry if you can't see
| my pupils; I have dark eyes 1. I can't feel my pupils dilate. In fact, there are no changes in my vision when that happens. 2. I don't because smooth muscle makes that happen. I have no control over smooth muscle, meaning that I can't control the dilation of my eyes. 3. It is called an involuntary reflex. This is because the definition of involuntary is something done without will or conscious control, like this specific reflex. 4. Our pupils get bigger in the dark to be able to take in as much light as possible, which helps us see. They shrink in the light, though, to not let our eyes take in so much light, which might result in a vision problem. 5. If our pupils didn't dilate when in the dark, we wouldn't be able to see in dark places. But if our pupils didn't contract in the light, we would probably be blinded when we look at something bright. |
