Why do some people eyes stay wide open when they are unconscious or after they are dead?

Answer:
No purposeful muscle control.

Maybe rigor mortis. Not enough energy to power the muscles that close the eyelids

---

Because they forgot to close their eyes while becoming unconscious or while dying

---

Becausee the muscles stop working, and that's why you usually see on the shows that people close the eyes. Because then if they have their eyes wide open, well ,it's a little bit creepy.

---

Because they struggled to stay alive or concious?
