Your eyes have their own built-in protective reflex—even when you’re not thinking about them. 👀
When you close your eyelids, your eyes naturally tend to rotate slightly upward. Known as **Bell’s phenomenon**, this reflex helps position the sensitive front surface of the eye safely behind the upper eyelid.
It’s completely automatic and happens in a fraction of a second. One more tiny detail that shows just how sophisticated our visual system really is! 🧠✨
