Idk If It's A Sign Of Autism Or Anything But I Need To Talk About Something

Idk if it's a sign of autism or anything but I need to talk about something

You know the phrase "eyes can't lie" and I'm like, I visualize an eye, the globe and I'm like... You can't see anything in this. But then I understand that when people talk about the eye, they talk about eyelids, eyebrows, possible dark circles and I'm like that's not the eye, it's more than that. At this point u should just say that a face cant lie because the eyes are just organs. I don't understand, this doesn't make sense. If I talk about a tooth I'm not talking about my whole mouth

Am I just stupid ?
