Crack my eyes open

[DisneyLand]

Hi.
Is it correct, in American English, to say "I cracked my eyes open?"
What about "I winced back?"- as in astonishment.
Thanks for your time.

Although I know more about British English than American English, I don't think that's right.
"I opened my eyes just a crack." is okay (meaning you didn't open your eyes wide).
If the intention is to indicate that you opened your eyes suddenly, then you might say. "My eyes shot open."
"I squinted at him" - would indicate that you had your eyelids partially closed while you were looking at 'him'.
I think a "blink" (both eyes) would be more an indication of astonishment than a 'wink' (one eye only).
