Here is the sentence:
"Just cross your eyes a little and it would be impossible for you to tell the difference between this and televised football."
The sentence is from a game app's description. I know the lexical meaning of the phrase "cross your eyes".
Verb 1. cross one's eyes - partly close one's eyes;
"The children squinted to frighten each other"
Synonyms: squint, squinch
However, I am not sure how it would fit here.
Let me make the context clearer. The sentence is about a game update that makes the mobile play so realistic that one cannot differentiate between the game and the real football.
