What can your eyes see? If you can't even see the function questions on the blackboard clearly, then you will lose at the starting line! Here you can meet an old woman who can see your embarrassing history, an uncle who can see which cat cafe you frequent, and a little boy who can quickly identify whether you are S or M... Don't worry, you don't know their existence, but someone does. If we could see the specific abilities of all these visual people, wouldn't it be possible...
Intention: How to identify and use vision ability correctly as a kind of special ability, and how to gain the strength to move forward from the convenience and pain brought by vision ability.
