What do you think is the difference for see vs look , hear vs listen? I think the former sets are passive, unwilling ones, while the latter sets are active, willing ones.
1. I can see everything!(a blind waking up after an eyesight recovery operation)- passive
2. Please take a look at it! - active
3. I heard the thunder - passive
4. I listened to his lecture. - active
I think you are right. See and hear are not passive in the grammatical sense but they indicate less activity than look and listen.
