A blind person can meet some one but can not see. When you see some one, you do not only meet but are also conscious of what is happening around you by using your eyes. So the difference is obvious:
I meet her at the cafe.= I (or A blind person) usually visit the café to meet her with a purpose.
I see her at the café= I usually visit the café to be with her for some time. There may or may not be any purpose but just to spend some time with her because I am conscious that it a safe/nice place..
