If Oda was inspired by Popeye when creating Luffy, then imo it is very likely that Luffy is the eyepatch pirate that Oda said would appear near the finale of one piece.
In an interview, Oda said that the reason he hasn't drawn a single pirate with an eyepatch yet is because he is saving it for a certain character who will appear near the end of the series. I believe this character will be Luffy.
If Luffy lost an eye, he would be a one eyed sailor man, just like Popeye. Furthermore Luffy losing an eye would parallel him with zoro and if his eye is clawed out, either by kaido or Teach's claw weapon, then it would also parallel him to shanks, who similarly has a claw scar on his face.
I think that while zoro is missing his left eye, luffy will lose his right eye.
