You have to use the itemfinder to look for the guy's glasses. You will find the black glasses once you find it with the itemfinder. Those glasses boosts the power of dark type moves. Although those aren't the glasses the person is looking for. So you'll get to keep them.
you have to use a itemfinder
Use the itemfinder then start pressing A everywhere.
the real glasses: you cant find them. if you show the blackglasses he depart from there. you find blackglasses with the itemfinder
Use itemfinder at the spot where he talks to you. find the black glasses and talk to him. you will never see him again.
Just find the itemfinder press A and select 'use' then you're using it!
Use the itemfinder in the area where the guy is. This will point out to you where the item (in this case, the glasses) is. You get the itemfinder from one of the times you beat May. NOTE: the glasses you find are actually called "blackglasses" and when you speak to the guy after you find them, he tells you that they're not his glasses and that his glasses aren't in that place after all. So in the end, all you gain is a free blackglassses.
use itemfinder and find the black glasses. u never see him again
Not sure what you mean by glasses, but if it has to do with itemfinder, just stand in front of the scanned item, and keep pressing 'a' until you get it.
If you go to the rusturf tunnel and go toward the exit that leads to verandturf town you should see a path to your left if you go there it leads to an area where 2 secret base spots are you can also find black-glasses using the itemfinder.
actually the man doesnt drop his glasses there all you find are black glasses. use the itemfinder. blackglasses increase dark type moves If you actually look at the man who lost them, their are glasses on his face.
if you use the itemfinder there will be a blackglasses item. show it to him and he will say that those aren't his glasses, and he will walk off
