Face the spot where the item is buried and click A, or use the Item Finder on top of the spot.
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.
Find snorlax then stand in the exact spot where it was then use the itemfinder and you will dig up a item it is the leftovers.
Once you have the itemfinder and pokeflute go to the top of Pokemon Tower which is in Lavendar Town, once your at the top stand in the spot where Mr Fuji used to be and use the itemfinder if your in the right spot you should dig up a Soothe Bell item.
The itemfinder will point you in the direction of where hidden items are press A in that direction to find the item.

The itemfinder works when it finds a secret item around your current area for example on One island if you go south you can reach a treasure beach using the itemfinder you can spot hidden items and dig them up. Also if you use it where snorlax and Giovanni and mr fuji used to be you will find super secret items.
after you have found something you need to dig under
press A on the space
Well firstly you obtain the itemfinder from prof oak's aide if you have about 30 Pokemon (I'm not sure) in vermillion to the far east. (The guard house if i could call it that). Now a fine example of using it is when your in a underground tunnel. First you go on your items menu and just click itemfinder then use. It would respond either "Yes itemfinder is responding" or "Nope, itemfinder isn't responding". How to get the item is quite simple, just face the ground where you think the item is and hit a and you should get a item, unless your wrong. I think the itemfinder has a range of four squares around you (one square is one of your steps)
Press use to use the itemfinder and if it dings you have found something. Walk in the direction you are facing then use the itemfinder again. continue until the itemfinder starts shaking wildly and press A facing the spot and you will find something.
There is not an "item finder" in Ocarina of Time
The itemfinder only works when there is a secret item around the surrounding area try using it where snorlax used to be after you woke it up and caught it/defeated it you will find an item called leftovers.
