Cross the Library to the left and you should find a Glass Eye on the floor near the left bookcase.
yes
You have to light the chandeliers first then you will find it at the left side of the library on the floor.
Get down from the last chandelier and use the crowbar on the chained door. This'll provide an easy exit for when you need to exit. Go to the left and you'll notice a glass eye next to one of the armors. Pick it up. http://blog.poptropicahelp.net/island-help/vampires-curse-island/vampires-curse-guide has all the answers!!!!
like that but its smaller in the room
Ok so there are two suits of armour right? Next to the one on the left side of the room (where the locked door is) is where the glass eye is. After you insert it into the TIGER not the lion it opens its mouth and gives you a key to the armour room after that don't ask me about the rest because I don't know anything about that I am quite stuck myself. . . LOL
Above one of the bookshelves is a lion and the lion has only one eye. Put the glass eye on the lion and the key will come out of the lion's mouth.
below the bookshelf
When you have lit the fire and all the chandeliers, there will be a glass eye on the floor. Put it back in the tiger head to get a key.
On the floor by the left book case in the Library
After you light all of the chandelers find a glass eyeball by a bookcase and put it in the lions eye and its mouth will open and the key will be inside.
