In the God of War series, Kratos can find Gorgon Eyes by looking in secret spots and opening hidden chests. Upon finding six (or five in God of War: Chains of Olympus and God of War: Ghost of Sparta), Kratos can make a sacrifice to the gods and increase his health meter, as well as heal any damage he may have at the moment. After Kratos finds a total of 18 Gorgon Eyes (15 in God of War: Chains of Olympus and God of War: Ghost of Sparta), he won't be able to find anymore as his health meter will be fully reached. In God of War: Betrayal, each single Eye increases the health level. In God of War III, only three eyes are required to increase Kratos' health.
