The Eye doesn't spread the Coruption. The only way to have Corruption in you're World is either naturally, using Unholy Water (not sure if you can get that from the Dryad during a Blood Moon/Solar Eclipse in your world), or spreading it with Corruption blocks (Ebon stone, Ebonsand, Corrupted Grass, etc.). Th only way I know of that would definately spread the Corruption in your world is kill th WoF, get the Demonite bricks, and place it on grass.
