Guardian eyes

Guardian eyes would be a new item that has a 1 in 4 chance of being dropped by a guardian and could be used in the eye of ender recipe alongside blaze powder and ender pearls, putting the eye in eye of ender and making more players take on the ocean monument. They could also be used to create a potion of sight, that would highlight every entity in your chunk, making it easy for example to find caves or hidden players. Additionally the elder guardian could drop and item like the elder guardian's eye which could be crafted back into 3 guardian eyes or placed down as some kind of Redstone powered block, maybe some kind of laser wall.
