Mom's Eye
Effect
- Gives Isaac a chance to shoot a tear out of an eye on the back of his head.
- (Removed in Repentance) The chance is 50% at 0 Luck, increasing by 25% per luck. This maximizes at 100% at 2 luck and minimizes at 0% at -2 luck.
- (Added in Repentance) The chance is 50% at 0 Luck, increasing by 10% per luck. This maximizes at 100% at 5 luck and minimizes at 0% at -5 luck.
- (Added in Afterbirth) This item belongs to the Yes Mother? set. Collecting three items from this set will transform Isaac into his mother.

- (Added in Repentance) Eye of the Occult: Mom's Eye tears follow the direction in which Isaac is shooting.
- Loki's Horns: Any time Mom's Eye would activate, Loki's Horns activates instead.
- Rubber Cement: Tears bounce around, making the backward tear more likely to hit enemies.
