This item belongs to the Yes Mother? set. Collecting three items from this set will transform Isaac into his mother.

Continuum: Tears shot out of the back reappear on the opposite side of the screen.
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.
Mom's Knife: Another knife is permanently behind Isaac, able to deal contact damage. The fire chance is still affected by luck as usual.

20/20/ The Inner Eye/ Mutant Spider: No effect on the tears fired out of the back of Isaac's head. The chance to activate is checked per shot, not for each tear fired.
Dr. Fetus: Occasionally shoots a bomb backward. Not recommended, as self-damage is likely.
Doctor's Remote/ Epic Fetus: Chance for two airstrikes on opposite sides of Isaac.
Ipecac: Occasionally shoots an explosive shot backward. Not recommended, as self-damage is likely.
Incubus: No effect.
Kidney Stone: Adds a chance for tear barrage to fire from the front and back of Isaac. The kidney stone will only fire from the front of Isaac.
Lead Pencil: Adds a chance for tear barrage to be fired behind Isaac.
The Ludovico Technique: Adds a chance for tears to be fired in random directions from the main tear.
Monstro's Lung: Occasionally fires one red tear out the back of Isaac's head.
Tractor Beam: The backward tear is not affected by Tractor Beam.
The Wiz: The backward tear is not affected by The Wiz.

Mom's Eye's appearance was changed in Booster Pack #5.
The item is based on the adage that a mother has an eye on the back of her head, and is thus always able to see what her child is up to.
