The Spider Eye is a poisonous food and a brewing item. It is dropped by Spiders and Cave Spiders when killed by the player, but is not dropped by spiders that die from environmental damage (such as in a mob grinder). Spider Eyes are used to craft Fermented Spider Eyes for brewing mainly Potions of Weakness. It can be eaten, but will poison the player for four seconds, causing 2 hearts of damage. This damage cannot kill the player. (It cannot reduce health below ½ a heart).

The Spider Eye's primary function in Tekkit is to make Grin Powder by macerating the Spider Eye. Grin Powder, in turn, is used to make Weed-EX for Cross Breeding.
