Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
luscus, a, um, adj. [root luc of lux; with fundamental idea to glimmer; cf. Gr. λυγη, gloom], one-eyed: Le. Oculum ego ecfodiam tibi, si verbum addideris. Sc. Hercle qui dicam tamen: nam si sic non licebit, luscus dixero, Plaut. Trin. 2, 4, 64; id. Curc. 4, 2, 19: Appius cenabo, inquit, apud te, huic lusco, familiari meo C. Sestio: uni enim locum esse video, Cic. de Or. 2, 60, 246; Mart. 4, 65; Gai Inst. 3, 214: cum Gaetula ducem portaret belua luscum (of Hannibal), Juv. 10, 157: ambos perdidit ille oculos, et luscis invidet, id. 10, 228.
Hence, with one eye shut, i. e. taking aim, said mockingly of a statue: statua meditatur proelia lusca, Juv. 7, 128; half-blind, Mart. 9, 37, 10.
