usage
Often paired with 手快 (shǒukuài, quick-handed) as the set phrase 眼尖手快 — 'sharp eyes, quick hands', praising someone who notices and acts fast. Casual / spoken register.
memory
尖 means 'pointed/sharp' — the same character is used to praise other senses: 鼻子尖 (sharp nose, good sense of smell), 耳朵尖 (sharp ears, good hearing). The metaphor is 'pointed enough to detect what's small'.
