watch (someone or something) with an eagle eye(redirected from watched them with an eagle eye)
watch (someone or something) with an eagle eye
To observe very closely, without ever looking away. Like all birds of prey, eagles are known for their excellent vision. You've already been caught once, so you better believe the principal is going to be watching you with an eagle eye from now on. I've been watching that spot with an eagle eye, but still no sign of the leopard.
