Can you tell when someone's been crying?

So, not my proudest moment, but I cried a lot last night, woke up with puffy eyes. I didn't have to see anyone until 1pm and after make-up but I felt like my eyes gave it away. Someone I saw at 4pm straight away asked what was going on with my eyes that they were a crazy bright green. I just Skyped my parents and my mother wanted to know if I had bags under my eyes. The things people have said have never indicated a sign of crying. So can you tell if someone has been crying the night before? Anyone else's eyes change color when they cry?
