I can consciously make my pupils in my eyes smaller and bigger, its small but people can see me do it. Why can I do that?

Pupils only change size according to how much light the eye is dealing with. I don't think you can do that.

Well I can.

Don't mean to scare you abby, but the only time that happens is when there is some kind of disease present.

Really? What disease is that? :/

Did it take you that long to come up with a response because you didn't want to let it go. Give me a minute I'll find some for you. One in particular is a stroke symptom which effects the dilation (but I don't think you are quite old enough for a stroke) and/or diabetes which doesn't discriminate, and oh yes, drug overdose will effect he dilation of the pupils and/or marijuana usage.

Hmm well, I'll look into it, thanks.
