For the last 6 months or so I have had more people than I can keep count of coming up to me asking me 'what I'm on' because of my giant pupils. I'm getting a bit uptight about it because they are, indeed, huge, even in bright light. At their largest it appears my eye is almost entirely black with virtually no iris.

It's really starting to get me down a bit because of the sheer amount of comments, both from people I know and people I don't (i.e. a cashier in a shop will ask if I'm okay, what's wrong with my eyes etc.) and the fact that people are asking me what drugs I've been taking which, while perhaps funny at first is just irritating and somewhat alarming the 30th time.

They look like this almost permanently:

Why are they dilated now? Will they ever go back to normal?
