Droopy eye

Morning all,

I woke up this morning with a really droopy right eye. I thought it might be sleep puffiness gone mad, but its not gone off.

I’ve never had this happen before, and am wondering whether I should do anything about it, or leave it a day or two and see if it resolves? There’s no pain, and no change to my vision, although it is my weak eye, and I’ve had ON in both in the past.

Any thoughts?
