DS doesn't seem to be able to open left eye as much as right - whats going on?

[Kewcumber]

Started yesterday and hasn't gone today. No other symptoms, no swelling, no redness. His left eye just looks smaller as if its not opening as much as the right.

Anyone seen this before?

Nope, but I would get him to a doctor, PDQ, if only for the reason that eyes are precious.

yes I'd already come to that conclusion - am taking him tomorrow. I'm very concerned but hoping it something not too bad.

It is probably nothing, he could have knocked it during the night on Sunday.

But better safe than sorry.
