Eye observation

[Karen Chuplis]

This is just something that has always caught my attention. I haven't 
read a lot about the actors but wondered if anyone had seen anything on 
it.

In SS Dan has a very noticeable one-eyed blink. There are many times 
where you see him blink and just one eye closes (it's really cute 
actually). I don't know if it's like a lazy eye or what. In the 
following films they seem to keep it out, but I actually noticed it 
again in either PoA or GoF (sorry, don't remember which). I had thought 
it might be something he grew out of, but obviously I think they edit 
around it. I'm not sure why. I, anyway, rather like it. It's different 
and well, somehow suits "Harry's" unique character. Anyone else notice 
this?
