One eye smaller than the other. Is this normal?

A while ago, someone pointed out that I had a wonky eye and it's been bothering me ever since. My eyes are positioned correctly, it's just that one of my eyes is slightly smaller making it look like my eye is wonky. To make it worse, on the eye which is smaller my lashes droop more then my other eye. It's a real pain and it makes me conscious about how I look. I can't even wear eye liner lol. Is there anyway I can make both look equal?
