I took a look at the pic on your profile page and she is just BEAUTIFUL! She reminds me very much of my red merle Aussie except mine didn't have the white blaze on the face, her whole face was merled.
The blue spot on her eye is simply the result of her merling. It will probably change several times during her lifetime. It may get bigger, it may get smaller, but it will change during her lifetime. It's nothing at all to worry about, however. It is TOTALLY normal.

Thank you for your comments Red and Ghilly! I am hoping it is something normal! I just wasnt aware that eyes could change color once they got a bit older. I have seen in a pic (my profile pic here actually) that a small blue-ish dot appears on that eye, and she was 3 months old then. But its definitely bigger now. : ( I cant figure out how to post pics on here, so I will add some to my profile!
This is VERY common in Aussies, and actually in any breed that has merles. Sometimes part of the eye is blue and part of it is another color, and these colors can change as the dog ages. It's nothing to worry about. I love the red merles. My heart dog was a red merle Aussie that I had for almost 17 years. Sometimes I see a lot of her in my Collie, even though they are not, of course, related in any way. I was so lucky to have had her in my life. Aussies are great dogs!

I meant "so that we MAY take a look at it". It is time for bed.
If you have an updated picture you could post please do so that we make take a look and see if we can spot it?
I would have the eye checked by your Vet, or by Veterinary Ophthalmologist if needed, to ensure that there is not a problem. There are malignancies like melanomas, that can be responsible for pigmentary changes, but sometimes the pigmentary changes may be benign and nothing to worry about.
Usually, their eyes will change color prior to six months of age.
Better safe than sorry.
Please post back and let us know how you make out.
