This is a special type of Aussie most don't come split. Split meaning a variation of pigment coloring in the eyes and color. The right half is brown and it has a solid brown eye, the left side has a geometric split eye of white and brown. No known breeding tests have been performed to date to determine the heritability or lack of heritability of this trait.
They could also have something called "eye shine" where at the back of the eye is a layer of reflective pigment called the choroid area. The mirror like layer allows the dogs to see very well even in dim light. (Summer has this. Her eye sight is amazing, she could see a crumb from across the room) Eyes lacking in the pigment give the illusion of being red.
Solid Eye colors and Odd Eyes: Green eyes are most often seen in red and red merles
The presence of this pigment pattern in a nonmerle suggests that some other factor is involved in producing it. Aussie eyes can be any color, and this is within the normal range of variation. It is a very unusual and fascinating variation that is very eye catching when it occurs. (Summer sometimes has this happen, her eyes are so striking)
