glass eye / blue eye
 
2 Attachment(s)
I was asked about one of our foals if it has glass eyes or blue eyes. Now, I have two questions:
1. I always thought glass eye = blue eye - or is there a difference?
2. As you can see in the picture this filly has only partial blue eyes - in both eyes the lower half is blue, the upper half is brown. She is pure bred Quarter Horse, non of her siblings / close family shows any signs of an overo pattern. Her dam is home bred with many half and full siblings, her sire has two foal crops and none was noticably colored. Any idea what causes the partial blue eyes?

What is a 'glass eye'. I'm assuming its not like the horse has an actual 'glass' eye so is it a term for something?

Glass, moon, China, wall, night...they're all just blue eyes.

As I said in a previous thread, face white is still the result of a white patterning gene, and this is probably what is causing the blue eyes.

Glass eye is usually the term for a light colored eye. I have to admit that I am somewhat confused myself after I was asked by a presumably knowledgeable horse person if the horse has a glass eye OR a blue eye :shock:
Maybe I am missing something - however, it usually does not mean an eye made of glass, literally :-)

And I would have to agree, however, I have never seen a solid horse with two partial blue eyes. One partial or one or two full blue, but two partial and no other signs of a pattern in her family (she comes from an old and established breeding program) - this is weird!

This horse has no white on him at all, and has blue eyes. Both eyes are completely blue. He has been DNA tested and verified as having frame.

cool pic! Any ideas about partial blue eyes? I guess it's just like an "unfinished marking" - or Splash and Frame fighting for domination? ;-)

My black horse has a blue eye. She has no white around it. Just a star and a snip.
