Black spots on eye?!

I was riding a horse from a rental place, mind you, I had never been here before and do not know how knowledgeable or trustworthy this barn is, and I noticed something on its eye. Apart from the iris, on the white part of both eyes, were blotchy black spots all over. I was curious to know what are these? Are they harmless, do they mean anything? And is there a disease/cure? Thanks!

Extra info: The horse was mostly healthy looking, although it did look slightly underfed.


Thanks again,
Maddie

Without a photo, it's difficult to say for sure, but I have seen many eyes that have what I call "speckles". Just a colour usually.

Yep, a photo would be most helpful. It could be normal or not, but really without seeing it it's impossible to say for sure.

Ok, well I never got a chance to take a picture, but I will try to fine something online just like I.

The white part of the eye is called the Sclera. You don't normally see much of this on a horse unless it is an Appaloosa or has a large blaze(a horse that has the white of the eye showing frequently are usually considered to be spooky) FYI Horses can sometimes have a black sclera. If the spots are greyish/blue it can also be something called Scleral melanocytosis, which is not harmful.
