Kittens Eyes

We recently found this kitten. Someone dumped him at my Sisters job and there is nothing but open fields around with coyotes. She felt bad for him and I ended up taking him home. However he something strange going on with his eyes. He has some brown stops. Its kind of bumpy. Its not flat. Ive been around cats before but Ive never seen this before. Anyone know what it could be? We will be seeing the vet in the next few days but I though I would ask.

You are great for taking him in and caring for him. I have never seen anything like that before and it certainly needs professional attention. Can he actually see OK?

It could be a stye but it could be a number of other things too. I've never seen anything like it. It definitely requires medical attention.

He doesnt seem to have any problems with his vision. At least not that I can see. Acts like a normal little kitty but does have those bump things in both his eyes.
