Has anyone ever seen these type of eyes on a chicken or is this just some kind of mutation?

I suspect ocular Marek's as well.

but she’s been with the flock for 3 years and none of them have caught it, all they’re eyes look normal except hers i feel like it’s a genetic mutation, i might be in denial because i’m scared but i’m not sure

There's no genetic mutation that looks quite like that. No need to be scared, you just need to tighten bio security

I hope that I am wrong about it being Mareks. There is testing that can be done at home on living chickens, by collecting a blood sample with materials sent to you by RAL, a national lab, and then you send it back to them. However, I would just see how your hen gets along, and if you ever lose her, have your state vet perform a necropsy and testing. That is the best way to diagnose it. Here is link for RAL to ask about testing if you want to do it:
