Why do cats get cloudy eyes and don't respond to affection?

When it comes to cat health, eyes have long been of particular interest to me. Cats can develop cat eye problems not just from a direct problem with their eyes such as cat glaucoma or cat herpes, but also secondary to systemic cat diseases such as feline immunodeficiency virus or cat leukemia. I'm sure many of you have experienced a lasting interest in a condition when a cat you love has had a problem with it. That's what happened to me.
