I don't know if what I feel reflects your experience, but I often feel like I am not "a part" of the world I'm in. I wouldn't describe it was a problem with my eyes, or a feeling as though looking through a plastic bottle. It feels more like I am a spectator, and everything feels at once distant and familiar. I constantly feel like I can't get over how things became the way they are. Everything feels novel and strange; fascinating and dreamlike. Surreal, yes, like I'm in a simulation or some transient state. But contrary to what you describe, I actually feel a
deeper sense of clarity when I'm like this.
But like I said, it doesn't feel like a problem with my eyes. It feels more like a persistent mind state. And I wouldn't say it's something that I struggle with or distresses me. In fact I like it. It feels like I never lost my sense of childlike wonder and curiosity. I wish I could wander around like this endlessly, but my real world obligations tie me down.

I probably meant "Like looking through the bottom of a coke bottle" you know the glass ones. Does that help? I remember reading this somewhere I but I was trying to adapt it to my situation so I said plastic bottle. Both are valid in indirectly describing my perception.
