A point source in the visual field will create a point image on the retina. The "sensor area" you're referring is what's necessary to capture the entire visual field simultaneously.

I disagree that it’s a point source at distances of peak concern.

Also, it’s something of a nitpick but physically point sources still end up as a circle.

That's fair, strictly speaking, but I'm not sure there's a meaningful difference to be made.

Wasn't sure what level of knowledge you were coming from re: PSFs, so I was keeping it basic.
