This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

No, your eyes can't do it on a screen. The effect is physically caused by the different distances of two objects, but the screen is always the same distance from you.
Yes, but you still get the blurry effect outside of the spot on the screen you're focused on.
Not in the same way. Our eyes have lower resolution away from the center, but that's not what's causing DoF effects. You're still missing the actual DoF.
If the effect was only caused by your eye, the depth wouldn't matter, but it clearly does.
Yeah I get it, I'm just saying it's unnecessary. If I need to see what's going on in the background, then my eyes should be able to focus on it.
There are very few scenarios where DoF would be appropriate (like playing a character who lost their glasses).
Like chromatic aberration, which feels appropriate for Cyberpunk, since the main character gets eye implants and fits the cyberpunk theme.
I'm not sure I agree. Just like Motion Blur, DoF is a real phenomenon, and we notice when it's absent. There are lots of good artistic reasons to use it.
But just like Motion Blur, it's really hard and costly to implement properly. Unless you have close-to-perfect eye tracking, it will be annoying because of what you describe. So until we've got that working well, having no DoF is much better.
You don't know what focusing on things is?
