why does vision seem to improve when we simulate binoculars with our hands?

The pinhole effect. Only light rays coming straight (parallel) into your eyes are present. This removes some of the distorted rays.

A lot of our vision happens in our brains. Our eyes are actually terrible cameras, and jump around a lot to compensate for the distortion and the narrow field of view they have. Our brains take all that image information and smooths it into what we think we see.
Putting your hands over your eyes like that cuts out a lot of the edge stuff. Our eyes don’t jump around as much since we recognize that there is nothing worth noticing there, so we are gathering more light from the area on the binocular holes. Additionally, it taxes the vision part of our brain less, so we can focus more on that patch that is directly ahead of us.

I know this pinhole effect, you can do this by putting your first finger and thumb together on one hand, and then put your other index finger onto them so there’s a tiny triangle hole.
Look through that and you’ll see everything is dimmer, but sharper, but I can’t see two big holes like you are pretending you have binoculars having that effect. The smaller the aperture, the larger the focal range is.
One thing that could happen though is you block out more light which allows your pupils to open up more. This is the same thing as having you hand up like a baseball cap visor when looking around. You shield your eyes from the glare from the brighter sky
