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

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
