objects get smaller because as they travel away from you the rays of light reflected off them and into your eye become closer and closer to being parallel with each other and forming a 90 degree angle with the front of your eye, we gouge size by the angle at which the light rays enter are eye, the closer they get to being at 90 degrees to the eye the smaller they appear. We have this ability so that when we were hunter gatherers we could tell how far away prey was.

It's called field of vision ! as the eye does not view in a parallel line ,but expands in width increasing the field of vision the objects appear smaller as you see more! Thus using a telescope/binoculars etc the field is kept more parallel thus keeping the object large.

Objects don't get smaller, they just appear smaller. Its because they take up less of our field of vision. Our brain just perceives them as smaller.

Perspective is very handy for judging distance.
If there was no perspective, imagine what the night sky would look like filled with all those full-sized stars.

Things don't actually get smaller as they get farther away, they just look like that.

So we don't run into everything in front of us, thinking it's miles away - it's an adaptation; we wouldn't have survived long without it.
