I think the eye measures the length of the object in relation to the degree of divergence in the viewing angle, which is the angle
They are located extending from the center of the eye to both ends of the visible object. If this
The thing is very far away, the angle of view is sharp to the extreme degree, so imagine the eye
The two ends of the thing meet at one point.
Because the eye measures the length of the object by the degree of diffraction of the viewing angle, which is the angle whose ribs extend from the center of the eye to the ends of the visible object. If this thing is too far, the angle of view is acute to the extreme, so the eye visualizes that the two ends of the object meet at one point.

Dear Dr- Huda Shihab jari , keep in mind that your eyes perceive a fixed field of view. That is, you see a certain angle in front of you. They do not see a fixed distance across your line of sight. This means that the farther away for you you look, the more distance there is from one side of your FOV to the other. When you look at parallel railroad tracks that maintain a certain distance apart, they seem to converge as they go off into the distance. This is because the proportion of your field of view that the tracks take up diminishes.

I feel the range of our eyes to see something is infinite. There is a difference between looking at the sky and viewing a parallel line. Great question. Following the answers.
It's an optical trick. We don't see with the eyes but with the brain.Why?
If you try to see what's inside a tunnel at one point you will see nothing much than darkness if the tunnel did not change direction. But if it changes direction you would see the intersection.
Similarly if you see a railway track converge at a distance it has probably taken a turn. Or an optical illusion had occurred because you are also seeing things at the background in which the railway track is located.
