Why do objects that are farther away appear smaller. The moon for example looks small from earth, but I don't understand why.

You wouldn't see any objects at all.johnEHDS said:So if we had flat eyes and not lenses, then objects would appear to be the same size no matter ho far a way they were? Surely this is possible to emulate with a CCD that had no lens to concentrate the light ?
You'd need telecentric lens for it: http://www.lhup.edu/~dsimanek/3d/telecent.htmjohnEHDS said:So if we had flat eyes and not lenses, then objects would appear to be the same size no matter ho far a way they were?

A bare sensor with no lens doesn't focus light to create an image.johnEHDS said:So if we had flat eyes and not lenses, then objects would appear to be the same size no matter ho far a way they were?

Objects appear smaller when they are farther away because of the way light travels. Light rays from the object spread out as they travel, making the object's image on our retina smaller.
Yes, perspective is a key factor in why objects appear smaller as they get farther away. The farther an object is, the smaller the angle between our line of sight and the object becomes, resulting in a smaller perceived size.
Our brain uses visual cues, such as depth perception and comparison with nearby objects, to interpret the size of distant objects. This is why objects next to a distant object may appear larger in comparison, even though they are actually the same size.
Yes, the concept of objects appearing smaller as they get farther away also applies to other senses. For example, sounds become quieter and less distinct as they travel farther away from their source.
Yes, there is a limit to how small an object can appear due to distance. This is because there is a minimum size at which our eyes can perceive an object, and as the object gets smaller, it may become too small for us to see it with our naked eye.
