when objects are very far off, certainly light has to travel a long distance to reach us. the light emitted by the particle has to travel through many media, which may be denser or rarer and undergoes deviations as a result, very little amount of light reaches our eye, which has undergone least deviation thus objects appear small..

They look smaller because our eyes are made in such a way that they allow us to see things in perspective, so that we can tell roughly how far away things are. If there was a huge monster three miles away, it wouldn't be very helpful to be staring at its feet. So that we can see the maximum capacity of our eyesight, objects must look smaller or everything would look like a massive mess!

I think the real answer is more because that's the way your brain presents a picture of the world to you, based on the information it gets from photons hitting your retina.

Evolution has made sure that what you think you're seeing is a pretty good approximation to what the real world is like, or at least gives you a good chance to avoid danger, get food and a mate, which is all you really need.

Your eyes are not like windows, your image of the world is generated entirely within your brain, and of course your brain can play tricks on you, which is why some people think they 'see' ghosts and other hallucinations, which have really only been added in the processing.

Our eyes determine size by the angle subtended by the image of the object at the eye. If you had only one eye, then a 3 foot child 10 feet away would appear to be the same size as a 6 foot adult 20 feet away, as they both subtend an angle of about 17 degrees at your eye. Because you have two eyes (I assume . . .) you are able to tell distance and your brain then does the calculation based on angle and distance.

The 3 foot child 100 feet away would subtend an angle of only 1.7 degrees, a tenth of the original, therefore appearing to be one tenth the size as described in the first situation.

It is called 'perspective'.
