These are one of two parts of eyes. But, there are some situations, which we can not see even a large object. As an example, can you see an elephant as it is when you are one foot away from it? Thus, we have to discuss the distance which a human eye can see through two different ways. First is the nearest distance and next max value.

Next two factors influence on how far can a human eye see...

The Roundness of the World
