For example take a tree. How can our brains tell that it is a big tree far away instead of a smaller tree which is just closer to us?
In: Biology
Your brain measures the slight difference in angle between your eyes looking at the same object. As the distance gets farther, the difference becomes smaller and your judgment of distance becomes less accurate. Context and memory also help.
Before I got glasses as a kid, I used to gauge distance by degree of fuzziness, too. Your brain is more clever than you are.
