The blind-spot answer is good, but it also happens when there is no particular reason for what you're looking for to be close by. When we look for something, it's natural to look at all the places it's most likely to be first if those places can be searched quickly. If something can be anywhere in the a field, for example, that means scanning your eyes around the field as a whole. If chance has it that it happened to be right underfoot, our eyes are pointed to high up to see it.

The human eye has a blind spot in its field of vision. This lies on the point of the retina where the optic nerve leads back into the brain. The retina has no light-sensitive rods or cones at this point, and so a small object in the field of vision's blind spot becomes invisible.

Sometimes the very thing were looking for is the one thing we cant see, or sometimes it's because if in a hurry we tend to overlook the very thing that is right infront of us.

blind spot...a small spot where the retina is unattached to the eye so we can not see...happens in driving too...but sometimes, your own nose might be obstructing your vision :-P
