May need to clarify: I am not exactly sure what you mean by this question, so you might to clarify it. You might be referring to the observation that if you observe something and are looking very close to an edge, like the edge of glasses in an extreme gaze position, or by squinting, you get a "pinhole effect". Basically, some light rays don'pt need to focused, and appear to become clear. This is an optical phenomenon.
