Lens blur is a fullscreen effect intended to replicate the visual acuity of a camera in the virtual environment. It is also known as depth blur, depth of field, or focus blur. It creates a focus-field, usually by means very similar to an alpha blend of the final image in the video buffer, which renders only objects at a given depth as solid. The others get rendered increasingly fuzzily as they move away from the target depth.

?There lacks in the gaming community any sort of lens through which to help better view or understand the development of a game player.
