Empty Field Myopia

Empty Field Myopia

Definition

Empty field myopia (Empty space myopia) - a condition in which the eyes, having nothing specific within the available visual field upon which to focus, focus automatically at a range of the order of a few metres ahead. Detection of objects outside this restricted field of view is delayed and if an object of interest does enter the restricted field of vision, the determination of its size or range would be problematic.

Description

The normal function of the eye lens is to physically focus light from the object on the retina. To do this, the eye must be stimulated by an image. Empty field myopia manifests itself when the human eye is in a passive state of focal point adjustment, i.e. when there is no image (stimulus) for the eye to focus on, for example, when the eye is either in complete darkness, or looking at a bright empty field. If the eye lacks this stimulation, the lens is shifting to a resting state.
