Double vision

Jump to navigation Jump to search

Double Vision, misaligned vision, or ghosting, is when your visual cortex perceives two images when there should be one.

This phenomenon usually occurs as an intermediate step in your vision improvement and is to be differentiated from Astigmatism ("Directional Blur"). Your vision biology is constantly adjusting to environmental stimulus, whereby different parts of your system respond at different rates. After clearing up Ciliary Spasm and after starting to improve the physical shape of your eyeball, your visual cortex already receives plenty of clear data. Our brains however were not built to handle artificial changes to the natural Focal Plane. This means that even when the image hitting your Retina is clear after reducing the strength of your glasses, your brain has to relearn how to create a single clear image out of this new data. This can take longer than resolving the refractive state of your eyeballs and manifests in multiple overlapping clear images of the same image. This might be somewhat common as you start improving your eyesight - more ghosted images will begin to appear as your visual cortex is constantly learning to readjust to new signals.

Double Vision can be more pronounced once you are in the Low Myopia range, since every small change in your diopter strength then results in a larger shift of your Focal Plane.
