The change to the size and shape of the eyeball, in response to [[hyperopic defocus]], happens relatively quickly. The [[double vision]] is a lag-period where the [[visual cortex]] is learning to interpret the changed signal it is receiving; it is learning to "align" the images.

Because the changes to the eye and the brain don't occur at the same pace progression of visual perception is generally experienced as:
