A quick footnote to Nathaniel's answer:
If an image looks blurred to you it's because you are viewing it in a plane that isn't the focal plane.
If you put a screen where I've drawn the red dotted line then the image on the screen will look blurred.
If you measure the light in the red dotted plane then at every point in that plane the light wave will have an intensity and a relative phase. If you know the intensity and phase then you can reconstruct the in focus image using the Huygens construction, and indeed the process is known as Huygen's deconvolution. The trouble is that when you take a photograph the photographic process only records the light intensity and it loses the phase.
So if you're starting from a photograph you've lost half the information originally present, i.e. the relative phase, and that means it's impossible to reconstruct a perfectly focussed image. A blurred photograph won't look normal to anyone - myopic or otherwise. However it is usually possible to improve the blurred picture to some extent, which is why Huygens deconvolution software is so widely available.
