What is Blur
There are many sources of failure to recognize characters, blur is the only one addressed by EM. Blur is when the edges of the thing you are looking at is not well defined. Print may be too small to see without being blurry. A normal healthy eye can experience blur by looking through a lens not designed for it.
Myopic vs Hyperopic Blur
Myopic blur is the type of blur normally experienced by people with uncorrected myopia. Hyperopic blur is the type normally experienced by people with hyperopia. In order to induce blur, use a lens with the opposite diopter sign as the lens normally used for blur correction, so a plus lens will give myopic blur to an emmetrope.
Studies show that extreme hyperopic blur conditions induce myopia in growing animals, and myopic blur in growing myopic animals can partially reverse this.
