From the Paper:

"Human beings may have any of a number of visual problems which can be corrected by wearing lenses, either glasses or contact lenses. The basic problems so addressed are known as far-sightedness, short-sightedness, and astigmatism, all based on the way the eye reacts to light and the physical shape of the eye. Visual problems are discovered in an eye examination, and the three types noted above can all be revealed in such an examination. Myopia is the most common of the three issues. Hyperopia, or far-sightedness, occurs when the shape of the eye leaves too little room for focusing so that the image focuses beyond the retina."
