Errors and Expectations devotes a chapter to eight of the (at the time) most salient considerations in basic writing. Each chapter follows a three-pronged format: first, a range of examples; second, an explanation of causes of the problems; and third, suggestions with which to approach the problems.
Astigmatism causes difficulties in seeing fine detail. Astigmatism can be often corrected by glasses with a lens that has different radii of curvature in different planes (a cylindrical lens), contact lenses, or refractive surgery. [5] Astigmatism is quite common. Studies have shown that about one in three people suffers from it.
Avoid using jargon. Assume that new users will read the essay, and not just experienced ones. Essays are regularly quoted on article talk pages, and it's possible for a newcomer to stumble on one. Avoid using shortcuts within an essay. Instead, write out the full name of the policy or guideline. Examples:
Astigmatism, although not presumed connected to these visual disturbances, is a common comorbidity. Migraines and tinnitus are common comorbidities that are both associated with a more severe presentation of the syndrome. [13] The cause of the syndrome is unclear. [3]
For example, in the case of myopia, the correction is to reduce the power of the eye's refraction by a so-called minus lens. Neural factors that limit acuity are located in the retina, in the pathways to the brain, or in the brain. Examples of conditions affecting the retina include detached retina and macular degeneration.
This allows a larger useful field of view, and the remaining astigmatism is symmetrical around the distorted objects, allowing astrometry across the wide field of view. However, the astigmatism can be reduced by including a third curved optical element. When this element is a mirror, the result is a three-mirror anastigmat.

An article suffering from such language should be rewritten to correct the problem or, if an editor is unsure how best to make a correction, the article may be tagged with an appropriate template, such as {{Peacock term}}. Puffery is an example of positively loaded language; negatively loaded language should be avoided just as much. People ...
