Joseph R. McGinniss, Sr. (December 9, 1942 – March 10, 2014), known as Joe McGinniss, was an American non-fiction writer and novelist.

The Journalist and the Murderer is a study by Janet Malcolm about the ethics of journalism, published by Alfred A. Knopf/Random House in 1990.
 It is an examination of the professional choices that shape a work of non-fiction, as well as a rumination on the morality that underpins the journalistic enterprise.
 The journalist in question is Joe McGinniss; the murderer is the former Special Forces captain Dr. Jeffrey R. MacDonald, who became the subject of McGinniss' 1983 book "Fatal Vision".
Emmetropia is the state of vision where a faraway object at infinity is in sharp focus with the eye lens in a neutral or relaxed state.
 This condition of the normal eye is achieved when the refractive power of the cornea and the axial length of the eye balance out, which focuses rays exactly on the retina, resulting in perfect vision.
 A human eye in a state of emmetropia requires no corrective lenses; the vision scores well on a visual acuity test (such as an eye chart test).
 For example, on a Snellen chart test, emmetropic eyes score at "6/6"(m) or "20/20"(ft) vision, whereas myopic (near-sighted) eyes might score at 20/40 and hyperopic (far-sighted) eyes might score at 20/15.
