Wikipedia
emmetropic
Emmetropia is the state of vision in which a faraway object at infinity is in sharp focus with the ciliary muscle in a relaxed state. That condition of the normal eye is achieved when the refractive power of the cornea and eye lens and the axial length of the eye balance out, which focuses rays exactly on the retina, resulting in perfectly sharp distance vision. A human eye in a state of emmetropia requires no corrective lenses for distance; the vision scores well on a visual acuity test (such as an eye chart test). While emmetropia implies an absence of myopia, hyperopia, and other optical aberrations such as astigmatism, a less strict definition requires the spherical equivalent to be between -0.5 and +0.5 D and low enough aberrations such that 20/20 vision is achieved without correction. For example, on a Snellen chart test, emmetropic eyes score at least "6/6"(m) or "20/20"(ft) vision, meaning that at a distance of 20 ft (the first number) they see as well as a "normal" eye at a distance of 20 ft (the second number). Eyes that have enough myopia (near-sighted), hyperopia (far-sighted, excluding latent and facultative hyperopia), or optical aberrations would score worse, e.g. 20/40 (visual acuity of 0.5). Typical emmetropic vision might be 20/15 to 20/10 (visual acuity of 1.3 to 2).Emmetropes with presbyopia might use lenses for near vision.

emmetropic
Emmetropic refers to the state of the eye when it has normal vision, with light rays from distant objects being focused directly on the retina without the need for correction (e.g., glasses or contact lenses). It means the eye is free from major defects such as nearsightedness, farsightedness, or astigmatism.
