    When the sight is perfect, and still more when it is presbyopic, the pupil will have frequent occasion to contract, in aiding the person to see near objects more distinctly, and thus an habitual degree of myopsis may be produced.

Origin

  1. Ancient Greekμυῖα“fly”
  2. Englishmyopsis

From Ancient Greek μυῖα (muîa, “fly”) + ὄψις (ópsis, “sight”). Although myopia is superficially very similar in both the English and original Greek forms, the first parts of the two compounds aren't related.
