Pseudomyopia occurs when a spasm of the ciliary muscle prevents the eye from focusing in the distance, sometimes intermittently; this is different from myopia which is caused by the eye's shape or other basic anatomy. Pseudomyopia may be either organic, through stimulation of the parasympathetic nervous system, or functional in origin, through eye strain or fatigue of ocular systems. It is common in young adults who have active accommodation, and classically occurs after a change in visual requirements, such as students preparing for an exam, or a change in occupation.

- La pseudomiopia è una temporanea e anomala condizione rifrattiva dell'occhio, assimilabile per sintomi e caratteristiche ad una miopia, ovvero un eccesso di potenza che porta il sistema ottico a focalizzare le immagini in un range di spazio che precede la retina, non riuscendo così a garantire una visione nitida per oggetti distanti. Tale condizione è dovuta ad uno spasmo del muscolo ciliare, la cui funzione è di accomodare, ovvero modificare la geometria del cristallino e conseguentemente il potere dello stesso. (it)
- 假性近视是指眼睛類似近視的暫時性變化，是因睫状肌的暫時性痉挛，造成眼睛的折光力增加，成像在視網膜前方的情形。假性近视可能是是因為是副交感神经受激而產生，也可能是因為眼睛或視覺系统疲劳而產生。在良好的年輕人中，假性近视是常見的情形，常出現在需要長時間看東西或閱讀的情形，例如學生準備考試，或是工作的變化。 假性近视的主要症狀是會間隔性的對較遠的東西看不清楚，特別是在長時間近距離工作後更容易出現，也會有眼睛疲勞的症狀。佩戴近视眼鏡後會暫時看的較清楚。其診斷可以用的方式進行，在眼睛中滴入像阿托品或是之類的。調整閱讀或視物的姿勢也可以減少睫狀肌痙攣的情形。 假性近视的治療和其底層的病因有關。器官性的原因可能包括全身藥物或眼部藥物的影響、腦幹損傷、或是眼部的發炎（例如葡萄膜炎）。功能性的假性近视可以由調整工作環境、調整眼部折射情形，或是進行適當的眼部運動來改善。 (zh)
