Translation by Henry Thomas Colebrooke (1837): From various causes things may be imperceptible (or unperceived); excessive distance, (extreme) nearness, defect of the organs, inattention, minuteness, interposition of objects, predominance of other matters, and intermixture with the like.

Translation by John Davies (1881): (This want of perception may be) from excessive distance, too great nearness, destruction of organs, inattention of the mind (manas), minuteness, concealment (by other objects), predominance (of other things), and by intermixture with like objects.

Translation by Ganganath Jha (1896): (Non-perception arises) from excessive distance, extreme proximity, destruction of the sense-organs, absence of mind (inattention), subtlety (or minuteness), intervention (or the existence of some intermediate barrier), predominance (of other objects), and from intermixture with other like objects.

Translation by Nandalal Sinha (1915): (Apprehension of even existing things may not take place) through extreme remoteness, nearness, impairment of the senses, non-presence of the mind, extreme fineness, intervention, suppression by other matters, intermixture with likes, and other causes.

Translation by Har Dutt Sharma (1933): On account of excessive distance, (excessive) proximity, injury to senses, inattention, minuteness, obstruction, suppression and mixture with what is similar, (even the existent objects are not perceived).

Translation by Radhanath Phukan (1960): Non-perception of a thing which really exists may arise from the following causes: (1) extreme distance; (2) extreme proximity to the eye; (3) injury to the sense-organs; (4) want of attention of the mind; (5) extreme subtlety of the object, e.g., an atom; (6) the object to be observed being veiled or suppressed; (7) the object being mixed up with similar things.

Translation by Swami Virupakshananda (1995): (Apprehension of even existing things does not arise) through excessive distance, proximity, impairment of senses, absentmindedness, subtlety, intervention, suppression by other objects, intermixture with other similar objects, and other causes.

Translation by G. Srinivasan (recent): Extremely far or near distances, mental and sensory inefficiencies, subtle or attenuated conditions, occultation or eclipsing of the object, poor background contrast, camouflaging effect (are the causes of non detection or non measurement of phenomenon).
