Context

Country: Canada
State/Province: Unknown
Period: Possibly early 20th century
Canada: May have been used in Northern Canada.
Function: Viewing details on distant objects.
Technical: Unlike a (monocular) telescope, binoculars give users a three-dimensional image: for nearer objects the two views, presented to each of the viewer's eyes from slightly different viewpoints, produce a merged view with an impression of depth. There is no need to close or obstruct one eye to avoid confusion, as is common with monocular telescopes. The use of both eyes also significantly increases the perceived visual acuity (resolution), even at greater distances where depth perception is not apparent.
Area Notes: Unknown
