Basic Information about Binoculars
What are binoculars?
Binoculars are a parallel combination of two telescopes for viewing an erect image with both eyes. Because they are designed so that an image of the same size can be viewed with both eyes, users can observe objects more comfortably than with a single eye. Also, the perspective and three-dimensional effect of binoculars make viewing more enjoyable.
