The forward-facing eyes of a bird of prey give binocular vision, which is assisted by a double fovea. [4] The raptor's adaptations for optimum visual resolution (an American kestrel can see a 2–mm insect from the top of an 18–m tree) has a disadvantage in that its vision is poor in low light level, and it must roost at night.

Image-stabilized binoculars are binoculars that have a mechanism for decreasing the apparent motion of the view due to binocular movement. [1] Such binoculars are designed to minimize image shaking in hand-held applications. Higher-power binoculars magnify the image more, but the image shift is also increased. This means that even minor hand ...
Directories: Some devices provide directories that guide users to easily target specific attractions within a tower viewer's field of vision.; Focus, magnification, and power: Some devices focus automatically, while others permit users to manually adjust a viewer's focus and magnification to suit their individual needs.
