While specialized applications still consider the telescope very useful, single lens optics have been replaced by binocular optical systems in most other cases. Students and scientists, sailors and soldiers, just to mention a few, enjoy the benefits of binocular vision. Improved detail and viewing area, as well as reduced eye strain are a few of the benefits binoculars provide over monocular devices.
Binoculars utilize two single lens optic systems to provide a number of improvements to the viewed image. By using both eyes, stereopsis, which is a perceived sense of depth and dimension, is created as each eye combines slightly different images.
This sense of depth is something previously unavailable with monoculars, which used just one eye. By using binocular vision, each eye receives its own image, resulting in increased detection of movement and minute details. This effectively doubles the usefulness for the user.
Binocular vision provides substantial advantages. An example would be to keep one eye closed while you went about your day. Your field of vision would be reduced and half of your normal viewing perception would be gone. Normal reaction times would decrease. The distance of objects, normally easy to determine, would become difficult to perceive, again slowing your actions.
These difficulties are only a few faced by observers before the advent of binoculars. Since their invention, technology and optical components have progressed, providing the user with an improved viewing experience.
