Monocular (/mɒˈnɒkjʊlər/; from Latin mono meaning "one", and ocular meaning "eye") is a type of optical device that magnifies objects using only one eye. It is a single-eye piece of optical instrument that aids in viewing distant objects.
Etymology
The term "monocular" comes from the Latin words mono meaning "one" and ocular meaning "eye". It was first used in the early 17th century to describe a single-eye piece of optical instrument.
Usage
Monoculars are often used in various fields such as birdwatching, hunting, and astronomy. They are also used in the military for reconnaissance and surveillance. Monoculars are preferred over binoculars in situations where weight and size are important factors, as they are generally smaller and lighter.
