Monoculars

Monocular

— monoculars are actually short telescopes. They have one optical system, unlike binoculars, which determined all the advantages and disadvantages of this type. On the one hand, such devices are more convenient to carry, because. weigh less and take up less space; they can also be used if the visual impairment does not allow the observer to see normally with both eyes at once. On the other hand, when looking through a monocular, there is no volume effect, and the need to constantly squint one eye leads to rapid fatigue.
