Monoculars are a modified refracting telescope used to magnify the images of distant objects by passing light through a series of lenses and usually prisms, they can be purchased at justopticsandscopes.com. The application of prisms results in a lightweight, compact telescope. Volume and weight are less than half those of binoculars of similar optical properties, making it easy to carry, and also proportionally less expensive. Monoculars produce 2-dimensional images, while binoculars add perception of depth (3 dimensions), assuming one has normal binocular vision. Check out our selection of monoculars at justopticsandscopes.com.
Monoculars are ideally suited to those with vision in only one eye, or where compactness and low weight are important (e.g. hiking). However, monoculars are sometimes preferred where difficulties occur using both eyes through binoculars because of significant eye variation or poor vision in one eye, see our selection at justopticsandscopes.com
A monocular with a straight optical path is relatively long; prisms are normally used to fold the optical path to make an instrument which is much shorter (see the entry on binoculars for details). Come see us at justopticsandscopes.com for your selection of monoculars.
