With the use of lenses and prisms a monocular facilitates the user to view things which are located far away as if they are very near. I've blogged about them, reviewed them for the site I purchased them off, and happily recommended them to friends and colleagues.
To correct this, two prisms are placed inside the binoculars, between the objective and the eyepiece. Most pocket binoculars have multi-coated lenses and high-refraction prisms. If you are going to use the binoculars yourself go for a higher quality optics which naturally would cost more.
Such lens cloths take even fingerprints and stains of all sorts off your binocular lens. In order to define the quality performance of their products, binocular makers present the field of view in mathematical conversions that show a variance of fields. Most compact binoculars provide a wide field view and bright images.
Others have comfortable straps so you can wear them around your neck. You want to keep these for years to come so you might as well be comfortable.
