Monoculars: Introduction

Monoculars are versatile telescopic devices that provide enlarged images of distant objects. While some people describe a monocular as half of a binocular, the truth is that monoculars have numerous advantages compared to other optical tools. Monoculars are highly compact, lightweight, and portable. Moreover, professionals favor night vision monoculars overnight vision binoculars as having one eye free to examine the surroundings can be invaluable. Note that monoculars are used in a variety of settings, such as hunting, surveillance, birding, reading, and even stargazing.

Interestingly, the history of monoculars is linked to that of other magnifying devices. We should note that the first refractor telescope was invented in the 17th century, with spectacle-maker Hans Lippershey being credited with the invention of the telescope, whereas the first real binocular (as we know them today) was built in the 19th century. One of the main advancements in lens technology that fostered the design of modern monoculars was the employment of prism-erecting systems to correct image orientation, launched in 1854 by Ignazio Porro and Jean Georges Hofmann. Today, such systems are integrated part of monoculars and adopted by some of the best optical brands, such as Vortex, Celestron, Bushnell, Wingspan, Nikon, and Zeiss.

Choosing a Monocular

Although monoculars are often overlooked when searching for a magnifying instrument, the truth is that monoculars are invaluable instruments that can be used in a variety of settings, such as marine observations, surveillance, hiking, hunting, and even stargazing. Nevertheless, due to the wide variety of optical products and competitors on the market, choosing a monocular can be a daunting task, especially for beginners. Before purchasing a unit, prospective buyers should consider three main factors:

  • Requirements
  • Specifications
  • Total costs

Requirements: Before buying a telescopic device, users should decide what they’ll use it for (e.g., stargazing, hunting, etc.) and where they’ll be using it (e.g., hiking expeditions). In fact, the main choice users should make is between binoculars and monoculars. While binoculars are created for use with two eyes, monoculars are suitable for use with one eye, which is highly beneficial for people with vision problems. Furthermore, as stated above, night vision monoculars are highly favored as they do not kill one’s night vision and allow one eye to be free to examine the surroundings. Last but not least, monoculars have only one focus to adjust, which makes them easy and quick to use in different situations.

Specifications: Monoculars magnify images by focusing light through lenses and prisms, with prism systems resulting in light and compact designs. Two of the main specifications to consider are magnification and lens diameter. Interestingly, monoculars for sale come with two parameters (e.g., 6×42): one is the magnification level (e.g., 6X), the other one is the diameter of the lens (e.g., 42 mm). Note that lower magnification provides a bigger field of view.  Usually, telescopes are defined as devices with magnification over 20X and aperture of 60-90 mm. Note that telescopes normally require a stand (e.g., tripod). On the other hand, just like binoculars, popular parameters for monoculars are 7×25, 8×30, 8×42, and 10×42.

Total costs: Given the vast variety of optical products for sale, choosing a powerful but affordable unit can be challenging. Magnification, aperture, and materials used are the three main factors that affect total costs. Usually, monoculars are cheaper than binoculars and easier to maintain. Accessories, such as the wrist or neck-straps, should be considered, especially for hiking, hunting, and any other outdoor adventure. Note that for people with arthritis or similar health problems, a neck strap can be better than a wrist strap in order to improve comfort and user experience.
