Binoculars are versatile tools that provide enlarged images of distant objects. Note that binoculars are made of two telescopes mounted on a single frame, which allows the use of both eyes.
The design of binoculars has evolved significantly over the centuries. Although the phenomenon of magnification was highly valued in the ancient world, the first reflector telescope was invented in the 17th century, with spectacle-maker Hans Lippershey being credited as the inventor of the telescope and Galileo Galilei as the scientist who pointed the telescope towards the skies. Interestingly, the first binoculars consisted of pairs of Galilean telescopes, followed by box-shaped models for terrestrial use (produced by notable scientists such as Dobler, Cherubin dÓrleans, and Pietro Patroni). The first real binocular was built in 1825 by J.P. Lemiere. In 1854, Ignazio Porro introduced the use of prism-erecting systems to correct image orientation, which was launched by Porro and Hofmann in 1860. Binoculars were further improved by Ernst Abbe and Carls Zeiss, and the first modern pair of binoculars was sold in 1894.
Now, some of the major brands that offer high-quality telescopic products (including camouflage models, spotting scopes, and night-vision devices) are Bushnell, Celestron, Vortex, Carson, Nikon, Zeiss, and Eyeskey.
Choosing a Binocular: Factors to Consider
Binoculars are fascinating instruments, highly popular in a variety of settings, such as hiking, wildlife viewing, birding, hunting, boating, stargazing, sports, and theatre. However, given the wide number of telescopic products available on the market, choosing a model can be a challenging task. The main factors to consider before purchasing a pair of binoculars are:
- Total costs
Requirements: Before purchasing binoculars, users should refine their goals and requirements. As there are different models suitable for different purposes, buyers should decide what they’ll use their unit for (e.g., birding, hiking, hunting, ship spotting) and where they’ll be using it (e.g., low-light conditions). If a new pair of binoculars will be used outdoors, factors such as weather conditions and light should be considered. Note that low-light performance is usually increased by using bigger objectives and an exit pupil of over five mm. That being said, the size of the unit also matters. There are three types of objective lens sizes: full-size (ideal for hunting and wildlife viewing), mid-size (used for hiking and sports), and compact (perfect for daytime activities and young learners).
Here we should note that for people who wear eyeglasses and sunglasses, the eye relief distance is another vital characteristic to consider. The longer the eye relief is, the better (e.g., of at least 10 mm). Extendable eyepieces can further improve user experience.
Specifications: Magnification and lens diameter are the two main specifications to consider when purchasing a binocular unit. Usually, binoculars have two indications (e.g., 7×50); one is the magnification level (e.g., 7X), the other one is the diameter of the lens (e.g., 50 mm). Note that a bigger diameter translates into more light-gathering. Certain magnification rates, on the other hand, suit certain activities: lower magnification provides a bigger field of view and helps users hold a steady image, while higher magnification is ideal for activities like stargazing. That being said, recent advancements in lens technology provide image stabilization to correct the blurs caused by high magnification and hand movements. The most common magnification rates are 5X, 7X, 8X, 10X, and 12X.
The type of focusing system also matters, especially for beginners. There are two types of focusing systems: central focusing (units that are equipped with a central knob that controls the two tubes simultaneously) and individual focusing (models with two diopter adjustment rings for each eyepiece).
Total costs: Deciding on a budget is paramount. Usually, high-quality products and those designed for stargazing and long-distance use (e.g., train, plane, and ship spotting) can be costly. The material used can also affect prices, with plastic lenses being cheaper than glass lenses. We should mention, however, there are pricey plastic lenses offering high optical and impact-resistant performance. Coatings are another factor that can impact the total cost of a unit, with fully multi-coated binoculars being pricier than other models.
Last but not least, buyers should consider buying accessories for their binoculars. Bags and straps made of sturdy materials are essential to protect binoculars from harsh weather and accidental drops. Waterproof and dustproof units and equipment are required for activities, such as hiking, ship spotting, and hunting. Some binoculars, such as those units with high magnification rates, might require additional support (e.g., tripod, monopod) to help reduce the effects of hand tremor and fatigue.

Taking Care of Binoculars
Binoculars are complex systems that can be used in a wide range of settings, such as hiking, patrolling, hunting, stargazing, bird-watching, and theater. Yet, such systems require adequate maintenance. Some of the main steps to ensure accurate use and long lifetime are:
- Adjusting binoculars: Binoculars should be adjusted according to an individual’s needs. Therefore, diopter adjustment and focusing are vital. As explained above, there are two types of focusing systems: central and individual focusing.
- Handling binoculars: Binoculars should be held firmly to ensure sharp and clear images. Neck-straps can be used to prevent accidental drops, while tripods can be used to support heavy units with high magnification.
- Cleaning binoculars: Cleaning telescopic devices and their optical elements are crucial. Use a special cloth, wipes, compressed air, or solution to clean your pair of binoculars and extend its lifetime.
- Storing binoculars: Units should be stored accordingly to reduce any possible adverse effects caused by moisture, sunlight, and excessive heat. Carry bags, for example, are a must-have accessory.
Binoculars are versatile tools that provide enlarged images of distant objects, used in a variety of settings, such as hiking, wildlife viewing, birding, hunting, stargazing, golf, sports events, and theater. Note that binoculars are made of two telescopes mounted on a single frame that allow the use of both eyes. While binoculars have undergone drastic transformations over the centuries, today’s binoculars come in different shapes and sizes, with Bushnell, Celestron, Orion, and Eyeskey being among the most reputable brands on the market.
Prospective buyers should consider three main factors: requirements, specifications, and total costs. Note that different fields of application require different units. To provide an example, astronomy models should have high magnification and lens diameter, while hunting models should be durable and waterproof to resist harsh weather and changing environments. That being said, taking care of a unit is also essential to guarantee long use. Maintaining, cleaning, and storing binoculars accordingly can only prolong a unit’s lifetime; thus, carry bags, neck-straps, and cleaning cloths become must-have accessories.
