Before you consider looking for a monocular, consider gaining knowledge about it. A monocular would be a low-powered, small telescope you could hold in your hand similar to binoculars. However, you would be using one eye to see through a monocular and view the objects at a distance while hunting, watching a sporting event, or camping. 

A monocular could also be used as a magnifier for reading hard-to-read texts. You could choose the best night vision monoculars by looking at the magnification power of the size and weight of the device. Consider shopping for a few available options to find the one offering a high-quality product at an affordable price. 

Find below a few essential aspects to consider for choosing the best monocular. 

1. Decide the magnification you require 
The magnification power would affect the distance you want to view along with the detail you want to see. These high magnification devices would provide you with a further and detailed view. A majority of monoculars would offer a magnification power ranging from 5x to 8x. 

It would be in your best interest to remember that a higher magnification power would result in a lower field of view. Therefore, consider buying a monocular from with lower magnification power for a wide field of view. 

2. Determining the size of the lens 
It would be in your best interest to consider the perfect size of the lens. A bigger lend would enable you to see a wider view and seek a brighter and better image. A smaller lens might not offer a good view. However, they would be relatively easier to use and relatively less bulky. Most monoculars would offer a lens size ranging from 20mm to 42mm. 

3. Check for coating on the lens 
Most monoculars would come equipped with an anti-glare coating on the lens. It could affect the brightness of the image along with obscuring or enhancing your view through the monocular. The range of anti-glare coverage would range from external elements to all fully coated lenses. An expensive yet best option would be to look for a completely multi-coated lens. It implies that all sides of the lenses offer several layers of anti-glare coatings. It would not provide you with an obscured view. 

4. Considering the prism 
Rest assured that both the lenses along with the prisms would refract the light. It would enable you to view magnified distant images. Monoculars would make the most of roof prism, also known as Porro prism. The type of prism used would be dependent on the magnification level of the monocular. 

In the event, you were choosing a model with a relatively higher magnification; the monocular would most likely come equipped with a roof prism. The image produced would be relatively compact and narrow than what the Porro prism produces. 

5. Testing the monoculars close focus 
Consider checking the close focus competencies on the monocular. Rest assured that the close focus would be the focus of the monocular on the object at a specific distance. Close focus is measured in inches instead of yards.
