Mounted on a Tripod

To get more stable observations, attach the tripod to the threaded attachment at the bottom of the monocle.

Attached to a Smartphone Holder

The smartphone holder included with the kit is compatible with most phones on the market so you can easily connect them to the monocular in just five easy step.

Step 4: To connect the eyepiece of a monocular to a smartphone, move the eyepiece back and forth until the desired position is reached. Then, hold the eyepiece steady and press the shutter button on the smartphone.

Step 5: Open your camera app and take a picture of the screen. Then, use an editing tool to crop out the black edges and adjust the focus ring so that you get a clear view.

Cleaning and Caring for Monocular Lens

Monoculars don’t need any special care, but they must be protected from dust and moisture when not in use. They cannot be fixed or changed, so you need to take extra precautions.


The monocular has two lenses

  • the ocular lens
  • the objective lens

You don’t need to keep your lenses clean after every single time you wear them; however, frequent cleaning can cause scratches and damage the external coat­ing.

Microfiber Cloth

Use a microfibre cleaning towel and gently wipe in a circle motion. Do not rub the lens. If you need to clean something off the lens, use an eyeglass cleaner designed for lenses.

Glasses Cloth

You can also use the eyeglass cleaning cloth instead of the microfiber cloth if you prefer. It’s ideal for delicate eyeshades.

Photographic Type Detergent

To clean your camera lenses properly, follow these steps:

  • Clean the outside of the camera using a soft brush;
  • Remove any dust from the inside of the camera by gently blowing out the interior;
  • Rinse the camera thoroughly under running water;
  • Dry the camera completely before storing it.

Even if it is waterproof, don’t submerge the monocular in any kind of liquid because this could cause condensation inside.

Protect Your Monoculars from Dropping and Breaking

Lens Cover

You must use the protective case provided by the manufacturer when using these external contact lense.

To keep out moisture, debris, and humidity, we’ve designed our monoculars to be sealed shut when they’re not in use.

Wrist Strap

The handgrip ensures a firm hold even when moving and during outdoor activities to prevent falling and damage to the monoculars.

Protective Case

Keep the monocular in its case when not in use. Store it in a cool and dry location, away from direct sunlight, and avoid rough handling.

Frequently Asked Questions (FAQs)

What are monoculars good for?

Binoculars provide a wider-angle viewing experience than monocular lenses. However, monocular lenses offer a true field of vision.

Monoculars are usually designed to be precise at close range, so they don’t need a wide field of view.

Do monoculars zoom?

Monocular lenses are used by most photographers for taking pictures of wildlife, targets, or just enjoying nature. However, some monocular lenses are compatible with smartphones and let you take zoom-enhanced images.

Should I buy a monocular or a binocular?

Binocular telescopes usually cost less than monocular ones.

  • Binoculars are much better than monoculars for both day and nighttime use.
  • Monoculars are better for short trips because they don’t cause eyestrain. Binoculars are better for longer trips because they feel more natural to hold.
