How to Get Moisture Out of Monocular? – Quick & Easy Guide

People often ask, how to get moisture out of monocular?

Let’s find out!

How to Get Moisture Out of Monoculars?

It depends on how you’re using those monoculars. If you’re just looking at birds in flight, then there’s no need to worry about keeping them clean.

But if you’re using them as a spotting scope, then you’ll want to be sure that they aren’t collecting water. You could try wiping them down with a damp cloth, but it might be better to invest in some lens cleaning solution.

Zeiss Monocular 6X18B T*

A Carl Zeiss monocle is considered a high-end optic because of its reputation for excellence. It commands a premium price.

It’s not just because of the Zeiss’s name on it. Does Zeiss really put its repu­tation into this tiny 6×18 monocular and make an excellent optical instrument? You might be wondering the same thing.

We really appreciate a good monocular because they’re so useful when it’s impractical to carry even a compact pair of binoculars.

We were amazed at the “Wow Factor!” when we first saw the new 6×18 binoculars. They’re so clear and detailed that they immediately stood out from the crowd. And since then, we’ve been able to spend lots of quality hours studying them.

Size and Weight

It’s definitely the size you may look for when buying pocket binoculars and small enough so that they can easily be carried in most ladies’ purses.

It weighs just two ounces (57 grams) and fits easily into a pocket or purse. You could carry it discreetly around your neck on a lanyard so you don’t have to worry about anyone seeing it.


We found that one or two internet sellers claimed that the 6X18T* Design Selection monocular is waterproof and one even went so far as to claim it is “fogging-resistant”.

However, our test showed that the monocular is not waterproof or “fogging-resistant”, but rather splash-resistant.

The supplied user’s manual states that it is “splash-resistant” and the Zeiss website says it is “water resistant – sealed off against sprays of water”.

These official statements are both accurate enough – we cannot imagine how the monocular could be immersed without letting some water into the unit through the focus mechanism described below.

Pocket Monocular

This pocket monocular features a soft, durable, water-resistant exterior made of genuine cowhide. It also includes an adjustable strap so you can wear it around your head or across your chest. When not being used, the monocular fits snugly inside its protective carrying pouch.

We know that the 6X18BSDS metal body is resistant to corrosion. This will be useful for our bird-watching buddies who take it with them when they go out on bird-watching trips to humid regions.


The Zeiss designers put the 6×18 B into production with a phase-correcting roof prism, fully multi-coated optics, including their proprietary T* anti-reflection coatings, and a 3-millimeter aperture.

They also included a wide field of view eyepiece with generous eye relief. These features combine to make this compact monocular one of the best performers in its class.


The FOV is 394 feet at 1000 yards (120 meters at 1000 meters), providing a 6.9-degree angle of vision. That’s about the same as a human eye can see, so if you’re watching something on TV, you’ll get an idea of what your eyesight would be like if you were viewing the scene through our lens.


We tested the resolution of the camera at various distances and found that the quality of the picture drops off significantly after about 100 yards (91 meters). At that distance, the resolution is only about half of what it is at the focal length of the lens.

With its 15mm eye relief and ability to accommodate most eyeglasses wearers, this Zeiss monocle will be comfortable for most people wearing glasses.

You might wonder whether it isn’t simply a tiny little thing underpowered at only six times the size. We think that 6x optical zoom is perfect for a small pocket monocular.

With an 18-millimeter objective lens, you get enough light-gathering ability to make out what you’re seeing, but not so much that your view becomes blurred. In other words, if it were bigger you’d probably miss out on lots of detail because the larger aperture would also magnify any movement in your subject.

With its easy adjustment, this monocular quickly adjusts from infinite to as close as 30 cm, qualifying it as a close-focus binocular. It achieves this by using two tubes, one inside another.


One end of each of these tubes fits into the other. At the front of the innermost one, there are two O-rings to prevent dirt and humidity from entering. These O-rings also help to hold the innermost part together. Inside the outermost one, there is a roof prism and an eyepiece.


Fine Focussing can be easily achieved by simply moving the objective lenses towards or away from each other. Coarse focusing requires a gentle push in or pull out of the objective lenses. When first examining the Monocular, we pushed in with unbridled enthusiasm and held the two parts apart.

We were then able to carefully, but effortlessly, fit them back together again. We’re not aware of anyone else who has ever done this before, but we thought we’d share our findings with you. You might also find it useful if you’re trying to get a good view through the eyepiece without having to move around too much.


A Zeiss monocle includes a limited lifetime guarantee that can be transferred to another owner. While it does not cover damage caused by abuse, accidents, or modifications made to the equipment, it covers defects in material or workmanlike quality for the entire period of ownership.

A certificate of authenticity is included, but it clearly states that ownership of Carl Zeiss lenses is voluntary, and not registering it will not reduce your limited lifetime, transferable guarantee. It also explains how to transfer your guarantee to someone else after you register your lens in your own name.
