Optics myths and misconceptions

 

Many myths and misconceptions are going around about our eyes and optics. Sometimes these are things we heard from people who didn’t have the right information. As the myths can go all the way into the binoculars and scopes category, making sure that the info you have is correct is the first step before purchasing a new device.

If your goal is pursuing an activity such as bird watching, then you might want to take a look at some of the things we listed below. The important thing to keep in mind is that more sources of information usually account for a better grasp of what is true and what is just a misconception.

Higher power binoculars will allow you to see more

The usability of a pair of binoculars is limited by the steadiness of the hand holding it. If you just ran up the hill in order to get a better look at a certain bird, then most probably your hands will not be steady enough for you to look at it properly.

Many experts believe that bird watchers can see just as much or even more with 8 power binoculars, or even 7 power. To get just a sense of how much the shaking of the hands can degrade an image, stabilize your binoculars on a tripod and see how much more detail you can observe.

 

A larger objective lenses offers a wider field of view

The field of view in binoculars is determined first by the magnification; the higher the power, the narrower the field of view. This is natural as we all know that when we zoom into an image, the level of details is greater, but the overall range of elements we get in the image is smaller.

Eyeglass wearers will experience the field of view quite different, as they face a different situation compared to those who don’t wear glasses. The most relevant test is to simply look through the binoculars and note what you can see from left to right.

I don’t need waterproof binoculars

Having waterproof binoculars is a good idea, even if you never go out in the rain. When warm, moist air comes in contact with a cool surface, water condenses, leading to your binoculars fogging up on the inside. This usually happens if you go from a cool environment, such as an air-conditioned car or house, into a warm or moist one, such as outdoors on a hot summer day.

A waterproof binocular is a very good solution to prevent this as the product is prepared for significant changes in temperatures by being sealed and filled with a dry, inert gas that contains no water vapor to condense inside.
