At the same distance, the higher the multiple, the greater the disparity and the smaller the visual field, the more obvious the shaking caused by breathing
On the contrary: at the same distance, the smaller the multiple is, the smaller the parallax is, and the larger the field of vision is, the slighter the shaking caused by breathing is
Our recommended range of novice multiples: no more than 6 times for 50m, no more than 10 times for 80m, no more than 16 times for 100m
Our recommended multiple range for advanced players: no more than 4 times for 50 meters, no more than 6 times for 80 meters, no more than 8 times for 100 meters, no more than 10 times for 120 meters
The above knowledge is a simple introduction to the relationship between parallax field of vision and multiple.
After understanding these relations, we also need to know that the same seedling, the same distance, the same multiple, different people to observe, the results are different. That's the difference in everyone's vision. The astigmatism of myopic and hyperopic eyes is different from that of normal vision, so the optical imaging that everyone sees under the same conditions is completely different.
We say that there are two terms of sight that we attach great importance to but have a very vague concept: "parallax" and "zoom error". These two words are completely different concepts.
First of all, "parallax" is the deviation between the differentiation line and the target caused by human shaking, which can be overcome by parallax adjustment function and self breathing control. And the better the lens, the more accurate the parallax control, and the more realistic the visual restoration.
And the most difficult thing to understand is the zoom error. In many years of sales, many players do not know what is called zoom error. So what is the zoom error? It's because everyone's vision is different, at different distances beyond their own eyes can withstand the maximum zoom range, resulting in optical distortion or displacement! That is to say, the image we get deviates from the proper position angle, so when we look out of the sight, we can see that the target is moving linearly. It's crooked. In fact, it's not the deflection of the seedling, it's the offset of the target position, which is caused by the excessive multiple.
In use, we will find that there is no such offset in a certain multiple interval at the same distance. For example, we can't see this kind of shift at 20 meters when we use 4 times observation and increase it to 5.6.7 times. Can be 8 times to see the target and the line has been offset. This is where the zoom error has occurred. This means that your eyes can't focus correctly at this distance and optical multiple.
Then we need to know that we should not exceed 8 times at this distance.
And this result only applies to you. Because each person's vision is different, the relationship between the multiple of distance is also different. For example, three people together, one is myopia, one is hyperopia, one is normal vision. Then, look at 50 meters with one seedling. Myopia should be able to 12 times without magnification error, hyperopia may have magnification error in 4 times, and people with normal vision may have magnification error in 8 times.
The above is the explanation of parallax and zoom error. Hope that players can understand these common sense, which has a very important help to the actual combat in the future!
After a new sight is in hand, we need to install, calibrate and debug it. But don't forget the most important point: test the zoom parallax.
At the distance of 20 meters, from the lowest point of view, the multiple increases continuously until the error of zoom appears. For example, when there is an error of 8 times, remember not to exceed this multiple.
At a distance of 50 meters, start from the highest multiple of no zoom error until there is a zoom error. For example, when there is an error at 12 times, remember not to exceed this multiple.
