What Should You Know?

One of the most popular troubles that happen to binoculars is a double vision.

[wpsm_box type=”info” float=”none” text_align=”left”]
Double vision is an incorrect image, frequently looking like a disproportion between images, which both lenses produce (images are not lined up, amount of objects (2 instead of 1), skewed horizon, etc.).

The cause of double vision is deeply rooted in several facts:

  1. The price of binocs. The hard truth is that the owners of something cheaper more often have a deal with double vision in comparison to those who had a chance to buy more expensive models of binoculars. Therefore, try to choose the equipment among the responsible manufacturers, who always use high-quality spare parts during the production of different types of equipment.
  2. Incorrect equipment handling. This fact plays a vital role in causing the double vision problem. If the binocular is subjected to a fall or getting wet, there are a lot of chances for you to face this technical fault. Try to be careful with your binoculars and always hide it in a special case. There are plenty of different cases to choose from: made of leather, wood, synthetic materials.
  3. Your attempts to fix your equipment, not for the first time. It is a key element among these three facts. If you ever tried to fix it by yourself, don’t be surprised to see an incorrect image through your binocs one day.

If binoculars are out of collimation, the result will be poor image quality or, for instance, double images

Let’s Start Fixing

  1. Draw the target. The easiest way is to draw a “Plus” (+) with a black or red marker on the paper and hang it on the tree. You can “draw” it in your mind in case you have a good imagination and know your way around the place.
  2. Step behind, look through the binoculars to focus on the center of big + and be sure which of the lenses gives the incorrect image. In this case, you will see an image of +, which isn’t lined up. One of the lenses will show you the line, which is lower or higher than another one, according to the target.
  3. It would be better to do all these things using the tripod. The tripod can help you fix the binocular in the right position that will reduce merging for error.
  4. The next step is to loosen the lens screw using the screwdriver. Do it as slowly as you can to avoid damaging the lens.
  5. Remove the lens and make it clean with a wet and then with a dry reg. Put the lens back and spin the screw. Remember to not adjust the screw too fast because the lens can break.
  6. Check the result by looking at the picture of + again. If there are no jagged lines, you win. If not, read the next steps.
