External fogging

Practical Tips about How to Keep Binoculars from Fogging Up?
Fogging of binoculars is a headache – and its treatment lies in preventative measures. You should let the binoculars get fogged up in any way. With proper care and steps, you can definitely make your optics safe from fogging of optics.
1- Keeping your binoculars dry
Fogging of lenses is due to their moisture and humidity. When you go out in such places moisture is around the corner, then you should keep binoculars dry by wiping all the moisture with the help of a microfibre cloth.
Keep in mind not to wipe the lenses harshly as your binoculars can get scratches. The continuous drying of binoculars will keep moisture away – ultimately making your binoculars not get fogged up.
2- Apply anti-fog products on binoculars
Anti-fog products are very useful that securing your optics’ moisture and keeping them safe from fogging up. You can get anti-fog products from any local optics store. Make sure not to use them too often as their excess can have a bad impact on the lenses.
Note: Use anti-fog products according to the recommendations of manufacturers.
3- Spit on your binoculars
It may sound weird but it really works in keeping moisture away from your binoculars. Spit when you feel like your binos are getting moisture and dry it with a microfibre cloth. Keep spitting and cleaning to ensure that they don’t get fogged up.
4- Use A Desiccant
Desiccants are a good way to keep your binoculars away from fogging up. The most popular desiccant are rice and silica. If you don’t have much time then put your binoculars in a jar with desiccant and they will absorb all the moisture from your binoculars – making them safe from fogging up.
5- Keep them in a Dry Environment
If binoculars are not fog proof then we recommend you to use them in those places where moisture is not common or temperature change is not too rapid. Keep in mind that care is better than treatment.
Use Fogproof Binoculars
Going out and choosing binoculars that are not fog proof is like wasting your money. Those optics that come with water or fog proofing is not worth the money. We always recommend everyone check the gas purging in the specification written on the box.
Those optics that are not purged with nitrogen or argon should not be bought at all. No matter if you buy binoculars from an online e-commerce store or any local optics store, make a wise decision.
