What kind of product is antifog?
Direct translation from English is “anti-fog.” In fact, you can't say more precisely. There are products that can remove the “fog effect” from the eyes, or rather, from the lenses. Old and proven methods - Lubricating glasses with toothpaste, baby shampoo or concentrated soap solution.
True, the effect of such products is quite doubtful even for glasses worn every day, and practically unsuitable for skiers or swimmers - and it’s not enough for one workout. But now a modern remedy has appeared - antifog. Expensive glasses are treated with it at the production stage, and if your glasses don’t have it, you can take it to an optician (an expensive pleasure) or process it yourself.
Liquid composition
Quite a lot of companies produce this miracle product. But the main components often intersect, only the accompanying ones change. Almost all antifogs include:
- water (more than 80% of it in the product);
- decyl polyglucose (for foam);
- polyurethane (allows the protective film formed on the glass surface to remain flexible);
- polyvinylpyrrolidone (for stabilization);
- methylpyrrolidone (as solvent);
- triethylamine (as a hardener).
The principle of its operation
This cocktail, when applied to glasses and then dried, forms a film that allows the glasses not to sweat for quite a long time. Thanks to its complex composition, the product is evenly distributed over the surface. In addition to the main function, such The film also protects the glass from exposure to adverse environments.. For example, dust does not accumulate on glasses treated with antifog; water drains from the glasses faster, leaving no drops or streaks.
There is no need to fear that such a “hard-to-read” composition will lead to allergies. Manufacturers use only substances that do not cause any reactions. But this is possible if you have an individual intolerance to the substances included in the composition.
Read the information on the packaging carefully! Antifog can be used to treat goggles for swimming, snowboarding, paintball, regular lenses for everyday wear, and sunglasses.
Important! Do not use car glass cleaner on your glasses. They may contain substances that can harm humans!
Types of antifog products
This miracle product is available in the form of a solution, spray or wipes. The latter are easy to use - wipe the lenses of your glasses and let them dry (this will take less than a minute). In addition, antifog will always be at hand. Usually there are from 6 to 10 napkins in a package, but they often sell one piece for testing.
The good thing about the spray is that dries instantly. It can be used immediately before training.You just need to carefully read the instructions before use and do not forget that after processing, for example, swimming goggles, they must be rinsed in water before putting them on.
The gel creates a more durable coating, but also takes longer to dry.
Important! Be careful - many solutions are made specifically for underwater masks. They have additional properties - they repel dirt and protect against dust, but not all of them can be used for regular glasses.
How often is antifog applied?
It all depends on the goals and what type of product you use. The most short-lived coating is created by napkins. A spray, gel or solution lasts for a longer period.
Most often you have to use antifog for swimming goggles. For professional training, the treatment may only last a few hours. For rarer, “amateur” use, the protective film will last for a couple of sessions. Regular eyeglasses may need to be re-treated only after a month or two.
Important! Correct handling will prolong the effect of antifog significantly. You just shouldn’t wash your lenses under a very strong stream of water, rub your fingers on the glass, or leave your glasses near heating devices.
