Those whose life is inextricably linked with wearing glasses often faced such trouble as fogging glasses. The worst thing in this situation is that a special microfiber cloth is not always at hand, and because of this, improvised materials are used that can ruin the lenses. So why are they sweating and how to deal with it?
Why are fogging glasses?
Trouble can also be encountered along the way with athletes, such as swimmers or skiers. During physical exertion, the body produces a significant amount of heat, which, when exposed to cold temperature on the lenses from the outside, forms condensate.
How to handle glasses so that they do not fog up?
If you are not attracted by the prospect of constantly using improvised tools and wiping lenses while playing sports, then you should familiarize yourself with the most well-known ways to deal with this problem.
Soap
Liquid soap
For processing with liquid soap, a cotton pad and a drop of agent will be required. Soap is applied to the lenses and wiped dry with a cotton pad . Instead of a cotton pad, a small piece of flannel fabric is acceptable.
Glycerin
A good way to combat fogging is to use liquid glycerin. Glycerin must be warmed to room temperature and applied to flannel fabric . Next, the glasses are thoroughly wiped and left to dry. After drying, the glasses are wiped again, but with a dry and clean cloth.
Toothpaste
A pea of toothpaste is applied to the lenses and then wiped dry . It is worth noting that the paste is very difficult to wipe after drying. This method is very time-consuming, but if nothing else is at hand, then it can help out.
Antifog
What special tools exist?
Optical stores, pharmacies, as well as sports stores began to sell specialized anti-fogging products. The assortment includes sprays (Zero-Fog, Super-Optic, BPI No Fog, Snowter are more common) and wipes (for example, No-Fog Cloth). These funds provide a temporary effect . The composition includes surfactants that have a water-repellent effect. Thanks to the invisible film being created, the smallest particles of water do not settle on the surface, but roll off it.
What to do with glasses for the pool?
If the glasses are fogged up, but there is no money at hand, then the old folk method will come to the rescue. The inside should be moistened with saliva and rubbed with a cloth . Please note that it is forbidden to do this with your finger, otherwise there may be greasy marks. After processing, the glasses must be rinsed with plain water.
What not to do?
In no case should you use anti-fogging chemicals that were originally intended for mirrors, car windows or for the home . At best, aggressive components can harm fragile optics, while in the worst case, these components can damage the visual organ and the human body.
Advice
If glasses are not prescribed for continuous use, then in the cold season they are still better to wear in a durable and high-quality case. They can freeze in your pocket and will also be prone to fogging. If, however, the glasses are fogged up and there are no funds at hand, then leave them for a while . This will take about 5 minutes. They will warm up, and you can continue to use them.
If you have problems using glasses for winter sports, then check if the helmet does not block the ventilation holes. Otherwise, it will be necessary to replace part of the equipment.
