People who wear glasses not as a stylish accessory, but as an aid to making eye contact with the environment, know that lenses tend to fog up during sudden changes in temperature.
Explaining why glasses fog up when you step out of the cold into a warm room
Physicists say that a temperature of +5-10 degrees Celsius outside is enough for fogging of the lens – this means that you do not need a strong “minus” for such a process. Fogging of glasses occurs due to several reasons:
- temperature change – warm air settles on cold lenses, and condensation is formed;
- Self-fogging – cold air in the street meets warm air from your mouth, this causes the cold lens to be covered in a veil of vapor
- fogging – increased humidity in the air provokes condensation on the lenses even when outdoors.
Because of all these factors, people have to regularly take off their glasses and wipe the lenses, because it is impossible to see through fogged-up eyepieces.
Penny glycerin for fogging glasses
The first remedy you can use is the usual glycerin, which you can buy in any drugstore. You need to pour some glycerin into a container, put it on the stove, and slightly warm it. Then soak a rag in it, wipe the lenses on both sides and let it dry. After that, polish the lenses with a microfiber cloth. As an alternative to glycerin, you can use regular liquid soap – the technology is the same.
Popular tiphack to prevent glasses from sweating
There are several other remedies from the household – they, too, can be used to get rid of the problem of fogged lenses:
- hard soap – soap the lenses on both sides, wipe with a soft cloth rag;
- hair shampoo – dilute in water in a 1:1 ratio, soak a rag in the solution, wipe the lens, let dry, and wipe again;
- toothpaste – apply a small amount of paste to the lens, rub it, and wipe dry with a rag so that no streaks remain.
In addition to the above methods, you can take the path of least resistance and buy the spray “Antifog” with which to treat the lenses of glasses. Such an industrial “anti-fog” will definitely help you, but it does not cost a lot.
Under no circumstances should you use any products for cars or mirrors. Their composition is too aggressive for the thin lenses of glasses and can deform them as well as worsen the quality of your vision.
