How to keep your glasses clear and fog‑free all year round
Fogging of glasses is a common issue affecting many users. Why does this happen, and how can one effectively deal with this troublesome phenomenon? We'll give you some tips.
Do you know that moment when you enter a warm office from the cold air, and your glasses immediately fog up? Fogging of glasses is not only an aesthetic issue but also a practical problem that can significantly hinder daily functioning.
Many glasses wearers wonder why their lenses fog up in certain situations and how to prevent this inconvenience. We often overlook simple practices that can significantly improve the comfort of wearing glasses, regardless of weather conditions. So, what can you do to prevent your glasses from fogging up?
Why do glasses fog up?
The most common cause of glasses fogging is a sudden change in temperature. When you enter indoors from a cold environment, the moisture from the warm air condenses on the cold surface of the lenses, creating a layer that impairs vision. This happens especially in winter when temperature differences are the greatest.
What to do to prevent glasses from fogging up?
One of the key elements to consider when choosing glasses is the coatings on the lenses. Modern lenses are often equipped with anti-reflective or hydrophobic coatings that minimize fogging. These technologies can not only prevent fogging but also protect the lenses from scratches or dirt.
Also, consider whether your glasses are properly adjusted to your face. Make sure to have the nose pads and temples properly adjusted so that the glasses are at the right distance from your face. This will allow for free airflow and reduce lens fogging.
Another method is to use anti-fog sprays or gels that are applied to the lenses. A thin layer of the preparation creates a protective barrier on the lenses that makes it difficult for water vapour to settle.
You can use liquid soap or dishwashing liquid to clean the lenses. Once the glasses are dry, wipe them thoroughly with a microfiber cloth.
Another method that helps reduce glasses fogging is to coat them with glycerin. Wipe the lenses with a cloth moistened with glycerin, wait a moment, and then polish them with a dry cloth. Glycerin is available at pharmacies.
Taking care of the proper storage and cleaning of glasses can help as well. Avoid using aggressive cleaning agents that can damage protective coatings. Special microfiber cloths are also useful for thoroughly cleaning the lens surface.
