Tackling foggy lenses: Tips to keep your vision clear
Fogging of glasses is a common issue affecting many wearers. Why does this happen, and how can one effectively tackle this troublesome phenomenon? We'll provide some helpful tips.
Do you recognise that moment when entering a warm office from the cold outdoors, your glasses immediately mist up? Fogging of glasses is not only a cosmetic but also a practical problem that can significantly hinder daily activities.
Many glasses wearers wonder why their lenses fog up in certain situations and how to prevent this inconvenience. We often overlook simple rules that can notably improve the comfort of wearing glasses, irrespective 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 entering 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 occurs particularly in winter when temperature differences are at their 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 minimise fogging. These technologies can not only prevent fogging but also protect the lenses from scratches and dirt.
Also, consider whether your glasses are properly adjusted to your face. Ensure the nose pads and temples are properly adjusted so the glasses sit at the right distance from your face. This allows for adequate airflow, reducing lens fogging.
Another method is to use anti-fog sprays or gels applied to the lenses. A thin layer of the preparation creates a protective barrier on the lenses, which makes it difficult for water vapour to settle.
You can use liquid soap or washing-up liquid to clean the lenses. Once the glasses are dry, wipe them thoroughly with a microfiber cloth.
Another technique 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 proper storage and cleaning of glasses can help. Avoid using aggressive cleaning agents that could damage protective coatings. Special microfiber cloths are also useful for thoroughly cleaning the lens surface.
