The Science of Fog: Why Glasses and Goggles Fog Up

Foggy glasses, goggles, and helmet visors are more than an annoyance, they can be dangerous. Whether you’re cycling, skiing, riding a motorbike, or wearing glasses with a mask, fogged-up lenses reduce visibility and increase risk. Understanding why fog forms and how to prevent it can make a huge difference.

Why Do Glasses and Goggles Fog Up?

Fog occurs when warm, moist air meets a cooler surface. Your glasses or goggles act as that cool surface, causing water vapour in the air to condense into tiny droplets. These droplets scatter light, creating the hazy effect we call fog. Common situations include stepping outside on a cold day, entering a heated room after outdoor activity, or sweating during sports. Fogging can happen almost instantly, making clear vision difficult or impossible.

How VisioFog Anti-Fog Wipes Keep Vision Clear

VisioFog Anti-Fog Microfibre Wipes are specially formulated to prevent fogging on glasses, goggles, and helmet visors. Developed and validated in our R&D laboratory, they provide a high-performance solution that keeps surfaces clear for 8–10 hours. One wipe can be reused multiple times, up to 200 uses on glasses, 180 on goggles, and 150 on helmet visors.

Applying VisioFog is simple:

• Take out the wipe from its zipped pouch.

• Apply to the surface by pressing firmly onto your lenses or visor.

• Store for reuse by returning the wipe to its pouch and zipping it closed.

The wipes are safe for all optical surfaces and make fog prevention effortless, even in sudden temperature changes or high humidity.

Practical Tips for Fog-Free Vision

To get the best results, clean your lenses or visor first using VisioCrystal Surface Cleaner. Avoid breathing directly onto lenses when wearing a mask, and maintain airflow inside helmets or goggles when possible. Combined with VisioFog, these steps maximise visibility and comfort.

Why Clear Vision Matters

Foggy lenses don’t just obscure your view, they increase the risk of accidents during sports, riding, or daily life. With VisioFog, you can ride your motorcycle safely in wet conditions, ski or snowboard without constantly wiping goggles, and wear glasses comfortably in sudden temperature changes.

Fog is a natural phenomenon, but it doesn’t have to compromise your safety or comfort. VisioFog Anti-Fog Wipes provide a reusable, long-lasting, and easy-to-use solution for glasses, goggles, and helmet visors, keeping your vision clear so you can focus on what matters.
