Foggy sunglasses are always a big headache for most of us. Whether we come inside from outside in cold weather or participate in sports like running or riding, our sunglasses are covered with a layer of steam that makes it hard to see. You can wipe it off, but the vapor reappears once you put your sunglasses back on your face.
If you've ever experienced your glasses fogging up after a temperature change, then you know how frustrating it can be when you suddenly lose sight. Foggy glasses while driving or operating machinery can be a source of annoyance as well as a safety hazard.
Why do my glasses fog up?
The combination of cold air and heat can cause sunglasses to fog up, a common occurrence when exercising or in environments with rapid changes in heat and cold. Since we often sweat and heat up when we exercise, the heat will condense when it meets the cold mirror surface, which also happens when we walk from the cold outdoors into a warm room.
In addition, most regular sunglasses do not have any ventilation. The lack of ventilation can cause moisture to accumulate on the lenses of sunglasses, making them less conducive to travel or sports. Therefore, it is of great importance to use anti-fog sunglasses for ventilation and to prevent this problem. Here are a few ways you can try to keep your lenses fog-free in no time.
Purchase anti-fogging products to treat your sunglasses at home. Many companies make products specifically designed to prevent fogging of eyeglasses. They are usually sprays or gels that, when applied directly to your lenses, will reduce fogging by forming a barrier that prevents moisture from condensing.
These pre-treated cloths are both convenient and easy to use. In cold conditions, you can purchase some anti-fog lens wipes to keep your sunglasses from vaporizing while you are wearing glasses working outdoors. These wipes are for one-time use only and can be discarded once done.
If you don't have an anti-fog spray/wipes at home, try polishing your lenses with a bit of shaving foam. Apply a small amount of shaving cream to your lenses first, then wait for it to dry, at which point a transparent protective layer will form on your lenses to protect them from heat and cold.
Another fantastic trick is to scoop up a small amount of solid soap and wipe the lenses. Apply a small amount, let it dry, and then wipe it off with a cloth. Just like shaving foam, this will help build a transparent layer that will protect your glasses from the outdoor elements.
If you've just run out of soap and shaving cream, then you probably didn't think toothpaste would do the job! Just make sure it doesn't contain baking soda so it won't scratch your lenses. Sometimes touted as a home anti-fogging agent, toothpaste can prevent fog from forming, yet the small abrasive particles in some products, especially those containing baking soda, can scratch the surface of your glasses.
These short-term solutions will keep your lenses fog-free in a pinch. They're very effective when you need to fix a problem quickly but are not suited to solve a persistent problem.
