Sunglasses can help enhance our views, while it’s annoying sometimes when you get indoors from outside, your sunglasses easily get fogged, or in humid weather, it would easily get fogged, and this would be dangerous for when we drive with sunglasses suddenly get fogged, what’s the reason? and how to keep sunglasses from fogging up? In this article, we have some tips for this.
Why Do My Sunglasses Fog Up?
Sunglasses can fog up due to a phenomenon called condensation. Condensation occurs when warm, moist air comes into contact with a cooler surface, causing the moisture in the air to turn into water droplets. This happens because the temperature of the sunglasses is lower than the dew point temperature of the surrounding air.
There are a few common situations where sunglasses tend to fog up:
- Temperature difference: When you move from a cold environment to a warmer one, such as going from outdoors in winter to an indoor space with central heating, the warm air inside can cause condensation on the cooler surface of your sunglasses.
- Humidity: High humidity levels contribute to the moisture content in the air. If the air is very humid, the moisture in the air can condense on the lenses of your sunglasses, particularly when there is a temperature difference between the air and the glasses.
- Physical activity: Engaging in physical activities that cause your body temperature to rise and make you perspire can result in increased humidity around your face. When you stop moving or cool down, the moisture from your sweat can condense on your sunglasses.
How to Stop Sunglasses from Fogging?
How do you prevent your glasses from fogging up? It can be an annoying issue, but fear not – there are some simple and friendly tricks you can try to minimize or even eliminate the fog. Check out our top tips for combating this pesky problem!
- Give your lenses a soapy wash: Did you know that washing your glasses’ lenses with soapy water can keep them from fogging up? It’s a tried-and-true trick that even medical professionals with glasses use when wearing masks. Just wash your lenses with soapy water, rinse, and gently dry with a cloth – and you’re good to go!
- Try anti-fog spray or wipes: Another option is using anti-fog spray or wipes specifically designed for glasses. These products create a protective film on the lenses, acting as a barrier to fog. Make sure to use products made for glasses to avoid any damage. You can even make a homemade anti-fog solution using white vinegar and distilled water in a spray bottle.
- Secure your mask properly: To avoid foggy lenses when wearing a mask, ensure your mask fits well. Opt for a snug fit or use a mask with a bendable metal strip at the top. This strip can be pinched around your nose for a tight fit, directing air away from your glasses. A tissue tucked under the top of your mask can also absorb moisture and prevent fogging.
- Adjust your glasses’ nose pads: If your glasses have nose pads, tweak them to sit slightly further from your face. This allows your breath to escape, reducing fogging. Experiment with moving your glasses up or down on your face for different levels of fog prevention.
- Care for your glasses: Smudges and scratches contribute to lens condensation. Handle your glasses with care, clean the lenses regularly, and follow proper cleaning techniques.
- Breathe downward: While not a long-term solution, breathing downward by holding your upper lip over your lower lip can help in a pinch. Blowing air downward sends it away from your glasses, decreasing fogging.
How to Keep Sunglasses from Fogging All Day?
If you want to prevent fogging of your sunglasses and make it last all day, you need to take these tips for lens choosing and preserving.
- Start by checking if your sunglasses have anti-fog coatings on the lenses. These coatings reduce the surface tension of water droplets, preventing them from forming fog.
- Additionally, ensure proper ventilation by selecting sunglasses with vents or openings that allow air circulation. If you wear prescription glasses, consider getting prescription sunglasses with lenses treated to resist fogging. Regularly clean your sunglasses with a lens cleaner or mild soap and water to remove oils and dirt that can contribute to fogging.
- When transitioning between temperature environments, allow your sunglasses to adjust gradually to minimize sudden temperature changes. For example, you can keep them on your forehead or in a case for a few minutes before entering a warmer area. By implementing these measures, you can reduce the likelihood of fogging and enjoy clear vision with your sunglasses.
Choose Sunglasses that Won’t Fog-up
There are many factors that you should know when choosing sunglasses, they can prevent fogging from the start.
1. Choose anti-fog coating sunglasses
Prioritizing sunglasses with anti-fog coatings on the lenses is essential. These coatings reduce the surface tension of water droplets, preventing fog formation.
2. Choose sunglasses with ventilation
Ventilation is another key aspect to look for. Sunglasses with built-in ventilation features, such as vents or gaps, promote airflow around the lenses, minimizing moisture accumulation and decreasing the likelihood of fogging. A well-fitting frame is crucial as it prevents warm, moist air from getting trapped between your face and the lenses, reducing the chances of fogging.
3. Adjustable nose pads
Adjustable nose pads can also contribute to preventing fog by allowing for increased airflow. Opting for sunglasses with a wraparound style provides a closer fit, minimizing the amount of air circulating behind the lenses and reducing the potential for fogging. While not directly related to fogging, sunglasses with an anti-reflective coating help to reduce the temperature difference between the lenses and the surrounding air, which can mitigate fog formation.
