Why Do Sunglasses Fog Up?

Before we dive into the solutions, let's quickly understand why sunglasses fog up in the first place. Fogging occurs due to the temperature and humidity difference between the inside and outside of your glasses. When warm, moist air comes into contact with a cool lens surface, it condenses into tiny water droplets, creating that pesky fog.

Now, let's explore how to combat this issue effectively.

  1. Choose Anti-Fog Coated Lenses

One of the easiest ways to prevent foggy glasses is by investing in sunglasses with anti-fog-coated lenses. These coatings create a barrier that minimizes moisture buildup on the lens surface. Look for sunglasses labelled as "anti-fog" when shopping for your next pair.

  1. Adjust the Fit

Properly fitted sunglasses can make a big difference in preventing fog. Ensure that your sunglasses sit comfortably on your face without large gaps. A snug fit can help to minimize the flow of warm air from your breath into the lens area.

  1. Use Anti-Fog Sprays or Wipes

Anti-fog sprays and wipes are readily available in stores and can be applied to your sunglasses. These products leave a thin, invisible film on the lenses, reducing the chances of fogging. Keep a small bottle of anti-fog spray handy for quick and easy application when needed.

  1. Try Soap and Water

A simple DIY solution involves cleaning your sunglasses with a mild soap and water mixture. Gently rub the soapy water onto the lenses and then rinse them thoroughly. The soap residue will act as a temporary anti-fog coating.

  1. Opt for Ventilated Frames

Certain sunglass frames are designed with built-in vents that allow air to circulate behind the lenses. These ventilated frames can significantly reduce fogging by equalizing the temperature and humidity inside and outside the glasses.

  1. Keep Your Face Cool

Another effective strategy is to keep your face cool, especially when wearing sunglasses in humid conditions. Try not to overheat by staying hydrated, using a fan, or taking short breaks in the shade to let your face cool down.

  1. Use a Moisture-Absorbing Insert

Moisture-absorbing inserts, such as silica gel packets, can be placed inside your sunglasses case. These inserts help to absorb excess moisture, preventing fog when you store your sunglasses.


Foggy sunglasses can be a real annoyance, but with the right tips and tricks, you can keep your lenses clear and your vision sharp. Whether you opt for anti-fog coatings, well-fitted frames, or simple DIY solutions, you're now equipped to enjoy sunny days without the foggy hindrance. Remember that the key to success is finding the method that works best for you and your specific circumstances.

By following these practical tips, you can bid farewell to foggy sunglasses and step out confidently into the sunshine, knowing that your stylish shades will keep your vision crystal clear. Say goodbye to fog and hello to a brighter, clearer world!
