This can be frustrating and hinder the overall experience. In this comprehensive guide, we will delve into the causes of foggy goggles and provide you with effective strategies on how to handle this issue while underwater.

Snorkeling Mishaps: How to Handle Foggy Goggles Underwater

Understanding the Causes of Foggy Goggles

Before we dive into the solutions, it’s important to understand why your goggles may become foggy. Foggy goggles occur when there is a temperature difference between the water and the inside of your goggles. This temperature difference causes condensation, resulting in foggy lenses. Additionally, other factors such as improper fit, inadequate preparation, or low-quality goggles can contribute to this issue.

To combat foggy goggles, it’s crucial to address these underlying causes. By doing so, you can prevent foggy lenses and enhance your snorkeling experience.

Choosing the Right Goggles

Selecting the right goggles is the first step in preventing foggy lenses. Look for goggles that are specifically designed for snorkeling, as they often come with anti-fog coatings or features. These coatings work by minimizing condensation and maintaining clear visibility underwater.

Ensure that the goggles fit snugly on your face without causing discomfort. A proper fit creates a seal that prevents water from entering and reduces the chances of fogging. Consider trying on different goggles and opting for a pair that suits your face shape and size.

Preparing Your Goggles Before Snorkeling

Properly preparing your goggles before getting in the water can significantly reduce the chances of foggy lenses. Follow these steps to ensure your goggles are ready for your snorkeling adventure:

  1. Rinse the goggles with clean water: Before each snorkeling session, rinse your goggles with fresh water to remove any debris or residue.
  2. Apply a defogging solution: Anti-fog solutions are available in most snorkeling or dive shops. Apply a small amount of the solution to the inside of your goggles and rinse them with water. This creates a thin, transparent film that prevents fogging. Remember to follow the manufacturer’s instructions for the specific solution you are using.
  3. Avoid touching the inside of the lenses: Touching the inside of your goggles with your fingers can transfer oils or dirt, which can contribute to foggy lenses. Handle your goggles by the straps or outside frame to maintain cleanliness.

Techniques to Prevent Foggy Goggles Underwater

While proper preparation can minimize fogging, it’s also important to utilize techniques while snorkeling to maintain clear visibility underwater. Here are some strategies to help prevent foggy goggles:

1. Equalize the temperature

Just before entering the water, place your goggles on your forehead or hold them in your hands to equalize the temperature with your body. This minimizes the temperature difference and reduces the chances of fogging when you put them on.

2. Avoid breathing into the goggles

Breathing into your goggles can introduce warm, moist air that can cause condensation. Instead, exhale through your nose or use a purge valve on your snorkel to release any excess air. This helps to maintain a consistent temperature inside your goggles.

3. Keep your snorkel dry

Water entering your snorkel can increase the humidity inside your goggles, leading to foggy lenses. Practice proper snorkel clearing techniques to keep your snorkel dry. This involves forcefully exhaling through the snorkel to clear any water that may have entered.

4. Use saliva as a quick fix

If you find your goggles fogging up during your snorkeling session, a quick fix is to spit in your goggles and rub the saliva around the lenses. Rinse the goggles with water before wearing them. This method provides a temporary anti-fog layer and can help improve visibility.

5. Take breaks

If you notice your goggles becoming foggy, take a break from snorkeling and let them air out. Removing the goggles from your face allows them to equalize with the surrounding environment, reducing the fogging effect.


Foggy goggles can be a frustrating issue while snorkeling, but with the right techniques and preparation, you can minimize this problem and enjoy crystal-clear underwater views. Remember to choose the right goggles, properly prepare them, and utilize the strategies mentioned above. By following these guidelines, you’ll be equipped to handle foggy goggles and make the most of your snorkeling adventures. Happy snorkeling!
