How to Prevent Fogging in Prescription Swimming Goggles


Swimming is a fantastic exercise and an enjoyable hobby for many. However, fogging in prescription swimming goggles can be a significant annoyance, impairing vision and diminishing the overall swimming experience. Fortunately, there are several effective methods to prevent this issue, ensuring clear vision underwater and a more enjoyable swim. In this article, we will explore practical solutions to prevent fogging in prescription swimming goggles, ensuring you can swim with clarity and comfort.

Choose Anti-Fog Coated Goggles

One of the most effective ways to prevent fogging is to invest in prescription swimming goggles that come with an anti-fog coating. These goggles are specially designed with a coating on the inner side of the lenses that minimizes the accumulation of water droplets in the form of vapor. This protective layer ensures clear vision by preventing fog from forming. When purchasing prescription swimming goggles, look for ones that specifically mention anti-fog properties, as they offer the best protection against fogging.

Pre-Treat Goggles with Anti-Fog Solutions

If your current prescription swimming goggles do not have an anti-fog coating, you can still prevent fogging by using anti-fog solutions. There are numerous anti-fog sprays and wipes available in stores that are designed to work on swimming goggles. To use these products, follow the instructions provided:

  • Clean the Goggles: Before applying the solution, ensure your goggles are clean and dry by rinsing them thoroughly with fresh water. Removing any dirt or debris ensures better adhesion of the anti-fog solution to the lenses.
  • Apply the Anti-Fog Solution: Spray the anti-fog solution or use wipes on the inner side of the lenses, covering the entire surface evenly. Be sure to follow the manufacturer’s recommendations regarding the amount of solution to apply for optimal effectiveness.
  • Let It Dry: Allow the solution to dry completely to form a barrier that prevents water droplets from forming as steam. Avoid wiping or touching the lenses until the solution has fully dried to ensure maximum effectiveness.

This simple pre-treatment can significantly reduce fogging and improve visibility underwater, enhancing your swimming experience.

Ensure a Proper Seal

A proper seal is crucial in preventing water from entering your goggles and causing fogging. Here’s how to achieve it:

  • Adjust the Straps: Ensure the straps are snug but not too tight. Overly tight straps can cause discomfort and distort the lenses, leading to poor vision and potential headaches. Adjust them to provide a secure yet comfortable fit that maintains the goggles’ position.
  • Check the Fit: The goggles should fit comfortably around your eyes, creating a seal that prevents water from leaking in. Test the fit by pressing the goggles gently against your eyes without using the straps and see if they stay in place for a few seconds through suction alone.

A well-fitted pair of goggles will minimize fogging by preventing water and moisture from entering the goggles, ensuring clear vision and a more enjoyable swimming experience.

Avoid Touching the Inside of the Lenses

Touching the inside of your goggles’ lenses can transfer oils and dirt, which can contribute to fogging. To keep your prescription swimming goggles fog-free, avoid touching the inner surface of the sports glasses as much as possible. If adjustments are needed and water gets inside, gently remove the water without making direct contact with the lenses. Minimizing contact will help maintain the anti-fog coating, preserve the lens clarity, and ensure a better swimming experience.

Rinse Goggles with Clean Water

After each swim, rinse your prescription swimming goggles with clean water to clean salt, chlorine, and any other residues that can cause fogging over time. Follow these steps for proper maintenance:

  • Rinse Thoroughly: Use fresh, clean water to rinse the lenses thoroughly, ensuring that all chemical residues and particles are completely washed away. This step helps prevent buildup that can contribute to fogging and degrade the lens quality.
  • Air Dry: Allow the goggles to air dry completely before storing them. Place them in a well-ventilated area to ensure that all moisture evaporates, which helps maintain the anti-fog coating and overall durability of the goggles.

Regular rinsing helps prevent the buildup of particles and residues that contribute to fogging, ensuring your goggles remain clear and functional for a longer period. Proper maintenance will enhance your swimming experience by providing consistently clear vision.

Additional Tips for Preventing Fogging

  • Use Baby Shampoo: A drop of baby shampoo on each lens, rinsed off lightly, can act as an anti-fog agent. The mild formula creates a thin barrier that prevents condensation from forming, keeping your vision clear throughout your swim.
  • Spit Method: Some swimmers use their saliva as a quick fix, coating the lenses with a thin layer before rinsing lightly. This method is convenient and accessible, providing a temporary anti-fog solution when you don’t have any commercial products on hand.
  • Store Goggles Properly: Keep your goggles in a protective case to avoid scratches and exposure to dust and debris. Proper storage helps maintain the integrity of the lenses and the anti-fog coating, ensuring they last longer and remain effective.


Maintaining clear vision underwater is essential for an enjoyable and safe swimming experience. By selecting prescription sports glasses with anti-fog coatings, pre-treating lenses with anti-fog solutions, ensuring a proper seal, avoiding touching the inside of the lenses, and rinsing them with clean water, you can prevent fogging effectively. These methods will help you swim comfortably and confidently.
