Itâ€™s definitely an inconvenience when your goggles start to fog up whilst your swimming, which is why all Speedo goggles now feature anti-fog as standard. Caring for your goggles in the right way is paramount to preserving your anti-fog coatings for as long as possible, and hereâ€™s how.
Step 1 â€“ Why your goggles fog up
Goggles fog up because warm, wet air usually created from your body heat condenses on the lenses because the lenses are colder than the warm air.
The first step to achieving a fog free swim is to check your current goggles. In some cases where goggles are used on a very regular basis the goggles can out live the anti-fog coating. If you’ve had your goggles for a long time and they have been well used it might be time to consider investing in a new pair if you are having fogging problems.
Step 2 â€“ How anti-fog goggles work
There are two types of anti-fog coatings that we use at Speedo, anti-fog and anti-fog ultra. These coatings work by making it a lot harder for condensation to stick to the lenses. On PC lenses (hard lenses that donâ€™t bend at all, often the choice of competitive swimmers such as our IQ Fit range) anti-fog is sprayed on the inside of the lens. CP lenses (slightly flexible lenses designed for comfort such as our Biofuse range) are impregnated with an anti-fog ultra solution in the manufacturing process, as this is impregnated and not coated it will not wear away.
In order to maintain your goggles itâ€™s important to clean your lenses after every swim, and keep them safe in a pouch to avoid any scratching or rubbing. To clean the lenses gently wash them after every swim with luke warm water to remove any chlorine and other harmful chemicals. Leave the goggles to air dry and keep them in a case or box, this will help prevent damaging the lenses whilst they are in your kit bag. In the case of PC lenses (anti-fog coating), try to avoid rubbing the lenses dry or touching them as this will start to remove the coating.
Step 3 â€“ Other ways to prevent fog
If you look after your goggles from day one you will be able to preserve the anti-fog coating for a lot longer. Ensure your goggles are fitted correctly to your face and adjusted accordingly; this will help to stop any leakages.
To help you make the right choice when purchasing new goggles all Speedo goggles feature the anti-fog and anti-fog ultra logos.Â Always read your goggle instructions to ensure youâ€™re taking the right pre-cautions for the different types of anti-fog to preserve the coating – after all, they are a really important part of your kit!
