Hello Folks! Welcome to a new lesson on how to use an anti-fog marker. Before we begin, here's a fun fact: the first-ever Swimming Googles was invented in the 14th century made of polished Tortoiseshells. Now let’s learn how to use an anti-fog marker.

  The science behind fogging!

Fogging up of swimming goggles is a common complaint. I have seen people wanting an exchange after only a month of their purchase. I have been swimming competitively for the past 5 years and I can tell you that there are no goggles out there that can completely remove fogging. Condensation is the culprit behind foggy goggles. Your goggles cool off in the water, but the area around your eyes heats up due to your body temperature. The combination of hot and cold causes water droplets to form on the inside of your goggles — which creates fog. 

What are Anti-Fogging products?

These are chemicals that prevent the condensation of water in the form of small droplets on a surface that resembles fog. Anti-Fogging products are available as spray solutions, creams, gels, wet wipes.

Here is a product which I have used personally and recommend to everyone facing the problem of fogging. : Nabaiji Anti-Fog Marker  

How to Use?

  • First, make sure your lenses are dry 
  • Apply the marker inside the lenses.
  • Leave the goggle to dry for 1 min
  • Immerse the goggle in water. I recommend using fresh or tap water. 
  • If you do long pool sessions and your goggles fog up during the session, dip them in the water again, a protective film will reform and allow you to finish your session in good conditions.


Here are few tips I follow for Fog Free goggles

  • Gently move the marker around the Lenses. 
  • Do not rub the lenses with your finger after application. The marker may not work properly if you do so. 
  • After the end of the session, dip the goggle in fresh water and keep it in a hard case.
  • Always keep your goggle away from direct sunlight. 


I have used this Nabaiji Anti-Fog Marker at Goa Swimathon 10km for over 4hours and with no regret. I am sure if you have this product and follow the guidelines properly you will have a long-lasting Fog-Free Swimming Experience!!!
