You can use an anti-fog spray or serum from goggle producers like Speedo or TYR. These are among the few goggle makers that create an anti-fog solution for goggles. Or spit into your goggles. By spitting or licking the inside lens of your goggles, you will create a barrier that prevents condensation. This is usually a temporary solution but is widely used.
