Anyone found any effective and lasting anti-fog methods for goggles ?

So far, spit i think is unhygienic, baby shampoo i think not good long term getting into the eyes.

Thanks, where to buy ? Online order ?
I see some made-in-china ones, but don't dare to try, later eyes got problem, finish.

Most of us just use cable tie, then cut off the excess. Works pretty much the same, just don't look pretty.
But inside pool, cannot see it anyway.

You don't need to be able to stay stationary at the deep end. Just swim normally lah....
The fear as you said is just psychological. I see some very good swimmers, but went come to deeper water they become scared.
