dont really think it works, my goggles still fog

It works great - even in the coolest water.  One application lasts at least a week for me.  Love it.

- You can apply this anti-fog the night before whatever it is you need anti-fog for. For example, if you have swim practice the next day, applying it the night before works perfectly, dry by the time you use the goggles.

- What''s really nice about this anti-fog is that it can last 2 days instead of the typical 1-day use.

- Instructions are on the back of the bottle so you don''t have to worry about that. You just put one drop of this thick stuff onto each of your lens and spread it.

- See other reviews about applying it right before your event. I''m not sure about eye irritation or quick effectiveness because my applications are always dry by the time I use them.

Worked as advertised. Very satisfied.

I use this defogger after every swim. It works perfectly. No complaints at all. Just takes a drop.

works well ,I use it every time.
