The brand I used was
Sea Vision but they all work about the same.
I just called a local dive shop and they cautioned that if you have plastic lenses you need to purchase defog that will not harm them. Not all defoggers qualify. They carried Aqua Sphere that works with plastic. $4.95 per bottle retail.
