Helps a little, but not nearly enough
on September 4, 2010
I purchased this very early this season to repair the anti-fog coating on my Speedo Vanquisher goggles. I have used this numerous times and it helps but it doesn't come close to the manufacturer applied anti-fog coating. Unfortunately, it only extends the time taken to fog up from 2-4 minutes to around 5-10 minutes (if you're lucky that it got applied properly). Once it fogs up and you have to dip it, it will continue to fog up every couple of minutes. Only once did the fogging recede without dipping and left a small hole for me to look through in the middle of the goggles (tunnel vision).
I have tried numerous techniques regarding dipping and not dipping both my head and/or the goggles before putting them on to see if it makes any difference which resulted in minimal differences in anti-fog duration. The bottle utilizes drops instead of a spray which makes it seem like you would have to use more of it in order to coat the surface since the surface tension is so great that it doesn't want to move around on the uncoated surfaces. I have also tried different application techniques, but nothing seems to help very much. Perhaps I had too high of expectations for this product -- the expectation that I could swim laps for at least 30 minutes without them fogging up. I wish there was a way for stores to re-coat (or initial coat) swim goggles as a service using a quality anti-fog coating and application.
