The anti-fog coating of goggles seems to work only for a few weeks. Even if you are careful not to scratch it off, it seems to attract dirt and make the lens "foggy" anyway. So, soon you better end up scratch off all the coatings. I just wonder if it makes much sense to get anti-fog goggles unless it's just for a short period of time? I use soapy water to rinse goggles before putting on, and it has worked better without a single fail instance. I'm debating to myself whether to scratch off the coating of my new goggles which have already become "foggy" because I can't touch the lens to clean the dirt that's been attracted by the coating.
If your clock is so far away you can't see it with some fog, move it closer.
How often is this practical? I'd say in the vast majority of pools the clocks are permanently mounted--or at least effectively so. Not being able to see the clock clearly is the thing that bugs me about foggy goggles. It's only in rare cases that my goggles fog so badly I have difficulty judging turns.
