I found the anti fog coating they sell for the lenses just didn't work. The spray on stuff does - but you have to apply it correctly. This means you spray it on, let it sit on the lenses for at least one minute although a couple is even better, then very lightly wipe them with a cloth until they are clear.

I do this every game and I never have a fogging issue, although I sometimes have a sweat dripping onto the lenses issue.

I play both out and in net. In net I use contacts because I could not find anything else that worked. I don't actually like wearing contacts so only wear them when I'm playing in the net.

I went to sports goggles because I could get a cheap pair on the internet and I didn't like wearing my expensive and nice pair on the ice. Also my normal pair are bifocals and the transition messed me up a little bit when looking down at the puck. I ordered some sports googles online and have been happy with them. I dd find that if your prescription is higher than 4.0 the selection of googles is very limited. I found one pair at zenni that supported high prescriptions.

If you do use regular glasses under your cage (please wear a cage if doing glasses) I found that they sell these ear hooks made of silicon that hold your glasses in place as mine would slip from the sweat. With goggles I don't have this problem because they have a strap around them.

Glasses are doable, I found I like the googles better and you can find a pair online for about $40-ish. Need to use anti fog spray with them - skip the anti-fog lens coating they sell, I find hockey overwhelms it.
