Here is my dilemma. I sweat pretty heavily while on the snowboard, and I have to wear prescription glasses. I've tried OTG goggles and once , and borrowed the fan goggles, they all work fine for a while, but eventually, my glasses end up fogging and from there on, it's beyond recovery. If I go indoors, put on the goggles and sit there for a bit before heading outdoors, it works for a while until it starts fogging up again. Also, my Rx glasses fog up very regularly when it's cold. I don't want to go the lasik route, and I really hate contacts.
I have been on glasses since I was a kid, and by now, I have very high spherical and cylindrical power, so getting a prescription ski goggle will be out of the question. I like the concept of goggle inserts, but I doubt they will help that much, and they are more of a one trick pony.
This brings me to sports goggles. They aren't meant for this task, but I am sure I can rock something like this. I checked with my local optician - they have a few frames in stock, and can get them RXed and tinted in the color of my choice. On the slops, if it get's cold, there is always options like ski masks, and balaclavas. And an added bonus, they can be used for other sports as well.
So, has anyone with glasses tried this approach? I am stuck to a single lens, but for the benefits, it's not the end of the world for me.
