Not completely sure if this should be in General Ski Discussions but I'll try it here.
Like many of you out there I'm a glasses wearer. It's a mixture of a vision problem since childhood and deterioration with age. I've generally managed to get by relying on the brightness of the environment up in the snow but gradually over recent years I've found losing definition more and more of a problem, partticularly in poorer light. On a bright day I can still cope.
I initially bought a pair of Adidas Yodai goggles and put in the optical inserts with my prescription. In good light on a moderately cold day they worked well and it was a revelation to see clearly. I can, however, manage in these conditions as I've already said. As soon as a mist came down or there was any precipitation or even when I was working hard and getting hot, they misted up and made for a very unpleasant ride. I tried treating the lenses of the inserts and goggles but this made very little difference.
I then read a review of the Smith Knowledge Turbo fan on here a while back and parted with £110 (about $175) to buy a pair. I went to Sweden at new year and had no success with them so reverted to no glasses again. They were misting up in all conditions. I've just come back from Austria and tried the Smiths again with no better success. They mist up as soon as I stop even with the fan on full and take a couple of hundred metres skiing to fully clear. Not nice particularly in one of the busiest weeks on the slopes I've ever witnessed! I went back to the Adidas which were ok as the conditions were clear and cold enough up on a glacier.
Is there anybody out there who has had these issues and managed to find a workable solution? I guess the eyes will get worse as I age and I want to find an alternative to relying on good light before that's not enough.
