Anti-Fogging: Skiing down from the top of the mountain in Zermatt early this January, it was minus 15 'C with some wind. No fogging at all, even when stationary! Tint: Yellow verging on grey tint meant that eyes soon got used to them and colouration did not ruin views. Clear skies, direct sun. No eye strain, even when coming over a brow of a hill on a lift and finding myself facing the sun. My girlfriend reported similar findings, although when I tried I found that the extreme colouration was more difficult to get used to and I would imagine that distinguishing yellow snow to avoid sitting on it would be more difficult. :-) Not quite so good in heading directly towards the sun but not so much as to be annoying. Polarising lens: When it was very occaisionally overcast, neither of us had any difficulty distinguishing bumps and ruts and changes in snow conditions. Indeed, we both used goggles on a late ski down to resort level, in near-dark at about 17:30 (it is a north facing resort). It was also very easy to distinguish changes in snow conditions from packed snow to ice, no doubt thanks to the polarising lens.

Did not find any weakness in the product. Check the size suits your face, and that it will cover your balaclava. Porting of air is not present on these models, however, I didn't encounter any problems (although occaisional misting on the outside if I breathed too hard into my jacket, that can't be helped by any treatment though :-) Consistency and availability, the product range appears to change and the carerra web site doesn't help much. Limited descriptions (verging on inaccurate, polar vs reactolite in particular seems confused as logos don't match description which does not match lenses found in the shops) I have decided that Diva, Divo and Corona are all the same frame.

I had Polarising yellow ultrasight Corona (£55) with black frames, my girlfriend had Polarising light yellow ultrasight Divo (£35) with liquid yellow frames. Yellow ultrasight is almost grey, need to look very hard to distinguish the yellow tint. Divo, light yellow ultrasight is coloured like those old driving glasses, get the picture? Apparently Divo is gents, Corona is ladies (relationship to Diva is unknown). They all look the same when held back-to-back; the only difference I could see was strap design and frame colour and that the Corona had a more useful strap clasp. Fantastic in poor light, great in bright light, ok in clear-skies. Took sunglasses, never used them even though there was not a cloud in sight on most days. Cheapest polarised lens I found, would need to spend a fortune to get a similar quality lens on say Oakley. Also, found the large, cover-your-face approach of all the other vendors a little unimaginative. The sun tan marks I had at the end of the holiday were not much worse than glasses.
