and neither do I, I buy what I need for the environment I'm in. Just because a brand has a recognized name hardly makes it designer.

That is because of reflected light being horizontal in polarity, and disrupting that with polarised lenses can make moguls etc. more difficult to 'read'. A plain 'black' lens should be sufficient to mitigate the brightness of snow therefore, and an even cheaper pair should be adequate
Height makes a difference, UV intensity increases 13% for every 1000m gain in height. So what works well at a 100m in terms of light reduction won't work at 3000m. Plain black lenses might reduce the visible light but not necessarily the UV light which is the most harmful. The standards EN172 and EN170 define testing and classification of lenses for UV protection and light transmission so when I buy a pair of Bollès for example I know those tests were passed for the environment they're in. I don't know that for a pair of 10 quid glasses from the petrol station no matter how handy they are for driving down the M4.

Have you tried both?
People just like having brands that represent style and quality, not everyone thinks they 'need' the brand name.
Yes! I have got a pair of bolle, and my comments stem from the fact that I can't deduce any conceivable difference between them and my pair of Boots polarised, except the colour of the lens. My chagrin is enhanced by having being fooled into thinking I needed them in the first place, against my better judgement. I wish I'd had the sense to leave myself with more money in my pocket.
Excellent, so you must be a lot happier with those now. I tried to explain this above
http://www.j2ski.com/ski-chat-forum/posts/list/16/7349.page#62228 for interest. If your boots glasses match those tests then they're an excellent buy, mostly they won't as boots by default will sell you stuff safe for driving which by definition won't be safe for high light/high UV situations.
