/ UV protection for spectacle wearers
After a previous unsuccessful go at wearing contact lenses (monthlies and two-weeklies), and various experiments with Coccoons and OTG goggles, I recently tried again when dailies became available in my prescription- fairly high and complex (up to -9.5) with astigmatism.
I can honestly say that they've been brilliant. I've worn them for alpine summer, lots of Scottish winter, and skiing (resort and nordic) and never had a problem even on very long days. The cost is far too much for me to justify them for everyday use, but for mountain days they're great - and you can get the sunglasses that actually fit rather than just the least worst option!
I thought the uv protection was important because prolonged/intense uv can damage the cornea, or am I wrong?

The contact lenses I use are UV blocking by themselves, but I still wear sunglasses (or goggles) so the whites of the eye don't fry, and to cut out glare
Try those driving style flip-downs that specsavers sell (have seen them in boots for a lot more). Check to see they fit the shape of your glasses first; last time I looked, there were only two shapes available. You could also put some 'leather side shields' on and they will be a sort of convertible glacier goggle?
I use wrap around prescription sun glasses which work OK but still mist up occasionally.
I also use the new Julbo googles which have a venting facility and are also photochromic and fit over my normal glasses https://www.julbo.com/en/10/products/masques/first-class/model/aerospace_11300.html and they work really well.

Yes that's right. The next key point is that when purchasing eyeglasses, UV protection is easy to include in the product. It would be difficult to manufacture a lense which blocked substantial percentage of visible light which did _not_ also block UV.
Therefore visible-light percentage is a critical _distingushing_ measurement, and UV percentage is usually not.
