Are these really necessary for a Mont Blanc topped fortnight in the Alps? will my Cat 3 sunnies do? No shops seem to sell them (illegal for driving in) - any ideas?

Mine have always been fine for me.

Got some cat 4's at tkmaxx the other day, they are apparently for playing volleyball but fit really nicely and have very low distortion. 10 quid.

Beware I sufferred for 10 days with a mild snowblindness from a few hours exposure without glasses while skiing in cloud at 2500m. I may be sensitive but it hurt a lot and my eyes were swollen and runny for a week.

MB is far higher and could be sunnier. For £30-£40 it's not worth spoiling your holiday

I seem to remember that cat 3 can be used for about half a day in bright conditions without problems.
To overcome this on a long day, walk for an hour using your left eye. For the second hour use your right eye. Repeat through the day.
Cat 3s should be ok

In reply to AnnaSpanna: I've been fine for 6 hours on a glacier, 3500 metres, bright sun, in cat 3's. I was wearing a sunhat when not wearing a helmet, and this blocks a lot of glare. Remember the sunblock too.

In reply to AnnaSpanna: Get Cat 4. For prolonged exposure I'd want them. I used Oakleys for a couple of weeks in the Alps the first time I went and my eyes suffered a bit.

I've used Cat3 sunnies in Antarctica in summer for 60 days a year for the last seven years and my eyesight is great, never had a problem. But then I don't seem to get snowblind in situations where others might. My partner took his goggles off for no more than 2hrs in the shade this year and woke up blind at midnight.
