Hi,
Thank you all for the suggestions.
You tought me of the Wiley X brand, and I bought the B-2 model.
I got two lenses: polarized and clear.
Changing the lenses is very easy, and takes less than a minute.
I used them for a month now, and I like them.
I now use them as my sole sunglasses. Even when not on the bike.
One minor thing worth noting: The rubber pads of the frame goes off too easily.
Maybe I'll tape it when riding or something.
Tal.
