I'm planning a ~year long trip across Europe and India, where I'm gonna need sunglasses in different climates and situations.

They need to be:
1) Have great protections for the eyes(Polaroid right? )
2) Be durable(So they don't break easily during the trip and so I don't have to worry about them all the time)

I was thinking about Oakley, there sunglasses seem to meet my needs.

Thx in advance, ZBBZ.
