How do you select swim goggles?

I would like to start swimming for exercise. It’s been nearly 15 years since I’ve done some serious lap swimming so there are so many other choices out there these days. What does a tinted or mirrored lens do? I will be swimming in an indoor pool that has fairly dim light. Any suggestions for some speedo goggles?

Can anyone recommend me a good pair of swimming goggles?

I’m looking for something that’s comfortable and leak/slip resistant to wear for swimming laps (mostly freestyle and breaststroke) for 1 – 2 hours daily in an indoor pool.

Thanks
Thanks everyone, I went with the Vanquishers =]
