I happen to have Briko (used Bolle for many years), but that is hardly important. Look for these things in goggles:
1) Fit. They should fit nicely so that there are no gaps or pressure points anywhere. It is important for them to fit well around the nose without being too tight.
2) Quality. Unfortunately, price and quality go hand in hand. The model I selected is a compromise. Not the best in flat light (yellow is the best there, despite what AlexG said) and not the best in bright light. My lens actually darkens in bright light (I believe you call that phototropic???) and it is vermillion. The Bolle I had before were the same way.
3) Periperal vision and downward vision are important too, but that depends on the design, not the lense.
4) Fit with a helmet. I don't wear a helmet, so that was not a problem, but if you do, bring the helmet when you buy the goggles.
