I'm not familiar with the Bolle line, but if you are looking for sight fishing glasses, the best colors are green or amber. I used amber all the time for sight fishing, but since SolarBat came out with Mossback green a few years back, I will never go back to amber. The green cuts out almost as much light as gray in bright sunlight, but they allow enough light through to see in overcast conditions also, so I never change between lens color throughtout the day - I just keep the green on. The Mossback Green also highlights vegetation in the water, so it shows up really well. During sight fishing, the green on a bass' back stands out really well also. If Bolle has a green color, go with that. If not, check if they have a amber. If no on both, check out SolarBat. BTW - if your looking for polarized fishing glasses for sight fishing:
1) stay away from mirrored lenses. They do nothing for the view - purely cosmetic.
2) stay away from glass. You can polarize glass, and you can temper glass, but you CANNOT temper polarized glass - it will shatter. So if you have polarized glass, and get hit in the face with a bullet weight or spinnerbait, you have a much larger chance of losing an eye. Stick with Polycarbonite or Acetate..... Poly being my choice.
3) spend the money for a good pair. The boat, rod, reel, tackle doesn't do you any good if you can't see to use them.
All the best,
