I had a pair of the blue reflective that had some small scratches develop so bought the blue and gold set. A very good value, IMHO. There are a few things to know:

1) They are not damage proof, no sunglasses are but are quite solid. The problem with ANY wrap around glasses is that if you drop them, they will usually hit the ground lens down so are a bit more likely to scratch than non-warp-arounds. Just the name of the game with wrap-arounds.
2) The optics are quite good and only by close comparison to high quality lenses would you notice the difference and then only a tiny bit. They are about 90% as good as my similar Oakley's
3) Choosing between the blue reflective and gold (yellow) is based on what you want things to look like. Blue and yellow are opposites so with the blue reflective it will block (reflect) blue and transmit yellow and with the yellow reflective it will block (reflect) yellow and transmit blue. So the image from the blue ones will appear more yellow and green where the image from the yellow ones will appear more blue. The downside to the latter is that since atmospheric haze is blue, this shows more with the yellow glasses where the blue glasses tend to "cut thru" the haze better.
