My submission for your review. I've decided not to go with the over done "VV" icons. I've captured that "VV" in the overall all design which is "V" shaped. You'll also notice I've concentrated on vision aspect. I feel this an important aspect to capitalize on.
3 images to follow
1. black and white 2. 2 colour (orange and teal) 3. gradient and 3d version
#160 to 162 -- At first when I looked at the graphic, I thought it was an "a" laying sideways. Took me a few moments to figure out it was an eye. In my brief, I said I didn't want eyes to be used in the logo. Concentrating on the "vision" aspect is OK, but I don't want an image that represents vision as we see with the eye, but as we see with our mind.
#163 -- I've been hoping to see more ideas in a wordmark style, so thanks for trying that. This one doesn't capture any interest for me, though.
