THanks for submitting this logo. I like how clean it looks and the sans serif font. While the black "pupil" is anatomically correct I'm not sure how it plays in the logo. Also, the blue portion looks like a ribbon. I'm not sure where you're located but in the US (and elsewhere??) a blue ribbon that sort of looks like the logo has become a symbol for prostate cancer advocacy, research, etc.
But the overall look we like. THanks again.
