Thank you for your entries. I like the darker blue option. I like the Connection between the letters AOT and the logo. I will eventually be wanting something that I can use with the company name spelled out and without it as well -- so a graphic that has meaning independent of the words "Advanced Ocular Therapeutics."
For those who participated in the recent contest for "Ocular THeranostics," the logo I am seeking now is the company that is the clinical arm or collaborator of that company. I'm not suggesting the logos merge in any way. I'm just letting you know in case the contest description sounds familiar.
