Professional logo design needed

I need a new logo for my site about optometry. There is a draft of my first idea attached and I need someone who can add a professional and stylish look for it. You don't have to use the draft exactly for your work, it's just an idea to show in which direction you should be moving with your work. Maybe adding a shadow to the abstact eye would look nice as you can see in the example (second file). It's important for me that the graphics and the text integrate well and correspondend with each other. But Feel free to use your own ideas with this. Delivery should be as psd-file so that i can change the background if necessary. Please show some examples of your work. Thanks.
