Very simple design, and I like it. In some ways, it is a little generic and safe, but the flipside is that it's a familiar format that is reassuring and very easy to read. I wish the color logo part would more clearly establish a mental or visual link to our field (eye care). Overall, a nice design.
Thanks for the revision. Adding the conical feature at the left end of the logo does perhaps make it more like an eye, but it's now pointy and now less desirable than your original design. Again, I find your original design high on legibility and ease of recognition, but the logo needs to be made a little more prominent, not just lengthened or stretched. Please consider a way to incorporate the eye theme a little more. Thanks!
Simplicity is good, but I think the current versions are a little too simple. Please see my comments regarding other designs, and I think you'll get a good idea of what type of features are interesting to us. Imaginative eyeshapes, 3-dimensionality, etc. Thanks.
