Thank you for the feedback. #25 #27 #28 #29 attempt to combine the medical, eye and technology aspects into one icon. Further revisions can be made if required.
I like your designs. Please consider implementing some other reference to medical aside from a cross, or consider just referring to the eye and not a cross or any other medical. I would like to see some other basis for a logo, aside from just fine-tuning what you've already done. I think you can come up with some other ideas. Thanks!
