This is less complicated idea. Logo is again based on braille. and it means EYE. And if you look that symbol then its actually is like an eye. Logo is more understandable now.
little changes. As i see you like elements like eye and people with crane. I wanted to avoid directly to use eye, because it will make it too familiar with optic logos. And using people with crane feels more like logo for the retirement home. Braille is something that is understandable and familiar to persons who are blind. And theres ways to make that logo readable to blind people. Its even usable in small format. If i but some people figures there with big eye or hands etc. i think if scaled down theres almost nothing understandable. But it´s your call and your vision. I just like less details and logo what is memorable. At least i can get a good logo for my portfolio :)
