Hello,
I like the style of the logo, however I think the eye mark on the left doesn't really looks clearly enough like an eye. Also, the two O, I don't really get what are symbolizing the 2 point over them.
The shape of the E of Eco is nice because it looks like € symbol, can you try too make it look little bit more like the euro symbol?
Maybe you can try to join the two O with a small bridge to make it look like a eyeglass frame, and also make a morea clearly identifiable eye at the beginning.
Thanks !
