no wee cant classify them into one group on the basis of eyes as it will be like the classification done by aristotle on the basis of habitat .this is not adequate as we cant get a clear idea of the whole group by looking at a single organism in thaat group .they should be classified in such a manner.

No we can`t group them together coz structure of eye in all these organisms is different.planaria has a rudementary eye which was light sensitivity .But later this was evolved to a spherical layer in insects.later a lens was developed in vertebrates.but octopus doesn`t have an blind spot.in humans a better&complex eye is developed.so as they are present in different structures we can`t classify them in same group
