An “ophthalmo-digital system” is a transpheral functional unit consisting of elements of the digital infosphere on the one hand and the organ for visual perception of living beings on the other hand, which are connected to each other in a way that enables interaction directed towards the fulfilment of a function, a purpose or a task.

The term “ophthalmo-digital system” was coined as part of the terminology of the “Digital Era Framework”. In this reference framework, four spheres are distinguished on the basis of the type of information manifestation, on the basis of which a classification of systems can take place: The infosphere, which consists of the analog infosphere and the digital infosphere, the cognisphere and the entisphere.

Since the spheral classification of sensory organs depends on the view, different spheres can be involved: If the physical materiality of the organ is taken into account, it affects the biosphere and thus the entisphere. If a functional perspective is taken, a involvement of the cognisphäre is to be noted.

The term “ophthalmo-digital system” refers in particular to systems that establish a direct connection between the brain and the media of the digital infosphere.
