Named for the instrument that revealed what the eye couldn’t.
In the 1930s, the Eikonometer was a precision instrument that measured aniseikonia — the tiny differences between how each eye sees the world. It made the invisible measurable.
Eikonia is software in that tradition. From the Greek eikōn — image, likeness, icon — for the everyday work of an optical practice that’s full of small things that add up.
