This is a summary of a paper in which we explore how to reliably measure the edge of the visual field and what effects do contrast and color have on this threshold. Most importantly, we demonstrate that cones are functional in this region.

We have very little introspection into what can be perceived at the edge of the visual field. Psychophysical experiments and the anatomy of the retina suggest that some interesting and unintuitive phenomena take place in this region.
