Abstract: In our previous work the occlusion phenomena were considered as a base for development of geometrical structures in the visual field. Laws of occlusion were formulated and converted thereafter into axiomatic system. Occlusion is formalized as a ternary relation and among the laws of occlusion we find a requirement of symmetry of the relation (Gibson's law), a transitivity axiom and others. This leads us to a notion of abstract visual space (AVS). The geometry of AVS is the subject of this research. Typical examples of AVS are convex open subsets of an n-dimensional real affine space for n $GREQ 2, or more generally speaking, convex open subsets of any n-dimensional affine space over some totally ordered field F, commutative or noncommutative one. !12
