1. A system for a light fixture comprising:
one or more light sources arranged on a mount; and
an optic comprising:
a first ridge structure, wherein the first ridge structure is disposed in a first region at a center of the optic, for diverging some light from the one or more light sources in a more outward direction from the center;
a second ridge structure disposed in a second region at an outer portion of the optic for directing some light from the one or more light sources in a less outward direction using total internal reflection, wherein a direction from the one or more light sources toward the optic defines a downward direction and a direction orthogonal to downward is outward; and
a reflector between the mount and the optic.
