Low reflectance glare optic

A rearview assembly for use in a vehicle for providing a rearward view from the vehicle, the rearview assembly comprising:

• a first substrate and a second substrate, wherein at least one of the first and second substrates include a partially transmissive coating;
• a light sensor disposed proximate the second substrate;
• a secondary optic disposed between the second substrate and the light sensor, the secondary optic comprising:
• a first surface facing outward toward the second substrate;
• and
• a second surface facing inward toward the light sensor, wherein the secondary optic controls the field of view of light received by the light sensor, and wherein the secondary optic provides for a reflectance of less than 30 percent in the direction outward toward the second substrate.

A rearview assembly for use in a vehicle,

• the rearview assembly comprising:
• a housing configured to be mounted to the vehicle;
• a rearview element disposed in the housing for providing a rearward view from the vehicle, the rearview element comprising:
• at least one substrate, and
• a window formed in the at least one substrate;
• a light sensor proximate the at least one substrate, the light sensor having a sensory surface aligned with the window;
• and
• a secondary optic disposed between the at least one substrate and the light sensor, the
• a first surface facing outward toward the at least one substrate;
• and
• a second surface facing inward toward the light sensor, wherein the first surface comprises a plurality of vertical flutes and the second surface comprises a plurality of horizontal flutes, wherein an orientation of the plurality of vertical flutes and the plurality of horizontal flutes provide for a field of view with a reduced reflectance.
