Abstract
Light transmissive structures include a light transmissive substrate that includes optical microstructures. The optical microstructures have a geometric feature that is configured to reduce glare in light transmitted through the light transmissive structure. Moreover, the plurality of optical microstructures also have a geometric feature that is configured to vary randomly and/or pseudorandomly across the light transmissive substrate so as to diffuse light transmitted through the light transmissive structure. Related fabrication methods are also described.
