In aspects described herein, the UGR of troffer-style lighting fixtures can be improved (e.g., reduced) through lens assemblies having one or more light redirection features configured to particularly redirect light emitted at high v-angles (e.g., light emitted sideways relative to the housing at v-angles greater than 70 degrees). For example, the lens assembly may include an inner prismatic surface of a lens, an inner lens, a louver assembly (e.g., over or under a lens), or a reflector to achieve this light redirection.
