Virtual and Mixed Reality platforms such as Meta Quest and Apple Vision Pro have accessibility challenges for Blind and Low Vision (BLV) users due to their dependence on visual cues. Existing accessibility features like color filters and text resizing have limited support which makes users with severe vision loss unable to fully engage. In this research, a novel solution has been developed that integrates 3D scenic descriptor generation within Unreal Engine User Interface using a modular client server architecture. The developed system implements a locally hosted Vision Language Model (VLM) to generate scene descriptions. During the comparative testing of VLMs, Llava 7B was identified as the most effective in balancing semantic accuracy and perceptual quality. A key innovation is a multi-prompt strategy that can guard rail the complex scenes into structured and comprehensive audio segments that cover objects, spatial layout, and mood. As the functionality of scene description is activated with a simple key press, the system provides tailored feedback that enables BLV users to integrate with VR environment independently.
