Abstract

We present a varifocal system for generating consistent accommodation cues and providing prescription correction in Virtual Reality Head-Mounted Displays (VR HMDs). The proposed approach mitigates the Vergence-Accommodation Conflict (VAC), a fundamental cause of discomfort in today’s VR, and eliminates the need for corrective eyeglasses inside head-mounted displays. We augment traditional objective lenses with a focus-adjustable optical system based on Alvarez lenses, and demonstrate a proof-of-concept integration into a commercial mobile VR headset. This paves the way to lighter, thinner, and more comfortable headsets, enabling the prolonged use of VR with minimal visual discomfort.
