Techniques described herein are directed to adaptive virtual reality and augmented reality viewing based on a user's eye condition data. In a first implementation, a software application renders video content based on the user's eye condition data by mapping the user's eye condition data to video rendering parameters. The video content rendered based on the user's eye condition data may be made available to a virtual reality/augmented reality player and played using a head mounted display. The video content rendered based on the user's eye condition data may be pre-rendered before video content playback or rendered in real time during video content playback. In an additional implementation, the head mounted display may be calibrated and adjusted based on the eye condition data prior to video playback.
