After launching Vision Pro, Apple released a series of support documents explaining how to use the device and what to do if you experience motion sickness or discomfort while wearing the headset.VisionPro users who experience visual discomfort, such as blurred vision, double vision, dry eyes, tearing, light sensitivity and eye fatigue, should stop using VisionPro and wait for symptoms to subside.
To minimize visual discomfort, a good fit is essential, with balanced pressure on the bridge of the nose and cheeks, and correct alignment set. When you start using Vision Pro, you should keep it short, and Apple recommends taking regular breaks every 20 to 30 minutes.
Apple also says it helps to keep your head upright rather than tilted to one side or the other and to sit upright when watching 3D movies, immersive media, or spatial videos.
Vision Pro is designed to "accommodate" a range of interpupillary distances, but Apple says some people with interpupillary distances outside of this range may experience visual discomfort when using the headset.
Apple recommends that people with certain medical conditions use caution when using VisionPro. The headset should be used in a "controlled" indoor or outdoor space where there are no obstacles to trip over or hit with your hands. Apple warns that door handles and cabinets can catch the power cord and cause it to disconnect.
VisionPro should not be used in extreme temperatures, rain, fog, or any humid environment, and water damage is not covered by the warranty. VisionPro should also be used in a well-lit area for the best experience, as poor lighting increases the risk of object collisions. VisionPro batteries should be placed in a well-ventilated place to avoid excessive temperature.
A small number of people "may experience motion sickness-like conditions when using VisionPro. Symptoms include dizziness, nausea, decreased consciousness, stomach upset, increased salivation, headache, fatigue and sweating. It may take 30 minutes from use to the onset of symptoms."
People suffering from motion sickness should stop using the headset and try not to use VisionPro on airplanes. Using the device for a short period of time and reducing the immersive experience can help.
Apple says that to reduce motion sickness, users should reduce head movements and move their head and neck as little as possible. Apple also recommends reducing visual motion by reducing window size, reducing immersion, and turning on the "Reduce Motion" setting in the Accessibility section of Settings.
People who suffer from motion sickness should also avoid high-motion experiences like Apple's Immersive Media, as well as spatial videos with a lot of motion.
