The blinders or black out that you see when jumping/moving/turning in VR are due to having comfort settings on.
If you'd like to remove these behaviors, please do the following: Open your watch, go to settings, go to the gameplay tab, and click "Comfort Options".
Please uncheck some or all of the buttons, depending on your preferences.
To remove the blackout that happens when jumping/falling, please change "Comfort Mode" to "Off"
There are many more settings on this page to mess around with, so please experiment and find a combination of settings that are right for you. If you don't experience motion sickness in VR at all, you're welcome to turn all settings off for a blinder-free experience.
