FAQ 
What is the magnet parts for? Do I need it? 
The magnet can trigger the "click" event in Google Cardboard App (more and more apps support magnet now) so you can control your smartphone easily. If there is no magnet parts you have to take the smartphone out, touch the screen then put your smartphone in, again and again.... 
I wear glasses, how to adjust the lens focus to suit my eye? 
Rotate the lens parts, you can adjust it. If you are nearsighted more than 400 degrees, please rotate the lenses out then rotate it in from the other side. 
What screen resolution I need? 
If your phone screen resolution is under 720p, you cannot get very good experience. We suggest 1080p screen. 2K screen will be the best. 
Can I watch standard 2D movies / play 2D games on it? 
Sorry, this goggles designed for 3D only, it cannot support normal 2D resources.
