Just to add as is shown in @jorgearq image a tethered headset allows for you to see on the laptop screen where the VR user is in the scene. Whilst this is technically possible by streaming from a Quest to a phone or Google Chromecast, we have had limited success using these methods.
ps @jorgearq the Quest Resolution is really good. Sure there are VR geeks who will have an opinion on the specs and compare to other tethered experiences, but we have found the quest comparable to the Vive Pro and Rift S in terms of quality and for a casual or new VR user I would suspect they would be absolutely blown away by it.
@Vladan Ref Glasses & VR Headsets it really depends on the physical size of your glasses. In our experience the Vive Pro and Rift S have the most space and adjustment for Glasses with the Quest & Vive less so although the IPD adjustment on Quest is simpler, (This may be part of the blurry issue you have)
