Different glasses will have different mileage depending on the size of the frames and thickness of the prescription lenses. We cannot guarantee that the interface will fit your glasses. 


To allow more room before the display so that your glasses do not bump up against the lens, try using the original Quest 2 glasses spacer that came with the headset or the VR Cover XL Spacer for Meta Quest 2


Be aware that using a spacer will potentially cause light to leak through the passive air vents. 


If you have prescription frames that are wider than normal, position the foam on the interface as far as possible from the center. This helps to open up the gap to fit your glasses inside more comfortably.
