With the DJI Googles Integra, there are 11 (Pair) corrective lenses included. From -8D, -7D, -6D, ... to +1D, +2D.
If your correction is one of these numbers, put the right lenses into the googles and you are good to go. Otherwise, if like me you are outside this range (I need +3,5D) then you need to order custom prescription lenses or use contact lenses like I do, works perfectly.
With the DJI Googles 2, you can adjust manually the correction, so I guess you can have -6,5D for exemple, but the range is also limited from -8D to +2D. If you are outside this range, the only solution is contact lenses.
