The problem is that even reading glasses won't fix the problem as the screen is too large for the optics so you can't see the entire screen with each eye. This results in a non-sharp image which strains your eyes to see certain parts of the screen. For example, the flight information in the lower left corner. Cover one eye and read a book, you'll realize how much you need both eyes to see and how stressful it is to only see through one eye. This is how the
goggles are for parts of the screen.
Also, instead of just having one screen with both eyes looking at it, they decided to use two screens with a complex mirror and polarized system so each eye would see two different screens. Why? Good question! If it was VR and it was 3D vision it would make sense. But, both screens display the same image so it makes zero sense why they did this. Far more expensive and I believe the optics problems are the direct result of this terrible design decision.
Finally, they're not designed for someone with 20/20 vision. The options are designed for someone who has myopia. If you have good vision, you'll have a problem seeing the screen because DJI screwed up the lenses. Some have suggested this is because something like 90% of Chinese have myopia and need corrective lenses to see at a distance. So, it's very possible that they designed the
goggles for people with myopia and the result is those with excellent vision can't see the screen clearly.
In all, it's a huge design problem and a total fail for the
goggles. As a result, they're about worthless.
