nearsighted: google Cardboard: Which lenses? f?
I am nearsighted and my right lens of my glasses has -6.0 spheres. My left lens of my glasses has -6.5 spheres.
I have tried the standard cardboard with convex lenses with focal length f=45mm.
If I use the cardboard with this lens without glasses, then the image is blurred. With glasses it is sharp.
Question: Is there a way to find out with which lens I would be able to use the cardboard without glasses and at what distance I do have to place the smartphone from the lenses?
Would appreciate a helpful answer. Thank you.
