Hello guys
I want to make my own HMD smaller.
To achieve it, i should make Focal lenght less than 40mm.
I tried 25mm Focal length with 6" display and it seems fine, coz i can see everything on display, no cutting.
So, is there any formula or rule that it should be not less than 40mm?
Thanks
Why focal length is should be 40 mm?

It is difficult for most people to focus their eyes with lengths < 40mm.
