i have a box type goggle and used it with no problem
However I tried upgrading to a lower profile goggle, so i chose the Aomway commander V1

it works pretty well, but I keep getting double/ duplicate image in my head, and that's pretty annoying

I have far sight, which is +3.5 and +5, however i can use VR headset with no problem
and my pupil distance is 68mm, which i measured the goggle and it gave enough room for my eyes

the image overlap a little bit in the middle, i tried focus and can only make them further away (not close into one image)

Then I tried to make Diopter with glasses found in Dollar shop. The image got clearer, however I still got overlap images

Did i missed something or goggles just don't fit me

thanks in advance

There are companies that make custom diopters using you optometrist's prescription. Here's a link
