HMD with minimum IPD ( Interpupillary distance)

I need a vr headset for kids. IPD should be around 53 mm. Do you know any headset with that dimension? It can be a cardboard, MR, standalone.

I have a pretty narrow ipd myself (57.5 mm). Lowest IPD settings (when available) are 59 most of the time. Standard adult IPD is around 65 i guess.
I would go for a custom VR cardboard with a small phone screen, but i’ve seen ten years old kids try 59 mm ipd setting VR without noticable visual discomfort on short sessions.
However, at the risk of going off-topic, i would like to remind about the health concerns of exposing a young kid to VR, because business goes crazy real fast with new technologies. So i’m fine with the actual limitations even if sadly they are actually technical rather than ethic.

Edit : Sorry to insist, but after posting i still feel concerned about that subject. I would personally NOT go for a custom ipd VR cardboard, but that’s my technical answer. @atmuc i don’t know your plans behind the question, that’s just worrying to me. I’ll stop here as it is not the topic.

@Gruguir i will use it for an eye treatment. I work with a doctor.

Good to know, i guess you should have notified that first ^^'. I think that would really require custom solution.
