Women tend to suffer from motion sickness more than men when using virtual reality headsets. This study suggests that the main reason why is simply that the headsets are not well designed for people who have the sorts of distances between their pupils that females are more likely to have; their interpupillary distance.

Seems even the devices of the sci-fi future continue to be designed in sexist ways. Famously, Caroline Criado-Perez’s book Invisible Women has a ton of further examples.
