Health issues with prolonged use of the Microsoft HoloLens 2 While the HoloLens 2 is marketed as a great tool for workplaces and for personal usage, users must be wary of the possible heath issues associated with prolonged usage of the device. Such issues include dizziness, discomfort, and dissociation from the real world (National Library of Medicine, 2018). Eye strain can also be a major factor as the user will be exposed to a screen interface for extended periods of time. Head strain with the tightening of the head strap has also been observed to be a major issue. Most users also claimed a dissociation from reality as, after a simple 90 minutes of usage, becoming acclimated to the real world proved to be a strange experience (The National Library of Medicine, 2018). As such, it is recommended to use the device is short hour-long periods to reduce any possible health issues. Reference - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6225835/
