Head mounted displays (HMD) are in widespread use for virtual environment applications and they are the focus of many discussions in ergonomics. Most of the HMDs coming onto the market without any proven ergonomic aspects and this in times of pan-European regulations for display working places. Many tests have been done in the field of ergonomic aspects of HMDs, therefore, we saw this as an opportunity to delve deeper into the possibilities these display devices give us. This paper introduces technical aspects of head mounted displays and pertinent health concerns. It will help to show the possible ways of testing the ergonomic quality of these devices and permit comparisons to be made. In addition to the fundamental description there are also results from experiments that have been conducted with different HMDs and with many skilled and unskilled users. Some of the experiments made are listed below: Comfort, learning curve, flicker fusion threshold, electroencephalogram andelectrocar diogram of the user, concentration test and coordination test, subjective fatigue and questionnaires. Future projects in this field of studies and a list of HMD values conclude this work.
