For consumer electronics - (in order of importance)
1) Industrial design (thin, flat, light – forgettable glasses)
2) Costs (all optics have to be easily mass replicable)
3) Power consumption < 10mW
4) Peripheral vision not affected
5) Eye box >10x10mm
6) Eye relief: between 19mm and 21mm
7) Resolution: > QVGA
8) Transparency: >50%
9) FOV >= 20 degrees
10) Contrast: > 50:1
11) Field distortion <5 % and MTF (@40 lines/mm): 0.3
12) Full color operation
For defense applications – HMD type – (in order of importance)
1) FOV >= 60 degrees
2) Eye box: > 14x14mm
3) Eye relief: 30-32mm
4) Environmental stability
5) Resolution: >= UWVGA
6) Field distortion: < 0.5% - MTF (@60 lines / mm): 0.6
7) Contrast: >200:1
8) Single color operation
9) Transparency: >90%
