I think no one has complained eyestrain with this unit but it could be that it's too heavy to wear long time
.I think these force you to focus quite long distance so if you are nearsighted and need glasses you need to use them with this set too. So if there is no eyestrain with 3D projector then i think it's safe to assume it no issue here either and with 2 oled's there is also no ghosting or flickering. I think biggest issue is weight and lack of comfort for long runs. I'm soon to find out how it all work, too bad there is no 3D for CoD at the moment so 3D flight testing i'm using RoF.
