My brother had this headset. he is using for four months. but after using this vr headset his eye sight power decreases. he told about this vr headset to doctor. the doctor told him not to wear this headset as there may be chance to get loose eye sight power. now he stops wearing the headset. any vr headset may cause to damage your eyes so plzzz minimize the use of these vr headset. I do not want any other to suffer like my brother. prevention is better than cure.
