Cybersickness is a jokey name for feeling unwell because you have been on a computer too long, or you have sat in a room full of screens and machines. People say it when their eyes hurt, their head feels heavy, or they feel a bit sick after hours of clicking. In this use it is not a doctor's word; it copies words like seasickness and is meant to make a colleague smile. You would hear it in a casual chat, not on a hospital form. Though actually, some people also use it for the dizzy, car-sick feeling a virtual-reality headset can give. That use is more serious. The learner-dictionary sense is the humorous office one.

沒有很固定的病名；開玩笑時多半說「電腦坐太久不舒服」或「電腦暈」。若是戴 VR 頭暈，台灣較常說「暈動症」，不要把它當成正式診斷。
