A Chinese business man (Xu!) argued with his wife. To blow off some steam Xu went to a local cyber cafe and decided to play some online games. He went four days without sleep, and was staring at screens for over 90% of the time.
He went to the doctor after his vision started to dim, and was diagnosed with temporary blindness because of eye strain due to 96 hours of gaming. Xu’s age was not disclosed. His vision was fully recovered, and I’m sure the doctor told him to stop staring at screens for so long.
The lesson here, Geeklings, is to rest your eyes during long-term gaming sessions. This can be avoided.
