I spent an hour or two on Shandong Normal University campus in Jinan and noticed an interesting addition to the services available at their university library.
The sign on the left reads:
Library Glasses Department (in red)
Accurate Eye Examination, Fast Delivery of Glasses (in blue)
Similar info on the vertical sign.
That the library would have its own optical department may be attributed to the fact that lights are often not bright enough (In Jinan metropolitan museum the day before I could barely see the paintings hung inside the exhibition room it was so dark) but it could be that the heavy reading loads the young students of Beijing Normal University must face make this a conveniently accessible service. Come to think of it, perhaps every large university library should consider this strategic addition?
