If you are writing or studying, it makes very much difference where the light comes from. People who use books and pens every day have to be especially careful about the way the light shines on their work.
Every house gets its light either from daylight through the windows—which is the very best to use—or from lamps or electricity (电器); but whichever kind of light it is, the way it shines towards our books or work is a matter of great importance to the eyes.
Take a book, sit with your back towards the window, and try to read. Your shadow (影子) falls all over the page and makes it almost as bad for your eyes as if you were in a dark room.
Now turn around and face the window. The page is in the shadow again, while the bright light is in your eyes.
Try sitting with your right side towards the window. This is very good for reading, but if you were writing, the shadow of your hand would fall across the page and bother (烦扰) you a little.
There is just one other way: sit with your left side to the window. Now everything is good for reading and for writing, too.
Whatever kind of light is in the room, the rule about the right to sit is always the same.
