If you are writing or studying,it makes wery much difference where the light comes from ,People who use books and pens every day have to be specially careful about the way the light shines on their page .
Every house gets its light either from daylight through windows which is the very best to use or from the lamps or electricity , but whichever kind of light it is ,the way it slants towards our books or our works is a matter of great importance to the eyes .
Take a book ,stand with your back towards the window ,and try to read ,your shadow 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 lightis in your eyes.
Try standing with your right side towards the window.This is very good for reading ,but if you were writing, the shadow would fall across the page and bother you a little .
There is just one other way:sit with your left side to the window.Now everything is perfect 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.
