GOOD HEALTH 



the evening, or a shade over the lamp, will keep the light 

 out of our eyes and throw it on our work where we need it. 

 Yet there is the opposite danger of too little light. 

 Thousands of women ruin their eyes by sewing in rooms 

 that are too dark, while thousands of both men and 



women injure their sight by 

 reading in the twilight or by 

 dim lamps. It is not safe to 

 do these things. Eyes are too 

 precious to be strained either 

 by too much or too little light. 

 After all, however, the great- 

 est danger to children's eyes is 

 from microbes. Indeed, 

 some of these microbes 

 can do as much harm 

 I as a Fourth of July 

 explosion. 



Several years ago, in 

 a city of Germany, 

 there was a great epi- 

 demic of eye disease. 

 The first anybody knew about it was that thirteen 

 children in one schoolroom had the trouble. Then it 

 went from room to room and from schoolhouse to 

 schoolhouse until four thousand children were suffering 

 in that one city alone.
