REMOVAL OF CINDERS 265 



doing fine work and reading in bad light. If the eyes 

 pain, use a cloth heated with very hot water. A two per 

 cent boracic acid solution is an excellent wash, and may 

 be used frequently. This, or a salt solution made of one 

 teaspoonful of salt to a pint of boiling water, may be used 

 to wash the eye after getting a cinder in it. 



Removal of cinders. Sometimes particles of dust 

 or cinders get into the eye. These are usually washed 

 out by tears which flow as a result of the irritation. Some- 

 times, however, they have to be removed. In the case 

 of the lower lid, there is little trouble ; if one pulls the lid 

 down the speck can easily be removed with the use of a 

 clean handkerchief. The upper lid is more difficult to 

 pull back. In order to do this successfully, have the 

 person look downward, place a 

 small pencil against the upper 

 portion of the lid, take hold of 

 the eyelashes, turn the lid up- 

 ward and back over the pencil, 



and the lid is in such a position Turnin * the ^ back to remove 

 that the speck can easily be lo- 

 cated. Sometimes a tiny sharp-pointed bit of glass or cinder 

 becomes embedded in the surface of the cornea. A drop of 

 olive oil in the eye prevent* irritation until with the help of 

 an expert physician it can be removed.
