To the Editor:—
In the New York Navy Yard, where 70,000 civilians were employed, 52,704 injuries were reported in 1944. Of these, 11,380, or 21 per cent, were accidents to the eye, predominantly caused by the presence of foreign bodies.While the foreign bodies in the conjunctiva were readily removed without loss of time on the part of the employees, those in the cornea, particularly the metallic bodies with a circumscribed rust ring, were not as easily taken out and usually gave rise to absenteeism. These lost man hours were due chiefly to the fact that the eye was covered after removal of the particle, with a consequent loss of binocular vision. As this incurred an added hazard to an already hazardous job, the patients frequently were permitted to go home or were transferred temporarily to an unskilled nonhazardous position. Ocular pain, too, was a definite contributing cause of time
