Abstract

In connection with an extensive campaign for the protection of the eyes of workers from injurious radiation, especially those workers in the Government Service, the Federal Specifications for eye-protective glasses have recently undergone a revision.

The present paper gives technical data proposed to and adopted by the Technical Committee appointed to write these specifications.

The new specifications permit a continuous gradation of shades, without loss of material which is advantageous to both the producer and the consumer. The adoption of a fixed scale of densities gives assurance of uniformity of production and labeling that cannot be changed at the whim of a manufacturer or user of eye-protective glasses.
