National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Ocular Ultraviolet Effects from 295nm to 335nm in the Rabbit Eye.


PB274880

Publication Date 1976
Page Count 62
Abstract Pigmented rabbit eyes are exposed to 6.6 nanometer band-pass ultraviolet radiant energy in 5 nanometer steps from 295 to 320 nanometers and at random intervals above 320. Corneal and lenticular damage is assessed and classified. Corneal threshold radiant exposure rises rapidly from 0.022 joules per square centimeter at 300 nanometers to 10.99 joules per square centimeter at 335 nanometers. Radiant exposure exceeding two times the corneal threshold radiant exposure result in irreversible corneal damage. Lenticular damage is limited to wavebands above 295 nanometers. There is an action spectrum for the lens which begins at 295 nanometers and extends to about 315 nanometers. Permanent lenticular damage occur at radiant exposure levels approximately twice the threshold for lenticular radiant exposure.
