Excerpt from The Pathological Effects of Radiant Energy on the Eye: An Experimental Investigation The fundamental purpose of this investigation has been to dis cover what if any pathological effects can be produced upon the structure of the eye by exposure to artificial or natural sources of light. That such action may occur under sufficiently powerful exposure to radiant energy is certain, but the essential fact is the discovery of the quantitative relations between the amount Of incident energy and the effects. These relations have generally been left quite out of the reckoning in discussing the subject, with the result of leading to vague and Often quite unwarranted conclusions as irrelevant as if one should condemn steam heating as dangerous because one can burn his finger upon a radiator. The quantitative phase of the matter is, from a practical standpoint, all-important since on it depends the actual effects to be expected from the exposure Of the eye to powerful natural or artificial sources of light. Although the literature Of the subject is very extensive, the appended bibliography covering over 450' titles, practically none of the work done has been quantitative in the sense of connecting the amount and kind of the energy received with the effects produced, and hence, despite the work Of many careful investigators, the results have been singularly discordant and inconclusive, so that a co'o'rdi nation Of the facts from the standpoint of energy has seemed impera tive. One of us 19 has investigated recently the energy relations of the radiation from various sources of light both natural and arti ficial, and the intent of the present investigation has been to determine by actual experiment on the eye the quantitative and qualitative effects of radiant energy on the conjunctiva, cornea, iris, lens, and retina.
