Abstract

The use of laser light in biostimulation studies raises the issue of the uniqueness of laser light. Are such effects related to the qualities unique to laser light or a manifestation of photic exposure effects on biological systems in general? In this paper, we have reviewed studies in the ocular low level light exposure effects area. Several papers suggest a unique role for coherent stimulation regarding low level light effects on vision. Long term deficits in visual function may result from either large discrepancies in peak to average power, neural fatigue from unique neural stimulation, stimulation of basic energy sensitive biochemical neural systems. These effects have implications for biostimulation investigations and could underlie the effectiveness of low level long wavelength coherent light exposure.
