Abstract

In investigations of the eye blink reflex it was found that there exists a dependence on the wavelength of the applied laser device considering the frequency of this physiological reaction. The experimentally acquired correlation shows a much weaker association with the V(λ)-curve than it is normally valid for photobic vision. The experimentally obtained results might be explained by the well-known fundamental WEBER-FECHNER-law of psychophysics and will be given as a blink reflex function in accordance with the STEVENS power law. The results of 788 measurements at 670 nm, 635 nm and 532 nm in lab and field trials in which the head of the tested volunteers was fixed on a chin rest were confirmed in two additionally performed studies with 516 volunteers with an unrestrained head in which either a direct intrabeam viewing or an eye-tracking method was applied in order to simulate typical irradiation situations.
