ABSTRACT:
Sunglasses and other light transmitters for human viewing and illumination are characterized by an efficient transmission of photobiologically-active radiations, thereby offering the users (especially sunglass wearers) a physiologically-oriented alternative. Furthermore, the .lambda.max and the peak absorbance wavelengths of human rhodopsin exemplify those wavelengths which must be transmitted, since they are photobiologically impeccable. Tinted photobiologic sunglass lenses transmit a light spectrum (FIG. 1) exactly within the human rhodopsin absorption curve (FIG. 2); they also provide antiglare as well as ultraviolet and infrared protection by attenuating radiations outside the photobiologic spectrum. Photobiologic sunglasses are also ecologically beneficial, restoring in part the pristine quality of the albedo which has been adulterated by modern urban enviroment. Specific photobiologic coatings provide various substrates with antireflection characteristics resulting in improved photobiologic transmission, and energy-saving infrared rejection. Tinting and coating are photobiologically cumulative. By transmitting the light which is most biologically active, photobiologic sunglasses and transmitters offer multiple health advantages over most prior-art sunglasses which interfere with photobiologic light and, consequently, have been reported to represent a significant health hazard. Therefore, photobiologic sunglasses and transmitters can help prevent some forms of mental depression (and the related increased suicide tendencies), a loss of fertility, as well as libido impairment, all caused by inadequate photostimulation. Maintenance of unperturbed mental and physical skills, of normal sleep, and of undisturbed metabolic functions, help maintain the well-being of photobiologically-stimulated sunglass wearers, and of photobiologic transmitter users.
