Retinal movement (light and dark adaptation) and the effect of ultraviolet radiation in it and histological structure in two teleost species fishes [PDF]
the rctinomotor movement (light & dark adaptation) of two teleosispecios : Chalccilburmisinossufansisand Noemctcheihi§ angora, have been studied. The adaptation carried out in a photoperiod of 12: 12 hrs dark : light. Under visible light intensity of 700

Ultraviolet Light Protection: Is It Really Enough?
Our current understanding of the pathogenesis of skin aging includes the role of ultraviolet light, visible light, infrared, pollution, cigarette smoke and other environmental exposures. The mechanism of action common to these exposures is the disruption
