GLASSES WITH LENS SET INTERCHANGEABLE TO THE VARIATION OF THE SUBJECTIVE STATUS CAUSED BY VISUAL TIREDNESS

摘要

Device for the correction of accommodative visual defects linked to the extended exposition of workers to the luminous irradiation of display terminals, of televisions as well as to reduce the asthenopia due to excessive visual efforts in the artisan, industrial and free-time activities. The glasses help considerably the forced accommodation work of the eye, reducing all consequences deriving from extended visual efforts in the working activities, by means of the variable (from sphere -0,75 to sphere +0,75) and interchangeable lens set at the moment of slight variations of the subjective visual status of the worker. The glasses are realized with four reinforced rubber gaskets, arranged on the internal side of the frame so as to realize a vertical holding of the lens placed in order through the simple pressure of the fingers of the hand.
