A lens structure including a quarter wave plate layer and a linear polarizing plate layer is provided. When the linear polarizing plate layer is located at an outer side of the lens away from a viewer's eye, the polarizing axis of the linear polarizing plate layer is in a vertical direction. The lens structure can be used to make dual-purpose eyeglasses with sunglasses and 3D glasses functions. Any one of the quarter wave plate layer and the linear polarizing plate layer can be disposed at the outer side away from the user's eyes by adjusting the orientation of the lens of the present invention. When the linear polarizing plate layer is located at the outer side away from the user's eyes, the optical axis of the linear polarizing plate layer is in the vertical direction. Thus, the dual-purpose eyeglasses with both sunglasses and 3D glasses functions can be achieved.
A lens structure characterized in that:
A pair of dual-purpose eyeglasses with sunglasses and 3D glasses functions, comprising an eyeglass frame, and lenses and two temples mounted to the eyeglass frame, characterized in that each lens comprises a quarter wave plate layer and a linear polarizing plate layer, and the lens has two outer surfaces which are respectively and simultaneously defined by one surface of the quarter wave plate layer and one surface of the linear polarizing plate layer, the lenses and the two temples being pivotable relative to each other to allow the location of the quarter wave plate layer and the location of the linear polarizing plate layer being exchangeable between an outer side of the lens away from a viewer's eye and an inner side adjacent to the eye;
A pair of dual-purpose eyeglasses with sunglasses and 3D glasses functions, characterized in that the dual-purpose eyeglasses comprise a lens and a clamp, the lens comprises a quarter wave plate layer and a linear polarizing plate layer, a polarizing axis of the linear polarizing plate layer is in a vertical direction, and the lens has two outer surfaces which are respectively and simultaneously defined by one surface of the quarter wave plate layer and one surface of the linear polarizing plate layer, the clamp comprises a first clamping portion for clamping the lens and a second clamping portion for clamping another pair of eyeglasses;
