Super-wide-angle double-lens intercalated eyeglass: the 280°wide-angle lens meets all optic factors, through which you have a broad and clear visual field. Since a special water-unabsorbable sponge is set around the center between inside and outside layer, the center is hollow. Thus no water will be absorbed to form fogs. Moreover, the bending angle of both inside and outside eyeglass is the same, meeting all optical conditions.
Therefore, no refraction or deformation will appear when wearers take a look at an object.
