This only suggests the glare from surface area from the drinking water or the street or the motor vehicle lid will be powerful. Polarized sun eyeglasses have a very laminated surface containing vertical stripes. These stripes only allow vertically polarized mild to enter the wearer's eyes. Glare is deleted because the horizontally polarized mild wave can not go within the polarized filter.
