Special lenses and glasses fitted with them have polarization angle adapted to individual users. The angle of astigmatism of the user is measured. If this angle is in the range 0-90 deg., a polarizer with an angle that is 90 deg. greater than the angle of astigmatism is adhered to the side of the lenses that is further from the user's eyes. If the angle of astigmatism is over 90 deg. and up to 180 deg., the polarizer used has an angle that is 90 deg. less than the angle of astigmatism.
