I give you a star deduction as well unfortunately a little mistake at the manufacturer has happened: on the (over) box the manufacturer is the 'right' name on it, but in a package in which glasses was unfortunately without the calibration lines are / were. That's a shame but really (at least for me) not quite as bad. Am much more pleased that the glasses (also) so ne good quality (ie at first glance not a cheap product) completely and all;. P
