The glasses on the glasses creates the bespectacled 3D viewer odt an uncomfortable friction and like slipping even the lenses against each other, which can lead to headaches after prolonged period film also. Ideally, two placer offered in this box, which are very easily attached to the existing spectacle frame, hold very well and offer a significantly higher comfort. I am absolutely delighted and would not want to miss the Aufsteckvariante, yes I have even mitgneommen the movies. My recommendation for all who wear glasses (no shutter technique need).
