摘要

Improvements introduced in the glasses conceived for mixed vision possibilities, comprising an armature in which, for each eye, two lenses are incorporated, one for near vision and another for remote vision, characterized in that a horizontal dividing line is established between the lenses for close and remote view in each of the hoops, being such a line unique, having on it a thin material axis for the rotation of inserts susceptible to prevent, alone or in conjunction with the optical lenses themselves, completely the passage of light through the totality of one or another of the near vision or remote viewing areas.
