ABSTRACT:
This invention refers to an auxiliary lenses unit for glasses, for example colored lenses, to superpose on the generally graduated lenses of a normal pair of glasses. Said unit includes a central body on which a pair of auxiliary lenses hang, by means of a suitable bridge member which can rotate in respect of said central body; this central body is provided with two pairs of pincers, to fix the auxiliary lenses unit to the glasses, whose opening is operated by an element which is integral with one of the two extensions forming each pair of pincers and which acts on it in such a way as to cause, by a manual push, the opening of the pincers owing to the elasticity of the material the above-mentioned central body is made of.
