The invention relates to a pair of googles which comprise a frame with two rims in which an optical unit is respectively intended for being assembled via a reversible attachment device in order to provide an inner attachment of said optical unit in said rim, each device comprising a button and a cavity rigidly connected to an outer edge of the optical unit and the rim, respectively, said button being capable of being inserted into said cavity in order to provide external locking of the optical unit in the rim, each rim having one recess opening onto the rear, each optical unit having a front bearing surface which, in the assembled state, is arranged against a rear complementary bearing surface of said recess, at least one of the outer edges being reversibly deformable to allow the placement and the withdrawal of said button in said cavity when the bearing surfaces are arranged against one another.
