Abstract: The invention relates to industrial safety goggles provided with permanent ophthalmic micas having a full impact protection mica positioned thereon, wherein said impact protection mica is made from polycarbonate, provides protection against ultraviolet rays and can be removed, thereby enabling the frames to be used as ophthalmic glasses. Said goggles include a ventilation area and the ophthalmic micas have an improved visual field owing to the design of the frame to which they are mounted and fixed using angular incisions in the frame. The frame is provided with an open space at both eyes between the mica and the end of the rim, which provides ventilation and prevents the fogging of the graduated micas. The sidepieces of the goggles are designed to curve at the ends thereof, so that the goggles can be put in place without the user having to remove his/her industrial safety helmet.
