    The execution is carried out with the investigation of legal regulations that authorize the design and construction of eye protectors and that is legally permitted in Ecuador, this being the official registry RTE INEN 216, which cites the standard EN 166: 2001 as reference for the design and construction of eye protectors. In accordance with the beneficiary company, a design for "glasses with lateral protection" is established and focuses on optimizing conventional designs under the concept of less, moreover, providing greater protection of the eye area proposed by the standard mentioned with a product of three elements that are assembled by adjustment and without metallic pins. The final geometry was obtained after several designs that were captured in prototypes by means of molten deposition molding (3D printing) and served as a guide to visualize constructive details. Once the 3D geometry was established, the CAD design of the matrix for injection molding was carried out, where the parameters of the injection machines were used for the design of two injection molds, injection pressure parameters, closing force, and injection capacity define the geometry of the mold and number of cavities. Each element of the injection molds was built, with a manufacturing process by chip removal that allows obtaining each mechanized element. To then be assembled piece by piece and then mounted on the injection machine, where injection tests were carried out until the desired product was obtained.
