This specification covers eye protectors, designed for use by players of racket sports, women's lacrosse, field hockey, basketball, baseball, and soccer that minimize or significantly reduce injury to the eye and adnexa due to impact and penetration by racket-sport rackets and balls, women's lacrosse and field hockey sticks and balls, baseballs, soccer balls, hands, elbows, and fingers. Protective eyewear offers protection only to the eyes and does not protect other parts of the head. Protectors are divided into four types depending on their design characteristics as follows: Type I—A protector with the lens or lenses and frame frontpiece molded as one unit. Frame temples or other devices, such as straps, to affix the lens/frontpiece may be separate pieces; Type II—A protector with a single lens or lenses, either plano or prescription, mounted in a frame that was manufactured as a separate unit; Type III—A protector without a lens; and Type IV—A full or partial face shield. Materials shall be tested using optical tests such as field of view, optical quality, luminous transmittance, prismatic deviation measurements, haze, refractive power measurements, surface imperfections and internal defects, and alternate optical tests; and mechanical tests such as high velocity impact resistance, and projectile simulator test. In addition, the individual grades shall conform to the general, and performance requirements.
