Final answer:
Safety glasses, goggles, and welding shields are all forms of personal protective equipment for eye protection, offering varying degrees of UV and radiation shielding, with full coverage recommended.
Step-by-step explanation:
Safety glasses, goggles, and welding shields are all considered forms of personal protective equipment (PPE) for the eyes. Protective eyewear is essential for individuals working in environments where they are exposed to hazards such as ultraviolet radiation, intense light, or flying particles. Full coverage eye protection is recommended to prevent light from reaching the eyes from the sides. While ordinary glasses provide some protection, most plastic lenses, especially materials like polycarbonate, offer better protection by blocking most UV radiation. Specialized equipment such as welding shields also protect the eyes from high-energy radiation that could otherwise cause severe retina damage.
