Goggles typically consist of a frame that holds lenses securely in place, with adjustable straps or arms to ensure a snug and comfortable fit. The frame material varies, ranging from durable plastics to lightweight metals, depending on the intended use and level of protection required. The lenses may be made from polycarbonate, acrylic, or other impact-resistant materials, often treated for scratch resistance and anti-fog properties. Some goggles feature foam padding around the edges to provide a secure seal against the face, blocking out debris, dust, and liquids.
