The term GOGGLES PART can be solved with the word LENS, which is a four letter word. A LENS is a curved piece of transparent material, usually glass or plastic, that is used to refract light and form an image. Lenses are commonly used in eyeglasses, cameras, and other optical instruments. Goggles are a type of protective eyewear that are designed to cover the eyes and provide protection from dust, debris, and other hazards. The LENS is an essential part of goggles, as it helps to protect the eyes while allowing the wearer to see clearly.
