Goggles are basically glasses that strap on to your head and cover your whole eye area. Swim goggles and safety goggles protect your eyes, but there’s also virtual reality or night vision goggles that enhance or change what you see.
Usually, goggles are protective eyewear. There are goggles you wear when riding a motorcycle, working in a lab with chemicals, or playing sports, for example. Some goggles do more than protect your eyes — night vision goggles help you see in the dark, and virtual reality goggles make it look like you’re in another world. The word goggles, first used around 1715, comes from goggle and its Middle English root gogelen, "to roll the eyes about."
