Using these goggles is easy. Just put them on over your regular glasses, making sure they sit comfortably on your face. If you want to use a neck strap, simply thread it through the holes in the arms. When it comes to maintenance, clean the goggles with a soft, damp cloth. Avoid using harsh chemicals as they may damage the clear surface. Also, store them in a cool, dry place when not in use. Be careful not to scratch the goggles, as this can affect your vision. And remember, these goggles are for general eye protection, so don't use them in extremely hazardous situations without proper consultation.
