Using these costume goggles is easy. First, decide if you want to wear them on your head or over your eyes. You can combine them with NeoPixel rings as shown in our tutorials. When you're putting electronics inside, use the dark - tint lens to hide them. If you feel uncomfortable, add some foam padding. Remember, these goggles are only for costumes, so don't use them in activities like welding or flying. To maintain them, keep them away from sharp objects to avoid scratches on the lenses. If they get dirty, gently wipe them with a soft cloth.
