Make sure the glasses have very large lenses. Each lens will become an eye on your mask, so take some reference pictures of Spiderman with you when you go shopping. Look in the women’s sunglasses section, as many women’s styles feature larger lenses.
Look at photos of Spiderman as a reference to get an idea of the shape of the eyes. In most incarnations of Spiderman, his eyes are roughly triangular, with a straight line on top and a U-shaped line forming the lower eyelid.
Apply the second lens. Using the exact same method, glue a thin line to the other lens and then affix it to the inside of the mask, creating the second eye. If you place the lens incorrectly at first, you will have a few seconds to move it before the glue dries. Apply light pressure to the side of the lens to fill the eye-hole while the glue is still hot. The glue will take around 15 seconds to set, so keep in mind the amount of time you have left to make changes.
