Quick instructions on how to make cheap glasses by type this https://www.bestadvisor.com/steampunk-goggles
Prepare the base
Buy welding glasses. Welding goggles are of two types: they look like swimming goggles or like diving goggles (or goggles). Any option will do. It should be understood that glasses with two bowls and a short band on the nose (as swimming) will have a more authentic look.
Disassemble the glasses into details. Remove all available straps, including the bridge of the nose straps, and then squeeze the glass and remove the protective visors. Do not forget about the other parts like rubber bands and linings.
Unscrew the clips that hold the glass.
If you can not remove the glass, then seal them with masking tape.
Apply 2–3 thin layers of paint to the glasses frame. It is necessary to work in a well-ventilated area, and even better outside. Buy a paint can of brass, copper, bronze or dark gold. Apply the next layer only after the previous one dries. Much depends on the brand of paint, but usually it dries in 20 minutes.
It is better to apply several thin layers of paint than one thick layer. In the latter case, the paint may dry out unevenly and the result will be a soft and sticky finish for your glasses.
If there are buckles on the straps, they can be painted in the color of the frame.
If the glass is attached using clamps, they can be painted in a lighter color for contrast (light gold or silver).
Wait until the paint is completely dry. If the paint feels dry to the touch, this does not mean that it has dried completely and the glasses are ready for use. The exact time can be found on the can of paint. If you hurry, then the paint may appear dents and scratches.
Make light and dark areas. To do this, you need a dry brush and acrylic paint or polishing paste. Apply light paint on the protruding areas, and dark paint - on the cracks and grooves. After this, the glasses should be completely dry.
For light areas, a lighter shade of paint like pale gold will be required.
For the shadows, use a dark dye of dark copper, brown or black
Collect points, but without straps. The straps will be homemade, so now you need to insert the glass in the frame. If the glass was painting tape, then it should be unglued.
