Going to the theater to take in a 3D movie is still, at this point, a novelty. But as more and more blockbusters get released in 3D and 3D-capable home televisions become increasingly popular, we’re predicting that the day when we can cue up the latest 3D feature on Netflix is just around the corner. Magic Eye illusions were some of the first 3D effects we remember from our childhood, and since then we’ve seen entire magazine spreads in 3D imagery like last summer’s issue of Time Out New York.

For those occasions when you stumble upon a 3D relic, you either have to squint, cross your eyes, or (if you’re lucky) use those flimsy cardboard 3D glasses that disintegrate after one use. At most theaters you’re required to recycle 3D glasses once the picture is over, so this Instructables How-To will teach you how to make 3D glasses of your very own that you can whip out whenever the occasion strikes… and believe us, there will be plenty of those to come.

For this project, you’ll need two circular polarized lenses, two lens adapter rings, one pair of “Gaga-esque” round glasses frames (to accommodate the shape of the lens), some metal/plastic adhesive, boiling water, and a small jeweler’s screwdriver.

First, carefully remove the arms of the glasses and set aside with the screws. Then soak the modified frames in a pot of boiling water to loosen the lenses. When they are soft enough, use the flat blade of the screwdriver to start prying the lenses out of the frames. Then re-soak until you’re able to completely remove the lenses. This step may take some time and patience.

Dry the frames and glue the adapter rings onto the frames, aligning the labels at the top for an added touch. After the glue has dried, re-attach the arms, screw in your filters, and experiment with a variety of lenses for different effects!
