Glass etching product
Eyeglass lenses are protected by anti-scratch and anti-reflective coatings. If the coatings become scratched or damaged, the blemishes can easily interfere with your line of vision. One solution is to remove the coating, as this will remove the scratches while leaving the plastic lens intact and undamaged. Commercial glass-etching products are readily available and easy to use.
Clean the lens with a glass cleaner. Remove smudges, fingerprints and other contaminants on the lens. Dry the lens with a microfiber towel.
Apply a glass etching product evenly to both sides of the lens. Let the product stay on the lens for several minutes. Glass etching products are available at hobby stores, craft stores and home supply retailers.
Rinse the lens under a faucet for several minutes to remove all of the etching material.
Dry the lens with a microfiber towel. Inspect the lens for signs of scratches of remaining coating. Repeat the process, if necessary.
Wear protective latex or rubber gloves when working with glass etching products
