A chip in a sunglass lens might be a tiny imperfection, but it's still one that can bother you a great deal--particularly if you've spent a lot of money on a designer pair of shades. While you can fix a chip on the rim of a drinking glass by sanding it down aggressively, such a technique doesn't work on sunglass lenses. If you need to repair your sunglasses in a pinch, you can use a polymer scratch remover solution to your advantage.
Spray each lens with the resurfacing spray and rub in the spray with the cloth provided. Rinse each lens with cold tap water and pat dry again with the cloth.
Open the polymer scratch removal elixir and wipe down each lens with the provided wand. Create even, uniform strokes.
Examine each lens closely, pinpointing the chipped area in each one. Hold the sunglasses perfectly flat with the lenses facing up. Add an extra dot of polymer to each chip with the wand. Hold the sunglasses perfectly flat so that the polymer formula can sink into each chip and bond to the surface area, concealing and smoothing it.
