Can I Use a Headlight Restoration Kit to Remove Scratches from Sunglasses?

Using a headlight restoration kit to remove scratches from sunglasses is not recommended. Headlight restoration kits are formulated for automotive plastics, making them unsuitable for the lens materials used in sunglasses, which can include CR-39 standard plastic or polycarbonate. These lenses are more delicate and susceptible to damage from the harsh chemicals and abrasives contained in these kits. Instead, several alternative methods are available for dealing with scratches on sunglasses. This article will guide you through the best approaches and potential risks to consider.

Alternative Methods to Remove Scratches from Sunglasses

Toothpaste: Opt for a non-gel, non-whitening toothpaste. Apply a small amount to a soft cloth, then gently rub the scratched area in a circular motion. Rinse with water and dry with a clean cloth. Baking Soda Paste: Mix baking soda with water to form a paste. Apply it to the scratches and gently rub with a soft cloth. Rinse and dry to reveal a smoother surface. Commercial Scratch Remover: Choose products designed specifically for plastic lenses, which can help reduce the appearance of scratches. Replacement: For deep or extensive scratches, replacing the lenses or the sunglasses altogether might be the most effective solution.

Testing Any Method on a Small Area

Before applying any method to your sunglasses, perform a test on a small, inconspicuous area to ensure it won't cause additional damage. This precautionary step can save you from unnecessary repairs or further harm to your lenses.

Understanding Your Sunglasses Lenses

Your lenses may be made of 'DriveWear' – polarized photochromic plastic with a scratch-resistant coating. This coating can be compromised by the abrasive chemicals in headlight restoration kits. If your glasses are either CR-39 standard plastic or polycarbonate, similar to Lexan, a headlight restorer would not be an appropriate choice.

Manufacturers’ Warranties and Professional Help

Consider that if your lenses are prescription, they often come with a limited scratch warranty. However, non-prescription or other types of polarized photochromic lenses may not be covered. Scratches that are initially minor can escalate into larger, hazy patches that make the glasses unusable. Over the years, I have personally experienced clients who tried to fix scratches using buffing wheels, acetone, fine sandpaper, or other chemical products, only to find that they compromised the lenses further and voided warranties in the process.

For the best results, it is advisable to consult a professional optician or eyewear repair specialist who can provide safe and effective solutions for your sunglasses. Proper maintenance and regular cleaning will also help prolong the life and appearance of your sunglasses.
