Headlight restoration or plastic headlight restoration is the act of restoring aged headlight lenses that have become discolored or dull due the original factory UV protective coating degrading primarily due to UV light and other environmental factors such as road debris impact (stones, sand, etc.) rain, and exposure to caustic chemicals.
Plastic coating is a term that is commonly used in technology but is nevertheless ambiguous. It can be understood to mean the coating of plastic (e.g., metallization of plastics [ 1 ] ) or the coating of other materials (e.g., electrical cable ) with plastics.
Plastic lenses are lighter and shatter-resistant, but are more prone to scratching. Polycarbonate plastic lenses are the lightest, and are also almost shatterproof, making them good for impact protection. CR-39 is the most common plastic lens, due to low weight, high scratch resistance, and low transparency for ultraviolet and infrared radiation.
Anti-scratch coatings are often used on plastic products wherever optical clarity, weathering, and chemical resistance are required. Examples include optical discs , displays, injection-molded parts, gauges and other instruments, mirrors, signs, eye safety/protective goggles, and cosmetic packaging.

The lens fungus [2] does not feed on the glass itself, but on materials that were used in the manufacture [3] of the optics and/or that adhere to it (leather, paint, wood, putty, adhesives, fibers). Lens surfaces can be attacked if organic material has deposited on them, [4] such as fingerprints or vapors from plastics or grease. The fungus can ...
Plastic lenses are currently the most commonly prescribed lens, owing to their relative safety, low cost, ease of production, and high optical quality. The main drawbacks of many types of plastic lenses are the ease by which a lens can be scratched, and the limitations and costs of producing higher-index lenses.
Plastic rings will (hopefully) soon be eliminated. This hack might soon be an unnecessary relic of the past. Fortunately, many brands are making efforts to reduce or eliminate single-use items ...
