Refinishing aged headlight lenses that have become discolored or dull due to oxidation primarily due to UV light and other environmental factors such as; road debris impact (stones, sand, etc...) rain, and exposure to caustic chemicals. Over time the protective hardcoat breaks down with UV degradation and wear from abrasion. If left untreated the headlights will eventually develop small surface cracks, a condition referred to as crazing. The effectiveness of the headlight in terms of light output measured by LUX can be significantly reduced. This condition which results in hazy and discoloured lenses, known for causing reduced night time visibility for travelers as the condition worsens. It is possible for cloudy and hazy headlights to be restored to a like-new condition and represents typically a far more economical alternative than replacing the lens.
