What Does a Lens Look Like?

It is a circular glass cover, resembling a convex lens like a magnifying glass. The function of a car light lens: The car light lens can reflect the scattered light of the bulb into parallel beams, significantly enhancing the brightness and ensuring sufficient illumination within a range of 150-400M in front of the car. At the same time, in the low beam state, the light does not diverge, but provides good ground illumination without causing glare or affecting the normal driving of oncoming vehicles. Types of car light lenses: Lenses are divided into two types: single-beam lenses and dual-beam lenses. A single-beam lens controls one bulb and is a dedicated product, with separate high and low beams. A dual-beam lens can switch between high and low beams through an internal shutter.
The lens is the transparent cover on the front of a car's headlight, resembling a semi-circular plastic shield that covers the bulb. It feels smooth to the touch and is often made of polycarbonate, which is impact-resistant and refracts light. After years of driving, I've noticed it usually has small ripples or grid patterns on the surface to control light direction and avoid blinding oncoming drivers. Located on both sides of the front bumper, it easily collects dirt or turns yellow over time. Severe oxidation can make it hazy and reduce visibility at night. I always use a soft cloth and water wax for cleaning to maintain brightness and safety. Avoid using hard brushes to prevent scratches. When upgrading to a new lens, choose one with high transparency for a cooler look and better durability.
