Plastic lens
A plastic lens is a transparent optical element made from optical-grade plastic materials. Its core function is the same as a glass lens — changing the light path through light refraction to achieve light convergence, divergence, or collimation — but due to material characteristics, it is more suitable for lightweight, low-cost, and impact-resistant scenarios. It shares the core logic of 'light refraction' with glass lenses: when light enters plastic from air, the change in propagation speed causes the light to bend; the convex/concave surface of the lens determines the light path direction — a convex surface converges light, and a concave surface diverges light. Plastic has a lower refractive index, so under the same optical effect a thicker curved surface must be designed; however, plastic density is only 1/2-2/3 that of glass, making it lighter and less prone to breakage. Plastic lenses have the following types: plastic convex lenses, plastic concave lenses, plastic combination lenses, etc.
