Polycarbonate Lenses Material (PC Lens) ( Helpful:6 ) Back »

*Refractive index (nd): 1.586
*Abbe value (Vd): 30
*Density: 1.2 g/cm3
*UV cutoff: 385 nm


While its optical characteristics are less than ideal, polycarbonate, the same material used for bullet-proof glass, is the most impact resistant of lens materials. Consequently, polycarbonate is the material of choice for safety and children’s eyewear. With an index of 1.59, polycarbonate also produces thinner, lighter lenses than glass or plastic. These factors along with polycarbonate’s inherent UV protection and pricing make it a popular material.



Thinner and lighter than glass and plastic
Highly impact resistant (used for safety glasses)
Inherent UV protection



Poor optical quality
Susceptible to scratching (correctable by coating)
Susceptible to stress fractures in drill mounts
Does not readily accept tint
