Comparing Polycarbonate Lenses With Standard CR39 Lenses


CR-39 alludes to the material that is utilized to make the greater part remedy focal points. It is an optical grade plastic polymer perceived for its light weight, compound obstruction properties and ‘color capacity’. In similar solutions it is roughly a portion of the heaviness of glass focal points, while being somewhat thicker. Its effect obstruction is more prominent than glass however doesn’t ascend to the degree of polycarbonate and it ought not be considered for applications where effects are pervasive. On this premise, it isn’t suggested for dynamic games and motorcycling. It is more scratch safe than polycarbonate, however will scratch while possibly not appropriately dealt with.


Polycarbonate is an effect safe material. It is becoming utilized all the more broadly as of late – particularly for motorcycling and activity sports. It is likewise utilized habitually for the coating of rimless edges in light of these properties. In spite of the fact that hard coated polycarbonate  is influence safe, it ought not be thought of as indestructible. Polycarbonate is the most grounded material accessible and will tend to break into bigger parts, rather than the CR39’s more modest pieces, and is, thus, less unsafe. Polycarbonate is more slender than standard CR39.


Polycarbonate focal points are multiple times more effect safe than different plastics making them profoundly reasonable for activity sports or society that are a bit (will we say) cumbersome! They offer UV security and prevent 99.9% of beams from the sun, glaring lights and PC screens. Our polycarbonate focal points are provided with a scratch safe covering and are more slender than standard focal point and consequently more agreeable to wear.


Correlation of Focal point Materials and Material Qualities




– Most grounded material for influence obstruction

– Lightweight

– Can be covered for scratch opposition

– Most have implicit UV radiation insurance


Plastic (CR39)


– Around one-a portion of the heaviness of glass

– Impervious to solvents and pitting

– More decisions for coatings and coloring
