The lenses of Spotters Artic Sunnies are polarised and are made from Columbia Resin #39 or CR39. This is a plastic polymer used in the manufacturing of some of the world’s best optical lenses. It is lighter, sturdier, has a slightly lower refractive index and has a higher Abbe number in comparison to crown glass hence it results in lesser chromatic distortion.
CR39 material is transparent to visible light but it is opaque to ultraviolet light thus it blocks-off ultraviolet radiation while allowing natural visual light to pass through.
The lenses of the Spotters Artic Plus CR39 Sunglasses can withstand temperatures as high as 130 °C for as long as an hour and it can be used continuously at a 100 °C. Besides its resistance to high temperatures the material is also highly resistant to abrasion/scratches, in fact its resistance is the highest among all uncoated optical lenses.
