OCCO Nano sunglass lens,high definition
Material:imported cr-39(America PPG) with nano metal oxide
Dia:75mm
Ct:2mm
Abbe:58
Index:1.499
Color:brown,gray,green,blue
High definition:
1.The size of nano metal oxide particle is 20—40nm;however, the visiable light range can be 380—760nm,less than the range , can totally go through the lens linearly. It also has better permeability than the traditional lens.
2.The material of non-coated lens is CR-39, refractive index is 1.499 , abbe value is 58. It is blended with nano particles and has super high image quality.
