Material is added in injection machine, is obtained by mould molding, blank eyeglass；D, anti-blue light coating raw material is added to into reactor
It is interior, and anti-blue light coating material is obtained under nitrogen atmosphere；E, the blank eyeglass that step C is obtained is cleaned up, anti-blue light is plated
Layer material is added in vacuum coating equipment, and the blank eyeglass that finishes of cleaning is put in vacuum coating equipment carries out anti-blue light coating
Coating problems, the then prebake 15min at a temperature of 51-55 DEG C, then after 8-9h being toasted at a temperature of 88-92 DEG C obtaining mirror
Piece finished product.
