step one: weighing epoxy acrylic resin, cyclosulfamate, isocyanate, a polythiol compound, dibenzyl maleate, divinylbenzene and a blue light absorbent according to the weight parts of the raw materials, and adding the raw materials into a stirrer for uniform stirring;
step two: then adding 1-3 parts of initiator into the stirrer, degassing, injection molding and then putting into an oven;
step three: heating the oven, heating to 140-155 ℃ within 6-10h, and then preserving heat for 2-3h;
step four: and after the heat preservation is finished, cooling the temperature to room temperature from 140-155 ℃ within 1-3h to obtain the high refractive index optical resin.
8. The improved high refractive index resin monomer as claimed in claim 7, wherein in said step one, the stirrer is stirred for 35 to 50min at a stirring speed of 400 to 600r/min.
9. The improved high refractive index resin monomer as described in claim 7, wherein said initiator in said step two is one of azobisisobutyronitrile and benzoyl peroxide.
