[0022] Example 1
[0023] A preparation method of a heat-aging resin lens, comprising the following steps: Step 1: Dissolving an antioxidant and a light stabilizer in a solvent, and after forming a transparent homogeneous solution, then adding it to a monomer, and at a temperature of 40° C. Dissolve the UV agent, then cool down to room temperature, add the initiator;
[0024] Step 2: Stir the raw materials for 2 hours at room temperature and the vacuum degree is -0.1MPa, filter through a 0.1μm filter element, add pigment blue and pigment red, continue stirring for 0.5 hours, and vacuumize 1 under the condition of vacuum degree -0.1MPa Hour;
[0025] Step 3: The static raw material is filtered again through 7μm filter paper, poured into the mold, and sealed in the mold with adhesive tape;
[0026] Step 4: Put the mold into the curing oven to heat up and cure once according to the corresponding curing curve;
[0027] Step 5: After the first curing, open the mold, take out the...

[0058] Example 3
[0059] A method for preparing an anti-heat-aging resin lens, comprising the following steps: Step 1: Dissolving an antioxidant and a light stabilizer in a solvent, and after forming a transparent homogeneous solution, then adding it to a monomer, and cooling at 40-60° C. The UV agent is dissolved at the temperature, and then the initiator is added after cooling to room temperature;
[0060] Step 2: Stir the raw materials for 3 hours at room temperature and a vacuum degree of -0.07MPa, filter with a 0.1 μm filter element, add pigment blue and pigment red, continue stirring for 1.25 hours, and vacuumize for 2 hours at a vacuum degree of -0.107MPa Hour;
[0061] Step 3: The static raw material is filtered again through 7μm filter paper, poured into the mold, and sealed in the mold with adhesive tape;
[0062] Step 4: Put the mold into the curing oven to heat up and cure once according to the corresponding curing curve;
[0063] Step 5: After the first curing...
