Embodiment 1
[0028] The resin lens substrate 1 is selected as bisallyl diglycol carbonate (CR39). First, after ultrasonic cleaning, the hard coat layer 2 is coated by dip coating; then, under vacuum conditions, anti-reflection anti-reflection coating Film layer 3, select the order and thickness of raw materials according to the color required by the film layer; after ultrasonic cleaning again, select polycarbonate (PC) as the polymer hydrophilic film as the anti-fog film layer 5, with a thickness of 10 microns, using optical The transparent glue OCA glue is used as the connecting glue layer 4 to adhere the PC film to the anti-reflection and anti-reflection film layer 3 and cure at room temperature.
Embodiment 2
[0030] The resin lens substrate 1 is selected as unsaturated acrylic ester, first, after ultrasonic cleaning, the hard coat layer 2 is coated by dip coating; then, the anti-reflection and anti-reflection film layer 3 is plated under vacuum conditions, and according to the film layer Select the order and thickness of raw materials for the required color; after ultrasonic cleaning again, select polyethylene terephthalate (PET) as the polymer hydrophilic film as the anti-fog film layer 5, with a thickness of 50 microns, and use optically transparent glue The OCA glue is used as the connecting adhesive layer 4, and the PET film is adhered to the anti-reflection and anti-reflection film layer, and is cured at room temperature.
Embodiment 3
[0032] Select the resin lens base 1 as polyurethane, firstly, after ultrasonic cleaning, apply the hard coat layer 2 by dip coating; then, under vacuum conditions, coat the anti-reflection and anti-reflection film layer 3, according to the required color of the film layer Select the order and thickness of raw materials; after ultrasonic cleaning again, select cellulose acetate (CA) as the polymer hydrophilic film as the anti-fog film layer 5, the thickness is 30 microns, use optically transparent glue OCA glue as the connecting glue layer 4, put The CA thin film is adhered to the anti-reflection and anti-reflection coating layer and cured at room temperature.
