[0024] As shown in the figure, a resin lens for resisting strong stray light includes: a resin substrate 10, the front surface of the resin substrate 10 has a plurality of convex nano-microlight units, and the back surface has a plurality of concave nano-microlight units, the convex nano-microlight units increase the positive refractive power relative to the resin substrate 10, and the concave nano-microlight units increase the negative refractive power relative to the resin substrate 10; an organic silicon layer 20 dip-coated on the resin substrate 10; a low refractive index film layer 30 plated on the surface of the organic silicon layer 20; a polarizing layer 40 arranged on the surface of the low refractive index film layer 30; a high refractive index film layer 50 plated on the surface of the polarizing layer 40; a zirconium-titanium mixed layer 60 plated on the surface of the high refractive index film layer 50, and the zirconium-titanium mixed layer 60 includes a zirconium oxide layer and a titanium oxide layer.

[0025] In one embodiment of the utility model, a micro-light unit is formed on the surface of the resin substrate 10, which is convex on the front side to increase the positive refractive power and concave on the back side to increase the negative refractive power. The front and back sides cooperate to adjust the refractive power to change the defocus, improve eye fatigue, and also improve the refractive index and enhance optical transmittance.

[0026] The organic silicon layer 20 is formed into a dense hardened film layer by immersing the resin substrate 10 in a hardening liquid, thereby improving the surface hardness of the resin substrate 10. The low refractive index film layer 30 and the high refractive index film layer 50 cooperate with each other to sandwich the middle polarizing layer 40, which improves the refractive index, reduces the interference of strong stray light, enhances filtering, and also protects the middle polarizing layer 40, which is highly practical.

[0027] The zirconium-titanium mixed layer 60 is formed by combining a zirconium oxide layer and a titanium oxide layer, and can improve the anti-reflectivity of the lens.

[0028] Preferably, the outer side of the zirconium-titanium mixed layer 60 is further plated with an indium tin oxide layer 70 , and the indium tin oxide layer 70 has good optical transmittance enhancement.

[0029] The refractive index of the low refractive index film layer 30 of the utility model is 1.42-1.63, providing low refractive index variation. Further, the refractive index of the high refractive index film layer 50 is 2.03-2.21, providing high refractive index variation. The combination of the two can continuously reduce reflection and improve anti-reflection.

[0030] In addition, the zirconium-titanium mixed layer 60 is provided with 3 zirconium oxide layers and 3 titanium oxide layers, which are arranged in 6 layers, and the two are arranged alternately, that is, the first layer is a zirconium oxide layer, and the second layer is a titanium oxide layer, and then they are stacked, which greatly improves the optical transmittance.

[0031] In summary, the utility model improves the refractive power of the resin substrate and adjusts the refractive property through the nano-microlight unit. At the same time, the low refractive index film layer 30 and the high refractive index film layer 50 cooperate with the middle polarizing layer 40 to enhance the anti-reflection property of the lens, improve the stray light filtering and reflection, and the outer zirconium-titanium mixed layer 60 improves the transmittance.
