Antifogging lens

Technical Field

The application belongs to the technical field of lenses, and particularly relates to an antifogging lens.

Background

Original resin lens produces the fogging very easily in the environment that has the difference in temperature, the lens piece fogging means that the steam in the environment air of difference in temperature greatly reaches the saturated condition, condense at the lens surface and form tiny liquid drop formation fog, these liquid drops refract and scatter light on the one hand, the optical property on lens surface has been changed, the light transmissivity has been influenced, cause the nontransparent phenomenon of lens, on the other hand, also can make the wetting of lens surface different degree, thereby cause the surface corrosion problem because the humidity brings, bring a great deal of inconvenience for the life from this.

SUMMERY OF THE UTILITY MODEL

In view of this, the technical problem to be solved by the present application is to provide an anti-fog lens, in which a hydrophobic film layer and a hydrophilic film layer are respectively disposed on optical convex surfaces with different curvatures, so as to avoid the trouble of poor anti-fog effect in the past.

In order to solve the technical problem, the utility model discloses an antifogging lens, which comprises a lens base body, wherein the lens base body is provided with an optical concave surface and an optical convex surface, the optical convex surface comprises a first optical surface positioned in the center and a second optical surface annularly arranged on the edge of the first optical surface, and the curvature of the first optical surface is larger than that of the second optical surface; sputtering the hydrophobic film layer on the second optical surface in vacuum; the hydrophilic film layer is coated on the first optical surface and provided with a nano-scale hydrophilic hole; and an anti-UV layer plated on the optical concave surface.

According to an embodiment of the present invention, the nano-scale hydrophilic pores have a gap of 10nm to 1000 nm.
