Abstract

A hidden sunglass is formed by curvature glasses, wherein, the curvature glass is formed by a soft ultraviolet corneal contact glass and a colorful print layer combined at the outer side of soft ultraviolet corneal contact glass, the soft ultraviolet corneal contact glass is made from the hydroxyethyl methacrylate containing anti-ultraviolet absorber, the colorful print layer is made from the nanometer harmless inactive paint and macromolecule organic material. The utility model has the advantages that it uses some anti-ultraviolet absorber and the deep-color colorful print layer to baffle and filter the ultraviolet, to improve the function of hidden sunglass. Compared with traditional sunglass, the invention has stronger functions.

Description

Stealthy sunglasses

Technical field

The utility model relates to a kind of stealthy sunglasses, be a kind of have correcting spectacle lens ametropia, prevent the ultraviolet ray to the injury of eyes and the multi-functional contact lenses of beautification function.

Background technology

The function of existing soft corneal contact lens (abbreviation contact lenses) mainly is the beautification function that the ametropia of correcting spectacle lens and part eyeglass have, and does not have ultraviolet interception.For the outdoor activities person under the high light, need a kind of than common sunglasses more easily, can prevent the contact lenses of ultraviolet ray to eye injury.

Summary of the invention

The purpose of this utility model just provides a kind of stealthy sunglasses, to satisfy people to preventing the demand of ultraviolet contact lenses.

The technical solution of the utility model is: the curve lens of this stealth sunglasses is made of with the colour printing and dyeing layer that is compounded in its outside is compound the soft ultraviolet contact lens of antiultraviolet.

Described soft ultraviolet contact lens is that initial point, diameter are 13.8～14.2mm with its center; The central diameter of described soft ultraviolet contact lens is that the zone of 6～8mm is a central optical zone 11, is pupil position, and the transmittance of this central optical zone is the cornea zone outside central optical zone greater than 80%; The central area that it is 10mm～12mm that described colour printing and dyeing layer covers soft ultraviolet contact lens outside diameter.

Described soft ultraviolet contact lens is made by the poly hydroxy ethyl acrylate material that contains the antiultraviolet absorbing agent; The colour printing and dyeing layer is made up of nano level nontoxic non-stimulated dyestuff and macromolecule organic material.

Advantage of the present utility model is to have improved the use effect of contact lenses under high light greatly owing to adopting an amount of antiultraviolet reagent and effectively keeping out and ultraviolet ray filtering by the colour printing and dyeing layer of dark color.This stealthy sunglasses is compared with traditional sunglasses, and great lifting is all being arranged aspect convenience and the comfortableness, has good market outlook for the crowd of outdoor activities under the high light.

Embodiment

Referring to Fig. 1 and Fig. 2, the utility model adopts soft ultraviolet contact lens 1 of antiultraviolet and colour printing and dyeing layer 2 two-layer composite, and 2 printing and dyeing of colour printing and dyeing layer are integrated with it in soft corneal contact lens 1 outside.Described soft ultraviolet contact lens 1 is that initial point, diameter are 13.8～14.2mm with its center, and its central diameter is that the zone of 6～8mm is an optical zone 11, is pupil position; The transmittance of this central optical zone is greater than 80%; It outside central optical zone 11 cornea zone 12.It is the central area of 10mm～12mm that described colour printing and dyeing layer 2 covers soft ultraviolet contact lens 1 outside diameter.Colors such as 2 employing of colour printing and dyeing layer are grey, black, green, purple stimulate to guarantee effectively to keep out high light.Contain sufficient ultraviolet light absorber in soft ultraviolet contact lens 1 and the colour printing and dyeing layer 2, guarantee powerful anti-ultraviolet function.

Described soft ultraviolet contact lens 1 is made by the poly hydroxy ethyl acrylate material that contains the antiultraviolet absorbing agent; Colour printing and dyeing layer 2 is made up of nano level nontoxic non-stimulated dyestuff and macromolecule organic material.

The manufacturing of stealthy sunglasses of the present utility model is except that increasing the color dyeing process, and other and common contact lenses are made identical.Nontoxic, non-stimulated dyestuff is selected in the color printing and dyeing for use, meets U.S. FSDA standard.Characteristics of the present utility model are can keep out high light to stimulate; Can effectively absorb ultraviolet light, prevent the injury of ultraviolet ray eyes; Make the more shiny black god of having of glasses after wearing, elegant in appearance.
