Description

Blue light testing arrangement is prevented to lens

Technical Field

The utility model relates to a blue light testing arrangement is prevented to lens.

Background

Blue light is an important component of visible light, natural world does not have independent white light, and the blue light, green light and red light are mixed to form white light. The green light and the red light have small energy, small stimulation to eyes, short blue light wave and high energy, and can directly penetrate through crystalline lens to directly reach the macular area of the eyes, thereby causing macular degeneration. A large amount of blue light is reserved in artificial light sources such as LEDs and computer background light, so that the light sources are whiter and brighter, and some light sources, particularly white and bright light, give people a bluish feeling, which is caused by an excessively high proportion of blue light. Visible light emitted by various novel artificial light sources such as various computers, television screens, energy-saving lamps and the like contains a large amount of short-wave blue light with irregular frequency. The long-term blue light irradiation on the retina can generate free radicals, and the free radicals can cause the retinal pigment epithelial cell to die, thereby causing various ophthalmic diseases such as retinopathy and the like. People who use mobile phones and work with computers for a long time have higher and higher eye diseases, so the blue-light-proof glasses also become hot-market products.

The existing testing device for the blue-light-proof glasses is high in cost, complex in structure and fixed in position, a light source emitted by blue light is aligned to the centers of the lenses and the testing area, and the blue-light-proof effect is judged through a central point. However, different eyeball focal lengths are different, and the thicknesses of the lenses are different, so that if the blue light prevention effect of the glasses is measured only, the blue light prevention effect of the glasses cannot be accurately judged, and the obtained effect is more one-sided.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the application provides a blue light testing arrangement is prevented to lens that easy operation, low price, flexibility ratio are high, and concrete implementation is as follows:

a lens anti-blue light testing device comprising: blue light generator, light source remove frame, glasses mirror support, blue light test card, the light source removes the frame and includes support frame and adjustable shelf, be equipped with the confession on the body of adjustable shelf the fixed mounting hole of blue light generator, the body bottom of adjustable shelf is equipped with grafting portion, grafting portion is equipped with the first groove of sliding of vertical direction, be equipped with the confession on the body of support frame the fixed slot of activity about the grafting portion be equipped with the second sliding groove that matches with the first sliding groove in the vertical direction of fixed slot, the fastener passes through first sliding groove and second sliding groove will blue light generator fixes on appointed height.

In one or more embodiments of the present invention, the blue light generator employs a light source with a wavelength band of 395-405 nm.

In one or more embodiments of the present invention, the support frame is L-shaped.

The utility model discloses the beneficial implementation effect who brings is: the blue light generator is detachable, and when the lens is required to test the resistance effect of different light sources (such as blue light, ultraviolet light and the like with different wave bands), only the corresponding light source generator is required to be installed in the installation hole of the movable frame; when the different positions of the lens are required to be tested for resisting the blue light, the horizontal height and the vertical height of the blue light generator are only required to be adjusted. The device simple structure, low cost and ability reply different light source test demands can also carry out the integrated test to different positions of lens, and application scope is wide, excellent in use effect.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings 1-2 and the embodiments:

a lens anti-blue light testing device comprising: the eyeball simulator comprises a blue light generator 1, a light source moving frame 2, a spectacle holder 3, an eyeball simulator 4 and a blue light test card 5, wherein the eyeball simulator 4 is of a round hollow structure as a whole, a high-transmittance resin material is arranged in the middle of the front end of the eyeball simulator 4, the blue light test card 5 is attached to the inner part of the rear end of the eyeball simulator 4, and the center of the blue light test card is flush with the center of the eyeball simulator 4; the light source moving frame 2 comprises a support frame 21 and a moving frame 22, a mounting hole for fixing the blue light generator 1 is formed in a body 221 of the moving frame 22, an insertion part 222 is arranged at the bottom of the body 221 of the moving frame 22, the insertion part 222 is provided with a first sliding groove 2221 in the vertical direction, a fixing groove 211 for enabling the insertion part 222 to move up and down is formed in the body of the support frame 21, a second sliding groove 2111 matched with the first sliding groove 2221 is formed in the vertical direction of the fixing groove 211, and a fastener (not shown) fixes the blue light generator 1 at a designated height through the first sliding groove 2221 and the second sliding groove 2111. For material saving, can set up support frame 21 wholly to be the L type, when the length of light source is longer, its focus leans on the back, support frame 21 sets up to design the L type, can provide more stable support.

During the test, place glasses 6 that await measuring on glasses mirror support 3, adjust blue light generator 1 height through movable support 22, adjust blue light generator 1 horizontal position through removing support frame 21, can be with blue light generator 1's luminous center and the center of glasses 4 that await measuring during the test initial value, eyeball simulator 4 center parallel and level, open blue light generator 1 switch and take place the light source, the 5 facula circumstances of record blue light test card, close behind blue light generator 1 switch, readjust blue light generator 1 height again, horizontal position, the blue light effect is compared in preventing of the different positions of glasses 6 that await measuring of test respectively and the record, the whole blue light effect of preventing of this glasses 6 that await measuring of comprehensive judgement. The equipment has the advantages of simple structure, convenient operation and good application value.

In addition, this application owing to adopted separately to install blue light generator 1 in the mode that the light source removed frame 2 alone, when needs carry out multiband blue light test, prevent ultraviolet ray test to glasses 6 that await measuring, only need change blue light generator 1, with other wave band blue light generators or ultraviolet light generator etc. install the mounting hole at adjustable shelf 22 can, consequently can deal with multiple test demand, application scope is wide.

Through the comparison of a plurality of groups of tests, the blue light generator 1 can more quickly and accurately reflect the blue light prevention effect of the glasses 6 to be tested by adopting the light source with the wave band of 395-405nm, so that the application preferentially adopts the light source with the wave band of 395-405nm to test.

The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
