Description

Substrate color-changing lens

Technical Field

The utility model relates to a lens production field, in particular to substrate lens that discolours.

Background

Color changing lenses, also known as "photosensitive lenses". Silver halide is added into the glass lens, but at present, resin color-changing lenses are mainly used, chemical substances such as a pyriproxyfen and the like are added into the acrylic resin lenses, and the originally transparent and colorless lenses can be changed into colored lenses for protection when being irradiated by strong light, so that the glass lenses are suitable for being used indoors and outdoors. The color-changing lens is made of optical glass containing silver halide microcrystals, and can quickly darken under the irradiation of sunlight and ultraviolet rays according to the principle of light color interconversion reversible reaction, completely absorb the ultraviolet rays and realize neutral absorption of visible light; and the color and the transparency can be quickly recovered when the lamp returns to the dark. The color-changing lens is mainly used in outdoor, snowfield and indoor work places with strong light sources to prevent sunlight, ultraviolet light and glare from damaging eyes.

The existing color-changing lens needs about 20 seconds for changing from light color to dark color and about 50 seconds for changing from dark color to light color, the using effect is not ideal, and the lens is of an arc-shaped structure, and the color change is uneven along with the change of light, so that the improvement is needed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides a substrate lens that discolours, through fall into three region with the lens, adopts the different mode of discolouing, makes to discolour more evenly, and the stable performance reduces the amazing and the eyestrain of alleviating of eyes, protects eyes. The utility model discloses a substrate color-changing lens, which comprises a first optical part positioned in the center, wherein the first optical part is provided with color-changing particles which are uniformly dispersed, and the outer side of the first optical part is provided with a TAC film layer; the second optical part is positioned at the outer ring of the first optical part; a color changing film layer is arranged on the outer side of the second optical part, and a TAC film layer is arranged on the outer side of the color changing film layer; and a third optical part positioned on the outer ring of the second optical part, wherein a photochromic layer is arranged outside the third optical part, and a TAC film layer is arranged outside the photochromic layer.

According to an embodiment of the present invention, the color-changing film layer is formed by spin-coating the color-changing liquid on the second optical portion, curing by infrared heating, and cooling.

According to an embodiment of the present invention, the photochromic layer is formed by alternating 4 layers of silver bromide and copper oxide.

Compared with the prior art, the application can obtain the following technical effects:

1) by dividing the lens into three areas and adopting different color changing modes, the color changing is more uniform, the performance is stable, the stimulation to eyes is reduced, the eye fatigue is relieved, and the eyes are protected.
