Description

technical field

The utility model relates to a structure of an optical object, in particular to a structure of an optical object with rapid discoloration and fading, high wear resistance, high manufacturing yield and long service life. the

Background technique

At present, many optical objects used to protect the eyes from direct light, such as: building curtain lenses, car windshield lenses, helmet goggle lenses, glasses lenses, computer screen lenses, etc., are all equipped with anti-polarization The dye makes this optical object have a darker color, so as to resist the ultraviolet rays of sunlight and light scattering to produce strong reflected light (commonly known as glare). The effect dye also has the function of preventing ultraviolet rays and glare. However, the environments and occasions based on use are not always the same. Therefore, the above-mentioned functions of this optical object are still not enough to cope with changing environments and occasions. The intensity is different, if you maintain a consistent dull color indoors, it will be inconvenient to use. the

In view of this, another optical object with color-changing function has been developed, which is to impregnate the optical object with polarizing function with color-changing dyes, so that the surface of this optical object has more color-changing properties with the use of different environments. Color changing function. In other words, when this type of optical object is irradiated by sunlight through the color-changing dye, the optical object will undergo chemical changes and change color due to energy excitation, and will return to its original color when it is away from sunlight. There is following defect in existing this optical object and needs to be improved, namely:

The speed of color change is inconsistent. Since the color-changing dye is attached to the optical object by means of exhaust dyeing, the ratio of the color-changing dye attached to the optical object at the initial and final stages of immersion in the dye tank is different, resulting in different strengths for absorbing sunlight, which directly affects The inconsistency of the color changing function makes it difficult to control the uniformity of manufacturing quality. the

Poor abrasion resistance. Due to the dip dyeing method, the two surfaces of the optical object are attached with color-changing dyes. Therefore, once wiped, the color-changing dye layers on both surfaces of the optical object will be rubbed and damaged, resulting in scratches. Due to the uneven force, the degree of damage to the color-changing dye layer on the two surfaces of the optical object is different, so that the color-changing functions of the two surfaces of the optical object are inconsistent. the

Manufacturing defective rate is high and life is short. To achieve a certain degree of color-changing effect, the attached color-changing dye layer is regulated to a certain thickness, and as mentioned in the previous paragraph, because it is carried out in a dip-dyeing manner, the uniformity of the thickness is quite difficult to control, so the defect rate is very high. In addition, the poor abrasion resistance mentioned in the previous paragraph greatly shortens the service life. the
