Description
Technical Field
The utility model relates to a technical field of lens, in particular to lens with prevent blue light function.
Background
As is well known, with the development of intelligent technology, more and more electronic products are emerging, and the main light source of the electronic products is blue light. The wavelength of the blue light is between 380nm and 500nm, and the blue light has relatively high energy. Scientific research shows that blue light is harmful to human bodies, particularly has the largest harmful effect on eyes, and the damage of the blue light to the eyes mainly comprises the following aspects:
(1) The blue light directly irradiates the transparent crystal, and the transparent crystal can cause cataract after absorbing the blue light;
(2) Part of the blue light can reach the fundus through the transparent crystal, contact the retina of the fundus, affect retinal pigment epithelial cells and retinal tissues, so that the retinal tissues are changed, atrophy and degeneration are caused, and eye diseases including macular degeneration and the like are caused;
(3) Blue light can also cause myopia; the blue light has shorter wavelength, is mainly focused in front of retina, and causes myopia after long time; at present, the public has more and more great demand on electronic products, and when the electronic products such as mobile phones, computers, LED lamps and the like are used for a long time, the damage to eyes is great, and the myopia rate is continuously increased;
(4) Blue light can also affect sleep; the melatonin fading is beneficial to sleep, the problem of time difference is solved, and if the melatonin is reduced by blue light irradiation, the sleep quality is influenced.
The traditional effective solution for preventing blue light is to carry out film pasting treatment on an electronic product or wear eye protection glasses for preventing blue light, the film pasting technology can only prevent the blue light of the electronic product from penetrating and emitting, but cannot prevent the blue light generated by the sun and an illumination lamp, and the blue light preventing lens makes up the defects of the film pasting technology. Therefore, lens manufacturers invest manpower and financial resources, research and develop blue-light-proof lens technologies, various blue-light-proof lens products are produced at the same time, and related patent technologies also appear.
Most of the existing blue-light-proof lenses are manufactured by adding blue-light-proof toner into a lens base material, mixing and stirring the mixture and performing injection molding, or are manufactured by a reflection-type multilayer coating technology. However, the blue-light-proof lens made by adding toner has yellow color, so that the customer acceptance is not high; the blue light prevention lens made by coating reflection has higher cost. Moreover, most of the blue-light-proof lenses on the market obstruct short-wave blue light within the range of 380nm-440nm, while the blue-light wave bands emitted by various electronic products which are currently prevalent are mainly concentrated within the range of 440nm-460nm, and the existing blue-light-proof lenses have poor effect or even no effect on obstructing the blue light of the electronic products.
In view of the above, the present inventors developed a blue light prevention lens through repeated design, test, modification and test by means of the professional skill level and accumulated experience of long-term research, design and manufacture and familiarity with the structural performance of the product, and the present application resulted therefrom.
