Description
Technical Field
The utility model relates to the technical field of optical devices, in particular to a multifunctional optical coating goggles lens.
Background
Human beings are in various illumination environments, whether natural light or artificial light sources, on one hand, the light sources bring illumination to people, help people form vision, and observe and learn the world; on the other hand, ultraviolet light, visible light and infrared light generated by the composite material are harmful to human eyes to different degrees. In recent years, with the development of science and technology and multimedia platforms, electronic screens such as televisions, computers, mobile phones and the like are continuously full of people's lives, the development of network technology and the requirements of modern families and offices promote more young people to become computer families and mobile phones, and the eye health problem is becoming serious. The screens contain blue light which is harmful to human eyes, so that the amount of toxins in a macular region in the eyes is increased due to the blue light, eyeballs are damaged, the eyesight is affected, and the eye health of people is seriously threatened. While many near-infrared optical devices for medical use inevitably reflect through various ways even directly penetrate into human eyes due to misoperation in the process of being used by operators, and the high-risk people with eye injury are very necessary to wear protective lenses to effectively prevent the eyes from being injured by light of various wave bands.
The main damage parts of the human eyes by ultraviolet rays are cornea and crystalline lens, and retina, vitreous body macula part and the like can be damaged. Repeated uv irradiation can cause chronic blepharitis and acute keratoconjunctivitis.
The blue light is the light closest to the ultraviolet light wave and with the highest energy, and the wavelength is between 400 and 500 nm. The retina can be damaged by long-term exposure to blue light, the vision of serious people can be damaged, maculopathy is caused, and symptoms such as red eye, dry eye, eye puckery, blurred vision, asthenopia, pain in head, shoulders and cervical vertebra can appear. Research shows that blue light exists not only in sunlight, but also in computer monitors, fluorescent lamps, mobile phones, digital products, projectors and the like in large quantities. The short-wave blue light has extremely high energy, can penetrate through crystalline lens to directly reach retina, causes optical damage to the retina, directly or indirectly causes damage to cells in a macular region, and increases the toxin amount in the macular region in eyes by the blue light, thus seriously threatening the eye ground health of people.
The damage of infrared rays (mainly near infrared wavelength of 780-1400 nm) to eyes is mainly caused by corneal stroma protein damage and corneal opacity caused by high temperature, and cataract is caused by partial opacity of crystalline lens. It can also cause chronic blepharitis and conjunctivitis. Workers working for a long time under infrared rays can also have dry eye symptoms caused by the continuous evaporation of the tear film and the unsmooth secretion of accessory lacrimal glands, and some workers can also have the early-aged phenomenon of the decline of eye regulation.
Studies have shown that when light is shone on the eye, about 4% of the light is reflected off the cornea and the majority will be absorbed through the cornea, aqueous humor, lens and vitreous individually and eventually to the retina. The light emitted by the high-power artificial light source is mostly in a non-panchromatic spectrum, the spectral components comprise infrared light and ultraviolet light, and the absorption capacity of crystals and corneas to the ultraviolet light is the largest. Therefore, long-term irradiation with a lamp rich in ultraviolet rays induces electric ophthalmia, which causes clouding of the lens, and cataract and inflammation of the cornea and conjunctiva. The light reflection coefficient of smooth and white paper is as high as 90%, which is about 10 times higher than that of lawn, forest or wool surface ornaments. The paper used in many publications today is very bright and smooth, has a high reflectance and feels tired in a short time. It has been found that long-term reading of a book of particularly smooth paper can cause damage to the cornea and iris of the human eye, inhibit the function of the retinal photoreceptor cells, and cause asthenopia and impaired vision. The myopia rate of high school students in China is as high as 60%, and related experts consider that the visual environment is the main reason for forming myopia rather than the habit of using eyes.
