There are more and more varieties of glasses, and the classification is getting more and more detailed. In addition to myopia glasses, reading glasses, sunglasses, it also includes driver protective glasses, computer protective glasses, leisure goggles and sports goggles, which are suitable for special industries, special work and leisure and entertainment. Moreover, the progress of the times promotes the maturity of people’s consumption hearts. Consumers pay more attention to the diversification and individualization of products. As a professional manufacturer of glasses, we have been committed to the research, development and sales of new varieties and new styles of glasses, and can customize any glasses according to customer requirements.
Myopia glasses mainly include frame glasses and contact lenses. With the increasing demand for glasses by people who love beauty, myopia has begun to combine the beautiful nature of sunglasses, and many new products have come out. The addition of contact lenses can be regarded as a supplement in terms of myopia. The popularity of contact lenses has a sufficient reason: it eliminates the trouble of frame glasses, does not affect the appearance, and the feeling of seeing objects is more three-dimensional.
“Contact lenses” are small and thin artificial plastic lenses placed on the cornea. Its main purpose is: correction of refractive errors, treatment of corneal diseases, beauty, and work or professional convenience (such as athletes, microscope or camera users).
Color contact lenses have also begun to approach the general population. They not only improve vision, but also enable wearers to change the color of their eyes according to their own preferences, which greatly meets the needs of beauty lovers. Not only that, contact lenses with UV protection are also very popular. Since contact lenses cannot reflect, absorb and scatter UV rays like frame glasses, they can accurately focus external light in the eyes, which may cause UV rays to attack the eyes. At present, UV-resistant contact lenses on the market can block 95% of UV rays, which can greatly prevent UV rays from damaging the eyes.
2. Reading glasses
At present, there are two prescriptions for reading glasses: one is to adjust the power of glasses with clear objects at close range, plus 1/3 of the power for adjustment; the other is to use low power that can see close objects clearly . The practice of many elderly people has proved that the latter two methods are better.
Sunglasses have a visible light transmittance of about 20%, and absorb ultraviolet and infrared rays well. It also has a variety of colors such as light green, light gray, light tea, etc., which are used to make sun-shading and protective glasses for snow work. Among them, light gray lenses have little effect on color recognition; light tea glasses make the blue sky look darker and reduce the transmission of green light; light green lenses reduce the transmission of red light.
Sunglasses not only have a wide range of varieties, but with the improvement of decoration and health care effects, their scope of use has become more extensive, and the time to update sunglasses can be described as rapid. Fashionable men and women have multiple sunglasses to match clothes to satisfy themselves in pursuit of fashion. In the heart.
4. Computer Protective Glasses
With the popularity of televisions and computers, electromagnetic radiation has become the number one killer of vision. The invention of radiation-proof glasses is even more popular, and its market is widely optimistic.
The lens design of the computer protective goggles has no side effects on vision. Refined by high-tech vacuum ion coating, it can block electromagnetic waves 100%. The lens contains anti-radiation substances, has the function of absorbing positive charges, can absorb low-frequency radiation microwaves, and avoids potential eye fever, headache, fatigue, and dryness caused by electromagnetic wave radiation. And other adverse symptoms. The penetration and absorption function of different light can resist radiation and glare, and the user will obviously feel clear and natural vision after wearing it. Now there are mainly anti-blue lenses and anti-fatigue lenses, which can effectively prevent blue light radiation and relieve eye fatigue.
5. Driver’s protective glasses
The principle of the driver’s protective glasses is to use the special film on the glasses to reflect the strong light hitting the glasses back to protect the eyes. It can protect against ultraviolet, infrared and blue light in foggy and rainy days. In snowy weather and at night, the wearer can see the scenery more clearly, and it can also increase the vividness of red, yellow, green, white and other colors, and eliminate the glare and reflected light of the oncoming cars when meeting cars at night.
6. Sports goggles
With the improvement of people’s sports concept and sports protection concept, sports goggles are also widely welcomed. Safety glasses worn during sports must have safety (PC lenses), protection (TR-90 frame, soft and flexible), comfortable (non-slip nose pads and foot covers), and beautiful (match sports and leisure clothing) Four major functions.
Sports goggles with shatter-resistant plastic lenses and side shields can prevent balls or sand from hitting the eyes. It can be fixed on the head without worrying about falling off during intense movements. The unique frame wrapping design makes the glasses very close to the human face and has the right isolation effect to make the human eyes less likely to be invaded by bacteria. The special lens has the functions of anti-fog, anti-impact and ultraviolet rays, which is very suitable for outdoor activities.
7. Goggles for gas welding
The colorants used in this lens are mainly iron oxide, cobalt oxide, etc., which are yellow-green in color and can absorb all light waves with wavelengths below nm. The transmittance of visible light is below 1%, and only a small amount of infrared can pass through. This eye is specially designed for welding in gas welding operations.
8. Safety goggles for welding
Ultraviolet rays generated by electric welding can cause damage to the cornea and conjunctival tissues when irradiating the eyeball for a short time (28nm light is serious). The strong infrared rays produced can easily cause opacity of the eye lens. Welding goggles can block the above infrared and ultraviolet rays very well. This kind of lens is based on optical glass, uses iron oxide and cobalt oxide and other colorants, and also adds a certain amount of cerium oxide to increase the absorption of ultraviolet rays, and the appearance is green or yellow-green. It can block all ultraviolet, infrared, infrared transmittance <5%, and visible light transmittance is about 0.1%.
9. Blue goggles
There are two kinds of this kind of glasses, one is colored iron oxide and cobalt oxide, and the filament is purple red with it, and the other is colored with copper oxide and manganese oxide, and the filament is white with it. They can all absorb the dazzling glare in the 500-600nm (visible light sensitive area of the human eye) wavelength band, the light transmittance at 400nm is below 12%, and it also has a certain absorption effect on ultraviolet rays, which is suitable for various industrial high-temperature furnaces. Personnel wear.
10. Crimson glass glasses
This kind of spectacle lens is a deep red glass colored with cadmium sulfide and cadmium sulphur selenide, which can absorb all light with a wavelength below 600nm. It can be used as goggles for medical or industrial personnel operating X-ray fluoroscopy equipment.
11. Laser protective glasses
There are two forms of this kind of glasses, namely reflective and absorptive. The surface of the former adopts a vacuum coating method to coat a layer of metal film, and the reflectivity of the laser bands with wavelengths of 532nm, 694nm and 1060nm is greater than 99.5%; the latter lens is for 1060nm The band laser can absorb all of it. The lens must be equipped with a closed or semi-closed frame to prevent the laser from bypassing the lens and entering the eye. It can be used as protective glasses for laser operators.
