The polarizer is manufactured according to the principle of polarization of light. We know that when the sun shines on the road or water, it directly irritates the eyes and makes the eyes feel dazzling, tired, and unable to see things for a long time. Especially when you are driving a car or engaging in outdoor recreational activities, it not only affects our work and entertainment mood, but even affects our judgment of objects and causes danger; long-term exposure to direct sunlight can also cause a rapid decline in vision. Formation of myopia, hyperopia, astigmatism or cataracts.
1. The special effect of the polarizer is to effectively exclude and filter out the scattered light in the beam. The light can be injected into the visual image of the eye on the transmission axis of the right track, so that the visual field is clear and natural. Similar to the principle of blinds, the light is adjusted to the same direction and enters the room, which naturally makes the scenery look soft and not dazzling.
2. The characteristics of general polarizers Although polarized lenses can filter out many irregular light interference and avoid glare, glare, etc., if the curvature of the lens itself cannot be in the optical optical standard refractive state, the polarization effect will be weakened. Affect the authenticity of the image, and the durability is poor. The general polarized sunglasses on the market are made of fiber sandwiched with a polarizing film. It is different from the optical glass polarized sunglasses because of its soft texture and unstable arc. After the lens is fitted with the frame, the lens is difficult to reach the optical refractive standard, and the image is loose and deformed. Due to the unstable arc bending, the lens is deformed, which directly leads to the poor clarity of the transmission image and the distortion of the image, which can not achieve the normal optical effect. And the surface is easy to scratch and wear. Not durable.
3. The ideal sunglasses should have the following important conditions:
①It must be able to filter more than 99% of the ultraviolet rays in the sun, and the filtering performance must meet the requirements of international standards
② The function of effectively blocking strong light
③ The lens has a standard optical arc design to form The visual image is produced by the optical axis of vision.
④The eye frame is firm, the frame material is excellent, and the optical function is designed. After wearing it, it feels comfortable and safe. Polarized sunglasses lens is a composite material, generally composed of seven layers, the outermost two The layer is wear-resistant, the second and sixth layers are UV-resistant, the third and fifth layers are to filter harmful rays, and the middle layer is the polarizing layer.
Polarized lenses have good anti-ultraviolet effects, but they are not abrasion resistant and easy to scratch. The polarizer can block the random reflected light, glare and irregular reflection of objects in the natural light. There are 300,000 linear molecular arrangements invisible to the naked eye in every 1 square centimeter of the polarizer, and they are arranged in the same one. direction. Compared with ordinary glass sunglasses, polarized sunglasses do not affect vision, and will not cause chromatic aberration. Long-term color contrast will affect people's perception of color. At the same time, it can effectively avoid the damage of ultraviolet rays to the eyes. Polarization principle: When light is reflected from the surface of an object, it has been partially polarized to produce glare. The opposite effect of glare-one enhances the brightness, weakens the color saturation, makes the outline of the object blurred, and makes the eyes tired and uncomfortable. Polarized spectacle lenses are made according to the principle of polarization of light. They have a unique priority to eliminate glare, and have special effects on drivers, which can improve vision and add fun to the ride. Advantages of polarized sunglasses: The reflected glare formed by sunlight on sand, water, snow, and road surfaces often causes eye discomfort and fatigue. The polarization angle and arc of polarized sunglasses are designed according to the principle of precision optics. This irregular reflected light can be effectively arranged and filtered (such as the principle of blinds). The light is arranged into the same direction and enters the eyes, making the surrounding scenery look soft and not dazzling.
