What are the colors of the fishing polarizer?
Amber, yellow, or orange lenses are very suitable for wearing on cloudy days. They can have a very clear vision, but they are not suitable for use on sunny days. Gray or dark green lenses can maintain the most natural original color when viewing objects, which is a good choice. Sunglasses are not only required to be worn in summer but they must also be used throughout the year. Wear it on sunny days and also on cloudy days. Don't think that the sun is not strong on cloudy days and the weather is not hot, so you don't need to wear sunglasses. The harmful ultraviolet rays will harm your eyes unknowingly. Therefore, even if it is a cloudy day with thin clouds, you must still wear sunglasses to protect your eyes.
Acetate is a kind of thermoplastic resin obtained by esterifying acetic acid to acetic anhydride under the action of a catalyst. Acetate is resistant to water, gasoline, mineral oil, and lipids, weak alkaline solutions, and acids, excellent weather resistance, not resistant to ethanol, strong acids, and strong alkaline solutions. During thermoforming, it is very necessary to dry the material before forming. Acetate was born in the early 20th century, and was successfully trial-produced and industrialized by the UK in the early 1920s. At present, it is the second-largest variety in cellulose fiber after viscose fiber. Acetate can be used to make textiles, cigarette filters, film bases, and plastic products.
Advantages of carbon fiber glasses frames
The main reason for choosing carbon fiber to replace traditional plastic and metal materials is that carbon fiber has the characteristics of lightweight and high tensile strength. Spectacle frames made of carbon fiber materials are significantly lighter than traditional metal spectacle frames. In addition, such spectacle frames are impact resistant, has high hardness, wear resistance, are not easy to deform, and will not fade. Also, the carbon fiber material has good biocompatibility and is often used in medical equipment, so it will not cause allergic reactions, and it is not easy to corrode and rust. The lightweight carbon fiber frame is easy to carry, and it is not easy to deform the bridge of the nose when worn on the bridge of the nose, relieves the burden on the nose and ears, is not easy to slip, and is comfortable to wear.
Anti Fog Safety Glasses - Safety Goggles Over Glasses
Anti-fogging safety glasses reduce deformation, effectively prevent fogging, and avoid fogging which affects vision in use. The angle of the goggles can be adjusted in accordance with the different foreheads (30 degrees). They can use a variety of large-size myopia goggles, safety glasses. It can effectively protect eyes from saliva, sand, metal fragments, and so on.
What are polarized lenses for?
Polarized lenses contain a layer of polarizing plates in which molecular chains form a light-grating structure in which dichromatic pigments, which absorb polarized light, are evenly distributed. A beam of light is absorbed when it vibrates in the same direction as the bars of the molecular chain of the polarized lens. The grating direction formed by the molecular chain of the polarizer is the axial direction of the polarizer, which is generally horizontal. When polarized lenses are worn, they absorb all the light that vibrates horizontally, thus absorbing the glare and preventing it from reaching the eyes.
Benefits of glasses without nose pads
Glasses without nose pads are mostly used for sheet materials because the sheet material is lighter and not allergic. From the viewpoint of aesthetics and comfort, no nose pads are more suitable. Glasses without nose pads have a relatively small contact area with the bridge of the nose, so it is not easy to have obvious indentations on the bridge of the nose, while glasses with nose pads will have obvious indentations after wearing them for a long time.
In addition to supporting the frame, the nose pad has another function to prevent allergies and avoid discomfort caused by allergies to metals or other materials. Whether it is better to have glasses with nose pads or without nose pads, depends on your personal situation. If your nose is sensitive to weight or the bridge of your nose is lower, you should choose glasses with nose pads. If you are particularly looking for beauty and don't want any marks on your face, then choose glasses without nose pads.
In fact, it is hard to say which one is better between nose pads and no nose pads. The key is to look at personal preference and wearing comfort. Generally speaking, a high nose bridge is suitable for choosing frames without nose pads. It is more suitable to choose the frames with nose pads for people with flat nose bridges in order to prevent the glasses from sliding off and affecting the visual effect.
