How To Choose Better Night Driving Glasses?
You should select light alloy material and polymer material with memory, collision resistance, and low friction coefficient characteristics. It can effectively prevent the damage to the eyes and face caused by the friction of the broken lens frame during use. Because of its specific molecular structure, the chemical resistance is good. In the high-temperature environment. it is not easy to deform and can withstand 350 degrees in a short time of high temperature, not easy to melt and combustion. The glasses made of this material are light and strong, and the ears will not be uncomfortable because of wearing the glasses for a long time.
Advantages Of TR90 Frames
- Lightweight. The weight is about half the weight of the plate frame, which can reduce the burden on the bridge of the nose and ears, and it is also comfortable to wear for a long time.
- Bright colors. Compared with ordinary plastic frames, the color of TR90 frames is even better.
- Impact resistance. The TR90 frame is extremely flexible, and its good elasticity can effectively prevent damage to the eyes caused by impact during sports.
Regardless of whether it is a sheet frame or a TR90 frame, they have their own advantages. You can choose them according to your requirements, Importantly, it is comfortable to wear and good-looking.
Is it true that green film prevents blue light?
Some lenses filter out harmful blue light by reflective multiplayer coating. The lens has a bright blue-violet coating. Green film anti-blue lens relies on the lens material itself to absorb blue light. Therefore, it is impossible to know if the lens can really block the blue light only by looking at the film layer. Instead, it is necessary to use the test equipment of blue light blocking rate or ask the manufacturer to provide relevant experimental data. There is no problem wearing an anti-blue lens unless the user has a high demand for color authenticity, like painters, graphic designers, etc. Because when using anti-blue glasses to see white blue objects, there will be a certain color deviation. It is up to the above workers to make their own decisions.
Progressive multifocal glasses are more powerful.
On the premise of the dual vision correction effect, the progressive lens has more stable and complete functions. They provide lasting clear vision. Because the added value is continuously and slowly increased in the related area, the wearer can get a lasting clear vision from the far place to the near place through the progressive glasses. The appearance is better than that of bifocal and trifocal lenses, and there is no subplate dividing line.
Orthokeratology lens
Orthokeratology lenses appeared in the United States in the 1960s and became mature in the 1980s. In 1996, Taiwan first imported the product, and it entered mainland China the following year. It is called OK lens for short because of its pronunciation. After OK lens entered China, it was immediately found by businessmen. A lot of institutions and individuals who do not have the relevant qualifications have flooded into the operation of the OK lens. On July 5, 2001, the State Food and Drug Administration formulated the Regulations on the Supervision and Administration of the Operation, Inspection and Matching of Orthokeratology Lens, which regulated the operating institutions and testing and matching institutions of Orthokeratology lenses. But in China, the rule did not change the course of events.
Disadvantages of polarized sunglasses
Polarized sunglasses have many benefits. However, in some cases, non-polarized lenses are a safer choice. On cloudy days, drivers find that non-polarized sunglasses are better than polarized sunglasses due to the lack of glare and extreme sunlight.
Driving with polarized lenses after snowing can be dangerous for drivers. As the glare of polarized sunglasses is blocked, ice or snow on the road will not be visible. In this case, the advantages of polarized sunglasses will become the disadvantages that may cause accidents.
In addition, when driving along a dark road with few street lights at night, wearing polarized lenses will make it harder to see the road conditions because they dim the available light better than non-polarized glasses. Of course, in low-light conditions, it is best to avoid wearing sunglasses completely while driving.
The most significant disadvantage of polarized sunglasses is that they do not perform well on digital screens and displays. They can cause the images and information on the LCD screen to blur or disappear at certain angles. Don’t wear polarized sunglasses to use these devices while driving.
Can you repair rimless glasses by yourself?
Splice the broken temple of the glasses into its original position on the glasses. Cut a piece of tape about 10cm long and pass it through the gap between the temple of the glasses and the base of the spring. Place the tape on the inside side of the glasses and tighten the other side with your hands. Then apply the outer tape to the temple of the glasses and press it down with your hand. Cut a piece of tape about twice the circumference of the bottom of the temple of the eyeglasses and stick it around the bottom of the temple of the eyeglasses. Cut a piece of tape about twice the circumference of the upper-middle part of the temple and use it to stick the top of the tape used in the first step. Then a piece of tape roughly twice the circumference of the middle leg of the glasses was used to tape the area between the two steps. Then repeat the previous step, and introduce another layer of tape from the gap on the outside of the adhesive tape. First, cut off a piece of tape as long as the temple of the glasses and stick the end of it to the bottom of the temple at an angle of about 60 degrees. Then tighten the other end with your hand, making it stick upward in a spiral until it covers all the tape in front.
