Maintenance knowledge of radiation protection glasses:

1. Wear glasses: Please hold the temples with both hands and take them off in the parallel direction on both sides of your cheeks. If you take it off with one hand, it will destroy the left-right balance of the mirror frame and cause deformation.

2. Rotation method: If the glasses are temporarily placed, please put the convex surface of the glasses upward. If you put the glasses with the convex surface facing down, it will wear out the lenses.

3. The way to wipe the lens: use a clean special test cloth, and be sure to hold the edge wire of the lens frame on one side of the wiping mirror by hand and gently wipe the lens. Avoid damage to the frame or lens caused by excessive force.

4. When the lens is stained with dust or dirty things: it is easy to wear the lens by dry cleaning. It is recommended to rinse it with water and then use a paper towel to absorb the water and then dry it with a special glasses cloth. When the lens is dirty, it is recommended to clean it with low-concentration neutral lotion, and then rinse it with clear water to dry it.

5. Please use the glasses case: when you don’t wear glasses, please wrap them in glasses cloth and put them in the glasses case. Please avoid contact with corrosive substances such as insect repellent, toilet cleaning products, cosmetics, hair gel, medicines, etc. when storing, otherwise it will cause deterioration, deterioration and discoloration of lenses and frames.

6. The folding frame should start from the left: most of the frames of radiation protection glasses are designed by folding from the left temple, so if the right temple is folded first, it is easy to cause the deformation of the frame.

7. When the glasses are deformed: the deformation of the frame will cause a burden on the nose or ears, and the lens is also easy to loosen. It is recommended to go to specialty store for plastic surgery on a regular basis.

Small coup to prevent computer radiation:

The first trick: when operating the computer, it is best to install a computer-specific color filter on the display screen to reduce the harm of radiation, and do not place miscellaneous metal objects indoors to avoid the re-emission of electromagnetic waves. When using a computer, it is necessary to adjust the brightness of the screen. Generally speaking, the greater the brightness of the screen, the stronger the electromagnetic radiation, and vice versa. However, it should not be too dark, so as not to affect the effect because of the low brightness, and it is easy to cause eye fatigue.

The second trick: the location of the computer is very important. Try not to let the back of the screen face people, because the computer has the strongest radiation on the back, followed by the left and right sides, and the front of the screen has the weakest radiation. The distance between the eyes and the screen should be based on legibility, but it should be at least 50 cm to 75 cm, which can reduce the harm of electromagnetic radiation.

The third measure: pay attention to indoor ventilation. Scientific research has confirmed that the computer screen can produce a carcinogen called dibenzofuran bromide. Therefore, it is best to install a ventilator in the room where the computer is placed. If not, pay special attention to it when surfing the Internet.

The fourth measure: you should buy new computers as much as possible, and generally don’t use old computers. The radiation of old computers is generally severe, which is generally 1-2 times that of new computers under the same distance and similar models.

The original intention of progressive multifocal lens design is to provide a natural, convenient and comfortable correction method for presbyopia patients. Wearing progressive lens is like taking pictures with a camera. A pair of glasses can not only see far away, but also see near and middle distance objects. Therefore, we describe progressive lenses as “lenses that can zoom”. After wearing them, a pair of glasses is equivalent to using more glasses.Before that, Optical frames The market has also soared for a time, which has attracted the attention of a wide range of investors. https://dillydollaroptical.com/

Recommended reading: fitting progressive lenses for middle-aged and elderly people, you should first understand these problems!

As they get older, mirror friends will find that their eyes are good, but they are not nearsighted. After 45 years old, they can’t see clearly when they read books, newspapers and mobile phones, or they feel tired after reading for a while, so they need reading glasses. At the same time, the mirror friends who used to wear myopia glasses also found that it was no problem to read books, newspapers and mobile phones with glasses. After the age of 45, they had to take off their glasses to see clearly. This is because with age, the adjustment ability of the lens of the eye to regulate muscle aging has decreased, which is called presbyopia.

After presbyopia, you will face a problem.

1. People who are not nearsighted

You need to wear reading glasses when you are near, and you need to take them off when you are far away. If it is necessary for teachers or some jobs, you have to put them on-off-put them on-off again, which is very inconvenient. You often need to carry reading glasses with you, and you have to put several pairs of reading glasses everywhere in your home office. Because you take them off once, you often throw them around and they are crushed, and sometimes you can’t find them.

2, people with myopia.

There are two kinds of people with myopia.

One is within 400 degrees of myopia. This kind of moderate and low myopia can be seen by directly taking off your glasses when you are near, and then putting on your glasses when you are far away, and you should keep putting on-taking off-putting on-taking off again.

The other is that if the myopia degree is more than 500 degrees, or even thousands of degrees, you should also take off your glasses, but after you take them off, you can see them very close to your eyes. For example, if you look at your mobile phone, you must put it next to your eyes. This is because there is too much difference between the eyes and the head-up state after taking off the glasses. Generally, reading a newspaper or a mobile phone is about 33cm away from the eyes, which requires an adjustment force of +3.00DS, that is, it is just in the head-up state when the myopia is reduced by 300 degrees. When the myopia is reduced to offset too much, the distance will be reduced before you can see. This situation will be more troublesome than the first two feelings.

Progressive multifocal lenses, also known as progressive lenses, have multiple focal points on one lens. According to the focus, lenses can be divided into monofocal lenses, bifocal lenses and multifocal lenses. Our most common lenses are monofocal lenses, which have only one luminosity; Bifocal lenses are bifocal lenses, which were used by many elderly people to solve the problem of seeing far and near at the same time, but because of their own major shortcomings and the popularity of progressive multifocal lenses, bifocal lenses have been basically eliminated; Multifocal lenses, as a milestone in the history of lens development, will also be the main direction of research and development and market popularization for scientists in the future.

Nowadays, scientists have made corresponding research on multifocal lenses according to the eye use and physiological characteristics of people of different ages, and finally they are divided into three categories:

1. Juvenile myopia control lens-used to slow down visual fatigue and control the development speed of myopia.

2. Anti-fatigue lenses for adults-for teachers, doctors, people who use computers too much at close range, so as to reduce the visual fatigue caused by work.

3. Progressive film for middle-aged and elderly people-used for a pair of glasses for middle-aged and elderly people to see far and near easily.

　　IntroductionToday, people are interested in sofa cushion manfacturer There are also many dependencies, and the expectations for products are getting higher and higher. https://www.jopalic.com/

　　In today¨s society,sustainable development has become an important direction for the development of various industries,and the field of household goods is no exception.As a common household item,the road to sustainable development is not only related to environmental protection,but also closely related to the long-term development of enterprises and the healthy life of consumers.As a professional sofa cushion manufacturer,Jopalic has always been at the forefront of the industry and is committed to promoting the sustainable development of plush sofa cushions.This article will explore the specific performance and far-reaching significance of fleece-lined sofa cushions in terms of sustainable development in 2025,and show Jopalic¨s professional contribution in this process.?

　　Jopalic.com | The road to sustainable development of plush sofa cushions

　　Sustainable sourcing of raw materials

　　(1)Selection of natural fibers

　　Advantages of natural short plush

　　In 2025,the surface material of the plush sofa cushion tends to use more natural short plush.For example,short fleece derived from natural wool has a renewable source and the wool has less impact on the environment during growth.Compared with synthetic fibers,natural wool short plush has better heat retention and air permeability,which can provide consumers with a more comfortable experience.At the same time,the production process of natural wool is relatively environmentally friendly,reducing the use of chemicals and reducing pollution to the environment.?

　　With many years of professional experience in the field of sofa cushion production,Jopalic has established long-term stable cooperative relations with high-quality natural wool suppliers.We strictly control the quality of wool to ensure that every batch of natural short plush used in the production of fleeced sofa cushions meets high quality standards,bringing consumers both comfort and environmental protection products.?

　　Exploration and application of plant fiber

　　In addition to natural wool,some plant fibers have also begun to be used in the production of fleece sofa cushions.Like bamboo fiber,bamboo grows quickly and is a sustainable resource.Bamboo fiber has antibacterial,antibacterial,anti-mite,deodorant and anti-ultraviolet functions,which is very attractive for consumers who focus on healthy living.Moreover,the processing process of bamboo fiber is relatively green and environmentally friendly,reducing the negative impact on the environment.In addition,hemp fiber also because of its toughness,breathability and other characteristics,gradually emerged in the production of velvet sofa cushions.Hemp plants require less water in the growth process and have low requirements for land fertility.They can grow on relatively barren land and effectively reduce the occupation of cultivated land resources.?

　　As a professional manufacturer,Jopalic has a professional research and development team,constantly exploring the application of plant fibers in the production of sofa cushions.We cooperate with scientific research institutions to deeply study the characteristics of bamboo fiber and hemp fiber,optimize the processing technology,so that it can be better applied to the fleece sofa cushion,and provide consumers with more environmentally friendly and healthy choices.?

　　(2)Sustainable selection of sponges

　　The rise of biobased sponges

　　In the selection of the middle layer filling material sponge for sofa cushions,bio-based sponges have been widely used in 2025.Traditional sponges are mostly made from petrochemical products,while bio-based sponges are made from renewable biomass resources,such as vegetable oil,starch and so on.Bio-based sponges not only have similar resilience and support to traditional sponges,but also reduce the dependence on non-renewable resources such as oil and reduce carbon emissions in the production process.At the same time,the biodegradability of bio-based sponges after waste is also better than that of traditional sponges,and they can gradually decompose in the natural environment,reducing the accumulation of garbage.?

　　Keen to capture this industry trend,Jopalic is the first to introduce bio-based sponges in production.We cooperate with professional bio-based sponge manufacturers to ensure the quality and performance of our products.Through a strict quality inspection process,we ensure that every fleece sofa cushion using bio-based sponges can provide comfortable support for consumers and practice the concept of sustainable development.?

　　Promotion of recycled sponges

　　Recycled sponges are also an important direction for sustainable development.By recycling waste sponge products,after a series of processes such as crushing,screening,bonding,etc.,the sponge material with certain properties is remade.The use of this recycled sponge not only effectively solves the problem of waste sponge treatment,reduces the pollution to the environment,but also reduces the energy consumption and raw material demand in the production process of new sponge.In 2025,more and more fleece sofa cushion manufacturers began to use recycled sponges as filling materials,promoting the sustainable development of the industry.?

　　Jopalic,as the industry leader,actively promotes the application of recycled sponges.We have established a sound procurement channel for recycled sponges and cooperated with reliable recycled sponge suppliers to ensure the quality of raw materials.At the same time,our production process has been continuously optimized,which can give full play to the performance advantages of recycled sponge,create high-quality fleece sofa cushions for consumers,and contribute to the cause of environmental protection.?

　　(3)Sustainable innovation of non-slip bottom materials

　　Application of environmentally friendly rubber particles

　　For the anti-slip particle design of the bottom layer of the plush sofa cushion,in 2025,environmentally friendly rubber particles have become the mainstream choice.These environmentally friendly rubber pellets are usually made from recycled tires or other rubber products.Compared with traditional chemical synthetic anti-skid materials,the production process of environmentally friendly rubber pellets is more environmentally friendly,reducing energy consumption and chemical emissions in the production of new rubber.Moreover,the recycling of rubber products such as waste tires effectively solves the problem of the disposal of a large number of rubber wastes and realizes the recycling of resources.?

　　Jopalic has extensive experience in the application of environmentally friendly rubber pellets.We cooperate with professional rubber recycling companies to ensure the quality and stability of environmentally friendly rubber pellets.Through continuous optimization of the production process,the environmentally friendly rubber particles are perfectly combined with the bottom of the sofa cushion,which not only ensures a good anti-slip effect,but also meets the requirements of sustainable development.?

　　Research and development of natural anti-slip materials

　　In addition to environmentally friendly rubber particles,some companies are also developing natural non-slip materials.For example,ingredients with anti-slip properties extracted from natural plants are applied to the bottom of sofa cushions after special treatment.This natural non-slip material is not only environmentally friendly,but also harmless to the human body,which meets the dual needs of consumers for health and environmental protection.Although there are still some challenges in terms of cost and performance stability,this kind of natural anti-slip material is expected to be more widely used in the future with the continuous progress of technology.?

　　Jopalic¨s R&D team is actively engaged in the research and development of natural anti-slip materials.We cooperate with universities and scientific research institutions to study the anti-slip properties of natural plants and explore the best extraction and application processes.Despite the many challenges,we firmly believe that through continuous efforts,we can bring more environmentally friendly and healthier anti-slip solutions for fleece-lined sofa cushions.?

　　Energy saving and emission reduction in the production process

　　(1)Optimization of energy utilization

　　Solar and wind energy applications

　　In 2025,many fleece sofa cushion manufacturers began to actively use clean energy such as solar and wind power.The company installs solar panels on the factory roof and uses solar photovoltaic power generation to provide part of the power support for the production process.At the same time,some enterprises located in areas rich in wind resources will also build small wind power facilities.Through the use of solar energy and wind energy,it not only reduces the dependence on traditional fossil energy,reduces the energy cost of enterprises,but also greatly reduces carbon emissions,and plays a positive role in environmental protection.?

　　As a pioneer in the industry,Jopalic has been laying out the use of clean energy for many years.We install solar panels on a large scale in the factory to make full use of solar energy resources.At the same time,for some factories located in areas suitable for wind resources,we are also actively preparing for the construction of small wind power generation facilities.In this way,we not only reduce production costs,but also make a positive contribution to reducing carbon emissions,demonstrating the environmental responsibility of professional sofa cushion manufacturers.?

　　The introduction of energy management systems

　　In order to further improve energy efficiency,the company has introduced an advanced energy management system.The system can monitor the energy consumption in the production process in real time and optimize the operation of the production equipment through data analysis and intelligent control.For example,according to the weight of the production task,the power of the equipment is automatically adjusted to avoid the waste of energy.At the same time,the energy management system can also predict energy demand and allocate energy in advance to ensure a stable and efficient energy supply for the production process.?

　　With its own technical strength,Jopalic independently developed and introduced a set of energy management systems suitable for the production of sofa cushions.The system can accurately monitor the energy consumption of each production equipment,and realize intelligent regulation of equipment operation through big data analysis and intelligent algorithms.This not only improves energy efficiency,reduces production costs,but also provides strong technical support for sustainable development.?

　　(2)Improvement of production technology

　　Water-saving printing and dyeing process

　　The water-saving printing and dyeing technology has been widely used in the printing and dyeing process of short plush fabric on the surface of sofa cushion.The traditional printing and dyeing process uses a lot of water,and the printing and dyeing wastewater contains a lot of chemical substances,which causes serious pollution to the environment.The new water-saving printing and dyeing process adopts advanced digital inkjet printing and dyeing technology,which realizes the printing and dyeing of patterns by precisely controlling the amount and position of ink injection.This process not only greatly reduces the water consumption,but also reduces the chemical pollution of printing and dyeing wastewater because the ink used is environmentally friendly ink,which is conducive to environmental protection.?

　　As a professional sofa cushion manufacturer,Jopalic actively introduces and optimizes the water-saving printing and dyeing process.We invest a lot of money to update printing and dyeing equipment,using advanced digital inkjet printing and dyeing technology.At the same time,we work with ink suppliers to develop more environmentally friendly and more efficient inks to ensure the quality of printing and dyeing while reducing water consumption,and provide consumers with colorful,environmentally friendly and healthy plush sofa cushions.?

　　Efficient cutting and splicing technology

　　In the process of making sofa cushions,the application of efficient cutting and splicing technology also realizes energy saving and emission reduction.Through computer-aided design(CAD)and automated cutting equipment,fabrics can be accurately cut according to the size and shape of sofa cushions,reducing fabric waste.At the same time,advanced splicing technology can improve the efficiency and quality of splicing,reduce the defective rate caused by poor splicing,thus reducing the waste of resources and energy consumption in the production process.?

　　Jopalic has always focused on the improvement of the production process,and is the industry leader in efficient cutting and splicing technology.We have introduced advanced CAD design software and automatic cutting equipment,which can accurately cut according to different styles of sofa cushions.At the same time,we have trained a group of professional technical workers,skilled in advanced splicing technology,to ensure product quality and production efficiency,reduce resource waste,to achieve the goal of energy saving and emission reduction.?

According to Agence France-Presse reported on March 19, Ukraine Foreign Minister Dmitry Kuleba said on the 19th that Ukraine was shocked by the continued obstruction of a key budget plan to help Kiev resist Russia in the U.S. Congress. The plan has been deadlocked for months.

Reported that he said at an online briefing to foreign media: What is really important and shocking to us is that the decision has not yet been adopted. It is approaching the end of March, but discussions continue.

However, Kuleba believes U.S. aid will eventually come. He pointed out: This is a question of confidence in the ability of the United States to support countries that follow the rules and principles that the United States defends around the world, far beyond the scope of Ukraine alone.

The foreign minister stressed that Ukraine does not rule out Trump’s idea of providing aid in the form of loans rather than grants, but needs to know more details.

The report mentioned that the day before, Republican Senator Lindsay Graham, one of Trump’s loyal supporters, visited Kiev. He supported the former US president’s proposal to provide assistance to Ukraine in the form of an interest-free loan.

Kuleba responded: We are not shocked to hear this suggestion from the United States. We really need to study the details.

Reported that the Biden administration has been calling for months for the passage of a new Kiev aid plan, including $60 billion in military and economic aid. The plan has been approved by the Democratic majority in the Senate, but is still blocked in Congress.

Passage of the plan depends on the goodwill of Trump’s supporters in the House. Trump supporters have refused to review the current plan due to differences over U.S. immigration management. (Compiled by Zhao Kexin)
