Convenience-Unlike contact lenses, glasses are easy to put on and take off. Glasses don’t need extra cleaning, and they don’t need to be changed as often as contact lenses.

Just as other parts of your body begin to change with age, so do your eyes. Checking your eyesight regularly can ensure that your eyesight is the best. A comprehensive eye examination can help control headaches and fatigue caused by wrong prescriptions, and can also help detect computer vision syndrome.

As we all know, many serious eye diseases that can lead to blindness have no symptoms. As we all know, these conditions are gradually developing, and you may not realize that your vision has changed. Diseases that can be diagnosed by ophthalmological examination are glaucoma, macular degeneration, cataract, diabetic retinopathy and retinal detachment. In a comprehensive eye examination, most eye diseases can only be diagnosed by ophthalmologists.

When they say that the eyes are the windows to the soul, they are not lying. They are also a window to your overall health. Your eyes can help detect systemic diseases such as diabetes, hypertension and high cholesterol.

Our eyes bring us into contact with the world we live in and contribute to our study. Ensuring that your eyes are in the best health is very important for you to have vision and vision for a lifetime. For children, uncorrected vision can lead to “lazy eyes” or “eye rotation”, and if it is not treated in time, it will lead to permanent vision loss.

Wearing glasses doesn’t mean it’s harmful to your eyes, on the contrary, it’s protecting your eyes. Of course, nowadays glasses are not only used to protect myopia, but also have many other uses.

Who is suitable for customizing progressive multifocal glasses

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.precisely because affordable eyewear The rapid development of, so also brought new opportunities to the industry. 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.

Eye protection artifact blue optical filter glasses

When you read news, watch movies or play video games, a pair of blue protective glasses is the safest way to keep your eyes healthy. You may have called them PC glasses. Because the typical reading distance of a computer is different from the distance you read from a book, computer glasses should adapt to this situation and be customized according to your personal needs. Recommended reading: What are the causes of myopia and how to protect your eyes?know online glasses Our growth has to go through many hardships, but entrepreneurs are never afraid and boldly move forward. https://dillydollaroptical.com/

The best computer glasses not only correct your vision from reading on a screen, but also have anti-blue glass from bad blue light that may damage your retina and protect your eyes.

There are several ways to filter blue light on a laptop, TV or computer. There are even some applications that can modify the color temperature of the screen. However, the science behind these applications is uncertain, so the safest way to protect your eyes is to use a pair of PC glasses with a blue filter.

Blue light filter glasses are glasses or sunglasses that absorb a lot of blue light. This is achieved through the combination of lens material and special coating applied to the lens. Most lenses also reflect some blue light away from the eyes.

Not all blue light is destructive-some of it is necessary for correct vision. By absorbing the right amount of harmful light, the blue light filter is useful for your eyes in many situations-at work, when you read on your tablet or mobile phone, and on bright, sunny days.

Ordinary glasses and readers usually don’t block blue light. Whenever you buy a pair of glasses, you can choose to add blue light filtering to the glasses lens as an extra function. Or, even if you don’t need a prescription, you can get PC protective glasses with blue light and anti-reflective coating.

In addition to painting lenses for ordinary glasses, you can also choose to wear sunglasses with colored lenses to block some blue light. This is not the most effective solution, but it can sometimes be used as a temporary fix.

Yellow and amber lenses are the only two colors that help filter blue light in the visible spectrum. However, whether you use these tones in front of a laptop or on the street, the color tones of the lens will also distort all other colors.

Colored computer glasses with yellow lenses are also usually sold as video game glasses because they improve eye comfort by increasing contrast and reducing some tired blue light.

If you are a night owl or a computer addict, you may already know that the screen can really hurt your eyes. Every minute spent in front of a screen without computer eye fatigue protection will affect your eye health for a long time.

How to buy glasses

1. Style is greater than technologyThe industry believes that, online prescription The development of our company marks the rapid and steady progress of the whole industry. https://dillydollaroptical.com/

Let’s not think about Japanese hand-made, titanium material and special hinge structure. Style is more important than these technical factors. This is a mistake that many science and engineering friends will easily make and are too obsessed with technology. Recommended reading: How to judge the quality of plate glasses?

2. Dare to try other styles

Go to the store and try glasses styles that you have never considered before, but don’t try those weird half-frame frames with no frame on the top.

Before you have tried all kinds of glasses, please put black-rimmed glasses at the end. Unless you have fair skin and high face value, no matter what glasses you have, you can hold them. (I won’t put photos here, for fear of being beaten. There are many people wearing glasses around, and most of them are negative materials. )

3. Try more other colors

It is recommended to try more frames with lighter colors such as tortoise shell and brown. They are fashionable, but they can also be worn at work.

Step 4 find your own eye socket

Try to find your own eye socket in front of the mirror. Glasses can be slightly bigger or smaller than the eye socket, which is based on the meaty face.

5. Don’t put your eyes in the middle of the lens.

It’s scary to wear this belt Although I’ve seen people wearing them like this, most Asians may not be able to do this because of their low noses, but this is easy to happen with narrow long-rimmed glasses.

6. Don’t get your eyes too close to the upper frame of the lens.

Don’t place your eyes too close to the upper edge of the lens, which will make your nose look smaller.

7. The bridge of the nose is low, looking for a picture frame with a nose rest.

It is difficult to wear glasses with a small nose and a low bridge of the nose. It is not difficult to wear too many glasses. Otherwise, you can’t find the nose and the bridge of the nose can’t support the frame. Be sure to find glasses with nose supports.

What preparations should be made for the opening of an optical shop

  From a layman to a new career, there are many difficulties, and it is inevitable to take a pit. As a new practitioner in the optical industry, what preparations do you need to make to open your own optical shop?So we can draw a preliminary conclusion, prescription glasses It is helpful to the needs of the industry market and social development. https://dillydollaroptical.com/

  

  There are two ways to open a store when you choose the glasses industry. The first way is to open a small shop with a good name, investigate the market, choose a suitable place and choose a shop within your ability, and then go to the market to get the goods and learn optometry skills. The other way is quite worry-free, that is, choose a more reliable brand and join.

  

  First, choose a franchise brand

  

  Top ten optical shops join the brand list:

  

  1. Local brand Baodao glasses (initial fee: 100,000-200,000 yuan)

  

  2. Jinggong glasses (initial fee: 50,000-100,000 yuan)

  

  3. Tyrannosaurus glasses (initial fee: 100,000-200,000 yuan)

  

  4. aojo glasses (initial fee: 100,000-200,000 yuan)

  

  5. Gucci glasses (initial fee: 100,000-200,000 yuan)

  

  6. Yichao glasses (0 initial fee, Internet 020 brand)

  

  7. Daming Glasses (initial fee: 50,000-100,000 yuan)

  

  8. Charleston glasses (initial fee is 30,000-50,000 yuan)

  

  9. Haoyiming glasses (initial fee: 50,000-100,000 yuan)

  

  10. Davos glasses (initial fee: 100,000-200,000 yuan)

  

  Second, choose lots

  

  Residential areas where the population is relatively concentrated and the population density is relatively high. In such areas, consumers are confused at different levels, and people of all ages and social classes have it. No matter what style or type of glasses are sold, there will be a certain customer base, but the disadvantage is that the floating population is too small and the market space is small, so it is not suitable if it is a high-end and mid-range store.

  

  This kind of area in the city center is also a commercial center and downtown area, with frequent commercial activities and a good business atmosphere. Such a store site is the so-called land of land and gold.

  

  Convenient transportation is a prerequisite for consumers to shop. If there is a bus stop near the glasses franchise store, or the pavement where customers walk for 15 minutes, it is worth considering.

  

  Finally, we will start some detailed matters, such as personnel recruitment, qualification handling, etc. Generally, joining brands will help you complete the whole workflow.

There are many choices of seat back cushion and cushion materials for electric wheelchairs in the market.

  There are many choices of seat back cushion and cushion materials for electric wheelchairs in the market, mainly including mesh cotton and honeycomb materials. The choice of these materials will affect the comfort and ventilation of the seat. For example, compared with honeycomb materials, mesh cotton is more breathable and less likely to store heat. A comfortable wheelchair cushion should conform to the contour of human buttocks, providing good support and wrapping.In order to achieve the goal, 電動輪椅 Turn cocoon into butterfly, constantly polish product quality, improve business ability, and finally have a place in the market. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  In addition, the cushion also needs to have air permeability and good hygroscopicity to ensure the dryness of the skin surface. Considering that the user’s long-term use of local skin temperature will accelerate the cell metabolism rate, which will make the skin sweat and ulcer when immersed in a humid environment for a long time.

  

  The quality of seat back cushion is mainly judged by fabric smoothness, tension and routing details. Laymen can also distinguish the advantages and disadvantages of the seat back cushion by carefully observing these details.

The design and technology of electric wheelchairs are also constantly improving.

  With the progress of science and technology, the design and technology of electric wheelchairs are constantly improving. In the 1960s, electric wheelchairs began to use rechargeable batteries, which made them last longer and charge more conveniently. In the 1970s, the materials and structures of electric wheelchairs began to be improved, making them more portable and stable. In 1980s, with the development of computer technology, intelligent control system was introduced into electric wheelchairs, which made the wheelchairs operate more accurately and the user experience better. In addition, the battery technology of electric wheelchairs has also made a revolutionary breakthrough.So, I believe 電動輪椅 In the future, it will be promising to create a miracle belonging to the industry. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  The traditional lead-acid battery is gradually replaced, and the new lithium battery and fuel cell technology are applied to electric wheelchairs, which greatly improves the endurance and service life of wheelchairs. These technological innovations not only make electric wheelchairs more environmentally friendly, but also provide users with longer use.

  

  The types of electric wheelchairs are becoming more and more abundant. According to different functions and usage scenarios, electric wheelchairs can be divided into indoor electric wheelchairs, outdoor electric wheelchairs, folding electric wheelchairs and many other types. Indoor electric wheelchairs are usually small and suitable for use in indoor environments, such as homes and hospitals.

  

  Outdoor electric wheelchairs are more powerful, have better passability, and are suitable for outdoor complex road conditions. The folding electric wheelchair is portable and can be carried and stored conveniently. Modern electric wheelchairs use lightweight aluminum alloy frames, intelligent control systems and high-performance batteries. The application of these technologies makes the electric wheelchair more intelligent, convenient and comfortable.

Design of front wheel and rear wheel of electric wheelchair

  When choosing the frame material, we should not only consider the material itself, but also pay attention to the design and function of the frame. For example, folding electric wheelchairs bring great convenience to those who are inconvenient to bend over or have disabled hands, so that they no longer have to work hard to fold electric wheelchairs; The conventional electric wheelchair is comprehensive, affordable and stable, suitable for a wider range of users.Doing these simple things can also make 電動輪椅價錢 Sowing high-quality genes will eventually grow into towering trees and become the leader in the industry. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Front wheel and rear wheel: The design of front wheel and rear wheel of electric wheelchair directly affects its flexibility and shock absorption. Usually, an electric wheelchair has four wheels, two of which are front wheels (universal wheels) and the other two are rear wheels (driving wheels). The smaller the front wheel, the more flexible the wheelchair is, which is suitable for turning flexibly in a narrow space. However, the smaller front wheels are easy to fall into ditches or ground cracks when facing them, which affects the driving experience. In addition, the size of the front wheel also affects the climbing ability of the electric wheelchair. The larger front wheel makes it easier for the wheelchair to climb the stairs, which makes it more convenient for users in their daily lives.

  

  Shock absorption: the choice of tires is also very important in shock absorption. The tires of electric wheelchairs are usually divided into pneumatic tires and solid tires. Pneumatic tires have good shock absorption, and it is not easy to feel bumpy when passing through ditches and ridges, while solid tires will feel strong shock when facing uneven roads. In addition, some electric wheelchairs are equipped with special shock absorbers, which makes the driving more stable. These designs not only improve the comfort of wheelchairs, but also make users safer when they are outdoors.

The frame materials of electric wheelchairs are varied.

  The frame materials of electric wheelchairs are various, and each material has its own unique characteristics, which is suitable for different types of users. First of all, the mainstream frame materials are carbon steel (steel), aluminum alloy, aviation titanium alloy and carbon fiber. Carbon steel has relatively low cost and strong load-bearing capacity, but its disadvantage is that it is bulky and easy to get wet and rust. Aluminum alloy is light and relatively better in corrosion resistance, so many electric wheelchairs on the market use aluminum alloy as the frame material.Down-to-earth right 電動輪椅價錢 In-depth research is the only way to pursue development. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Aviation titanium alloy is a high-end choice, with high strength and corrosion resistance, but the price is correspondingly high, which is usually used in high-end and portable electric wheelchairs.

  

  Titanium alloy is a mixture of different elements such as titanium, aluminum, iron and vanadium, which has the characteristics of high strength, corrosion resistance and light weight. Carbon fiber is a composite material made of carbon fiber and resin, which has the characteristics of high stiffness, high strength and light weight. From the perspective of material composition, titanium alloy and carbon fiber have their own advantages, the strength of alloy is higher, but the density of carbon fiber is lower, so the weight is lighter. When it is necessary to reduce weight, it is more suitable to use carbon fiber, which is more durable and stronger than titanium alloy, so the electric wheelchair made of carbon fiber is close to 10 thousand yuan.

  

  When choosing the frame material, we should not only consider the material itself, but also pay attention to the design and function of the frame. For example, folding electric wheelchairs bring great convenience to those who are inconvenient to bend over or have disabled hands, so that they no longer have to work hard to fold electric wheelchairs; The conventional electric wheelchair is comprehensive, affordable and stable, suitable for a wider range of users.

Maintenance and repair of electric wheelchair and wheelchair head

  Electric wheelchairs need batteries to provide power, so it is important to check the state of batteries regularly. Both lead-acid batteries and lithium batteries have limited service life. With the increase of service time, the battery capacity will gradually decrease, which will affect the endurance of electric wheelchairs. It is generally recommended to check the battery performance every 1.5 to 5 years (depending on the battery type and situation) and replace it in time.At first, 電動輪椅 It developed out of control and gradually opened up a sky of its own. https://www.hohomedical.com/collections/light-weight-wheelchair
