Computers and digital screens are now an integral part of everyday life, as the average daily usage time is 6-9 hours. As of 2021, it is estimated that 84% of the world’s population uses some kind of digital screen device. This number is expected to grow further in the future.

Social disstancing policies are affecting more people in a short period of time, with an unprecedented number of adults working from home and children forced to study from home, and more and more people relying on digital screen devices for conference calls and entertainment purposes.

People experience different things through sight. It is important to take frequent breaks from the digital screen that you rely on all day and keep your eyes healthy.

Hello. Satoshi.

As long as you are working surrounded by computers, you need to keep an eye on them. More time to look at the screen is said to lead to dry eyes, eye strain, headaches, and poor visibility.

I tried to summarize the measures. The difficult things have been eliminated for the time being. Please try to reference.

The eyes are the ones to use for life. We will do maintenance on a daily and cherish it.


What is Computer Vision Syndrome?

Computer vision syndrome is a series of vision problems caused by prolonged use of digital screens, such as computers, tablets and mobile phones. Symptoms of computer vision syndrome include eye strain, poor visibility, dry eye and headaches, as well as neck and shoulder pain in some cases.

These symptoms can be caused by dim working environments, high-brightness screens, the use of poor-quality equipment, environmental and body posture, problems with naked eye vision, or all of these complex problems.

The degree of symptoms depends on the presence or absence of naked vision problems, such as farsightedness, adphoriphotity, inadequate eye focus adjustment, and age-related changes in vision, in addition to the time spent looking at the screen.

Causes of Computer Vision Syndrome

Printed matter is sharper than digital screens because the images on the screen consist of thousands of tiny pixels. This is also known as image resolution, which is prone to flickering and glare on the screen, and is prone to variations in the field of view. Therefore, reading the screen requires more concentration than print.

As a result, the eye muscles are strained to adjust the lens of the eye to constantly focus on the digital screen. This leads to an increase in eye strain and poor visibility associated with computer vision syndrome. In addition, when looking at a digital screen, the blink rate may decrease even if you squint voluntarily. I think that it may be judged that it is easy to become dry eye if the blink which is a normal lubrication mechanism of eyes is not enough.

3 preventive methods of computer vision syndrome

1. Take frequent breaks

The best way to prevent eye strain is to take a break frequently and rest your eyes to focus on the screen for a long time. There is a standard of 20-20-20 rule developed by the American Optometry Association and internationally recommended. It’s about taking a 20-second break every 20 minutes, staring at things 20 feet away and refo focal pointing your eyes.

2. Blinking is important

Anyway, let’s blink as much as possible. Blinking is a way to keep your eyes hydrated. Eye drops can also be used as a dry eye measure, but avoid eye drops that contain ingredients such as nafazoline and tetrahydrozoline to reduce eye hyperidicity. Such a component is a vasoconstrictor, which suppresses eye hypersorgidity by constricting the eye arteries that carry blood rich in oxygen necessary for eye nutrition. Prolonged use of these eye drops can result in hyper-blood ed.

3. Use appropriate lighting

If you’re willing to spend a little money, keep working in a bright room and adjust the brightness and contrast of the screen. If you work all day looking at your computer, anti-glare screen filters can reduce the amount of blue light, glare (glare) and reflections on your computer screen. Some apps reduce the amount of blue light on the screen of your digital device to relieve the burden on your eyes. But most importantly, proper environmental lighting.

Change jobs to work that does not use a personal computer.

Detailed manuals are created for each store, so it is okay if you work to protect it.

Since the main thing is to respond to customers as a customer service, it is important to work without forgetting to smile.

Line manufacturing jobs

There are few machines that use personal computers when working on a line that manufactures products in a factory that makes products.

However, machines made according to company regulations may be used in the manufacturing process of the line. However, in that case, it will not be a difficult task like a personal computer.

The work content is quite different depending on which process you enter the line, but it will still be the same process repeatedly in every process.

The important thing here is to be able to do your job accurately. As you get used to it, it tends to be a good addition and subtract, so be careful not to do so and try to continue working.

Cash register hitting such as supermarkets

Only registers will be mastered, so first of all where and which buttons are there … It is necessary to learn such.

Once you learn about it, it will be a recurring task, so it may be said that it is relatively easy.

The important thing about cash register hitting is to make sure that you hit the cash register quickly and accurately.

Security guards work hardly use computers. Guards are doing their job of keeping civilians safe.

You will be standing for a long time, and you will need to make physical strength that can withstand hot summer and cold winter seasons.

It is also helpful that there is surprisingly a lot of recruitment for the work of security guards.

Basically, people who want to keep people safe or who are “confident in their physical strength” are good for security guards. In addition, communication skills make it easier to perform smooth work.

And a little while ago, I was a man when I was a security guard, but now it’s becoming a profession where women don’t feel uncomfortable working.

Is it a little dangerous for a woman to be a security guard? There was an image that, but if you guard in a place where women work, it will be easier for women to feel very hearty.

Bakery (Branje)

If you like making bread, how about becoming a bakery? If you are a baker, you do not need to work on a computer, and it is your job to bake delicious bread every day.

However, the bakery is very early in the morning. And since you always need strength in standing work, it can be said that it is still a physical strength game work.

I love bread anyway and want to hone my skills in each new recipe and baking bread even more deliciously… It is a recommended job for people who want to do so.

Hairdresser and Nailist

Hairdressers and nailist basically don’t do pc work.

You may need a list of customers to pass by, but the main job of hairdressers and nailist is to perform treatments to clean customers.

It can be said that both are for people with a high sense of beauty. In addition, since it is essential to serve customers, communication skills and attention must not be lacking.

It is a pleasure to have customers return beautifully and satisfied with it.

As a skill to do housework agency, if you are basically doing all the housework as a housewife (even the husband is OK) on a daily day, you will be able to work without problems first.

After all, it will be a prerequisite to like cleaning and cooking to some extent because it is to do housework in people’s homes.

In addition, it can be said that it is good for people who want to “feel exhilarated about making the house beautiful” and “want to make it beautiful and please customers”.
