New virus Corona at home tired of eyes April 24 20:01
When I was working at work every morning, I used to adore working from home, but when I actually started it, it seemed like I had a hard time unexpectedly. One of them is "eye strain". I covered the relationship between working from home and eye fatigue.

"No eye fatigue"
Since the declaration of an emergency in Tokyo and other areas, and the government calling the business offices, telecommuting has been rapidly progressing in various workplaces. Against this backdrop, many tweets have been posted on Twitter complaining of "eye strain" caused by working from home.
"Because I started working from home, my eyes became more and more tired. I'm seeing more and more smartphones, and I think it's straining my eyes
. " "Telework every other day. I'm looking at the small letters on my laptop. "My eyes get tired."
"What makes working at home the hardest, I feel like fighting eye fatigue ..."
"Eye fatigue due to the feeling of being at home"
"MTG is all remote. I'm tired of my eyes because it's through the LCD screen. "
Speaking of work that can be done at home, more and more work is done using a personal computer, and many of the meetings and face-to-face interactions that have been face-to-face have been replaced by screen-based ones, so the time to keep looking at the LCD screen It seems that the increase is in the background.
Also in a glasses store
“I'm getting tired from working at home, so the number of customers who want to do something is increasing
,” says Yoriko Sakata of “Sakata Glasses,” a glasses store in Gyoda City, Saitama Prefecture.
It is said that the number of inquiries came to the store around the end of March, and the number has increased since April 7 when the emergency declaration was issued.
For this reason, Mr. Sakata has advised customers to wear glasses that are easy on their eyes when they look at their computers.
Mr. Sakata:
Normally, the glasses are adjusted so that you can see things that are about 5 meters ahead, so it is common to make new glasses with a different focus to see close things such as a computer screen. Target
At this store, it seems that they were doing that at the beginning, but what stood there was "going out".
"Inspection" and "fitting" are important in making glasses. It is necessary to have customers come to the store, but the number of customers has dropped dramatically. It means that the number of sales will be halved if it remains as it is.
Somehow
So, we launched a product that focuses on another lens on the outside of the glasses. By adjusting the power with a combination of two lenses, it is possible to focus on nearby objects.
You can make it by mailing the glasses you are using.
Mr. Sakata said, "There are many people who can't come to the store even if their eyes are tired, so it would be nice if these products could solve the problem, and it would be a management crisis for the store, so it would be good to add sales. I think. "
The cause is
The tired eyes of being at home, which is often a problem.
An ophthalmologist specializing in dry eye and corneal research, I asked Professor Kazuo Tsubota, Professor, Department of Ophthalmology, Keio University School of Medicine, about the causes and precautions for working with a personal computer.
It is said that when working from home increases the time spent facing the computer, there are two main causes of eye strain.
The first is called "ciliary muscle", which is a muscle that focuses by pulling or loosening the crystalline lens of the eye to see things. It seems that he tries to focus on the computer screen at hand many times repeatedly, causing tired muscles and tired eyes.
The second point is that dry eye is the cause. This means that when you work on a computer, you stare at the screen, which reduces the number of blinks.
Professor Tsubota
"People usually blink 20 times a minute. I keep my eyes dry by blinking, but when I look at a computer, I blink only 6 to 7 times a minute. Then it becomes dry eye. ''
With dry eye, the surface of the eye becomes dry and is easily damaged. Doing so will tire your eyes.
This means that you will not lose your eyesight due to eye fatigue, but if your eyes get tired you will not only get stiff shoulders and headaches, but also work mentally, which will reduce work efficiency.
Also, the light emitted from computers and smartphones contains a lot of short wavelength and strong light called blue light, which is bad for the eyes.
Measures
He said that while working from home increased, it was important to stay in the sun without doing the same work in order to avoid eye fatigue.
Professor Tsubota
"Do not hold a web conference for an hour or two. If you work for 45 minutes like an elementary school class, be sure to take a 15-minute break to rest your eyes. If you have a terrace, it is important to be exposed to the sunlight, such as going out. Also, when working at home, it is necessary to work near the window where the light hits and sometimes open the window to work. "
And when you feel tired, it is most important to rest your eyes by sleeping.
Opportunities to face personal computers at home are expanding beyond the time of working from home such as online drinking parties and classes.
It seems that it is necessary to deal well with tired eyes to survive this emergency.
