Staring at a bright screen for hours can lead to eye fatigue or eye strain, headaches, blurred vision, burning, itching or tearing eyes, and temporary vision disorders. Fortunately, eye strain rarely results in a permanent condition and symptoms can be prevented or cured rather easily.
Use a quality display of sufficient size.
Keep at least one arm length between your eyes and your display.
Follow the 20/20/20 rule, i.e. every 20 minutes, focus on an object 20 feet (6 meters) away for 20 seconds. You can use tools like EVO or EyeLeo to remind you.
Improve the lighting in the room, particularly install bias lighting.
Use f.Lux to automatically dim your display as your room gets darker.
Computers bad for health
Emotional Pressure & Isolation Cause Anxiety & Depression
Computers are very efficient tools in that they help us with getting more work done in less time. At the same time, you spend less face-to-face time with your colleagues, family, or friends. This can lead to isolation, anxiety, and depression, i.e. both physical and mental health issues. The symptoms are manifold and can include tense muscles, back pain, headaches, poor sleep (insomnia), increased or flat breathing, quickened pulse, and generally signs of stress, depression, or anxiety.
In addition to stretching, go for a brisk walk or run up and down the stairs to work off stress levels.
During your frequent breaks, seek out social interactions.
Have meals with colleagues or friends.
Don’t forget to drink lots of water.
Plan for social activities after work.
Meditate before or after work.
Exercise before or after work.
Are computers bad for health? Too much of anything is bad for you. Working with a computer for hours on end day in day out is very straining for your body and can cause very serious health issues. Fortunately, you can avoid pain and misery with only a few simple routines. The key changes are to take frequent short breaks, get up to walk and stretch at least once an hour, actively relax, interact with other people, and especially if you have a lot of stress, remember that you must exercise to stay healthy.
How do you stay healthy while spending hours a day on the computer?
First of all, our eyes will be tired if we use computers for a long time because when we see the screen with short range(just more than 30 centimetres) . At first, there are no problems with your eyes. However, just in few more hours later, your eyes want to close. If you try to open them without have a rest, you may have a myopic. That's why computers are not healthy to humans.
I completely agree with the author's opinion that computers are not healthy for humans.
Working on the computer may sound like the most relaxed job in the world, but it’s not. It’s very tough to our body, working a long time in front of the computer.
Sitting has long been known to cause back pain, which can promote some disease. Extensive use of the keyboard and mouse can trouble the muscles in our hands, arms, and neck. Staring at a bright screen for too long can cause dry eyes and headaches.
Finally, computer work can be stressful and lead to depression and anxiety.
People with 20/20 vision is becoming more rare these days due to technology advancements. Computers hae been around for quite a long time, and a factor in worsening eyesights. When a person uses a computer, he or she is focusing on the bright screen and less on blinking. This can dry out one's eye, thus bad eyesight.
They solve problems and do complex algorithms that you cant imagine. Our traffic signals and security cameras are run by computers. Not all computers we use we see as a screen. We should still stay in contact with our friends, family, and co-workers but computers are good. MrAmazingDuck you are using computer know!!!
