What are the signs and symptoms of computerized train? fatigue, blurry or fuzzy vision, your vision goes in and out could be double and then all of a sudden become single. You might even feel dizzy, your stomach might be a little upset. All of a sudden you can't even focus on the work you can't concentrate. headaches, including migraines can be a sudden symptom as we discussed before, dry red or irritated eyes. And here's a number one reason that I see people they're near suddenness, increased myopia.

They work on the computer a lot and every year they come in and need a stronger and stronger and stronger prescription. So working on the computer a lot can create increase in nearsightedness and I bet a lot of you who are taking this course I say oh my goodness, you're right. My eyes have gotten worse every year. I need a stronger prescription. Huh huh interesting not only know where that might come from a slower ability to focus and refocus your eyes. These are some of the possibility of the symptoms, excessive tiredness of the eyes, neck strain shoulder, upper and lower back pain and eye coordination problems eye muscle problems which can contribute to occasional double vision.

Risk factors and causes we can experience computerized train. When we sit too close to the computer. A good distance from the computer should be no closer than 18 inches. If we spend too many hours at the computer, if we blink less if we have poor posture which we'll be going over if the lighting conditions are bad. Or if the work conditions also have excessive glare like from a window. When I say if you carry 50 pounds of rice on your back, eventually your back will be bent over, because function affects structure.

If you're going to sit in front of a computer all day, again, something's going to happen to your eyes, because function will affect structure. So, like we said, let's try to monitor how much time we spend on a digital device per day. We already went through the statistics. It's kind of incredible that it's almost epidemic. What is the length of the sessions between the time that you take breaks? Where is the your device set up?

And is the ergonomics set up properly? Do you have prescription it glasses that are needed to prevent eyestrain are usually prescribed a specific type of prescription for people who work on the computer. And the number and frequency of breaks a person takes from the computer to relax his or her eyes. These are great times to do I exercises. Also, what is the type of computer screen and use? Most people use LCD or LED screens today a significant improvement over the screens of the past.

You know you hear about retinal display or regular displays Yes, different screens for different people will affect their eyes differently and you might feel more comfortable on a different type of screen. Personally, I usually use the one that has retinal display and that feels the least strain on my eyes in general, looking at monitors for To long periods of time is just not good for overall health. What can we do when we are on the screens, the contrast and Bing sentence settings matter more than the nature of the lighting efficiency. And that is something you can control on your computer LCDs have an ecological benefits and picture quality advantages, but they emit blue light that damages the retina, the circadian physiology and possibly cognitive performance. Hmm So how are we going to work with this that to come as the course goes on the text size, the size to be three times the smallest size you can read from a normal view in position 20 to 30 inches from your monitor.

So the larger the print size, the easier is on your eyes, backgrounds and colors when it comes to color, color. combinations. Your eyes usually prefer a black text on a white background or other dark on light combination. Avoid low contrast text background color schemes. Look at this chalk protect your eyes. What are the habits we want to take into consideration avoid blue light by getting special blue light glasses and also as we talk about nutrition, taking nutrition and diet that helps absorb the blue light.

Take breaks, good posture when working on the computer and avoid glare. We talked about the nutrition and lifestyle healthy diet, which we're going to talk about drink water, not sodas. We should usually drink about half our body weight in water per day, and not all at one time. So if you weigh 128 pounds, you should drink 16 four ounces of water per day, but you should drink them in, let's say four ounces at a time so you don't strain your kidneys. Not 32 ounces at a time. Use lots of antioxidants.

Take a walk, get your body moving, moving. What are the symptoms of computerized drain, dry irritated eyes, headaches, blurry vision, and just low fatigue in general. And now, the 20 2020 rule that many of you may have heard about before, so every 20 minutes, look at least 20 feet away. Hopefully you can have a window you can even look farther and 20 feet away and look away for a minimum of 20 seconds. That is my 20 2020 rule. eye problems that can be affect you on the computer.

If you have uncorrected eye problems, such as a stigmatism, farsightedness, or eye related aging issues that affect people usually over the age of 40, such as presbyopia, see your eye doctor to get the proper eyeglass prescription for computer use. Believe that anybody who's going to be working on the computer should see their eye doctor for general exam and ask them for specific glasses for the computer. Even if they don't need a prescription, getting glasses that can help absorb the blue light, and the glare will be very important. The eye problems the symptoms can become chronic and intense enough that you can even use the computer for work. I have people who say I can't even look at the computer. It just causes me pain in my eyes.

Because when our eyes get tired, two things happen. The muscles of the eyes I become tired and the surface of the eyes become too dry. And but we talked about that we don't blink enough blinking and breathing. Ah, that's good. Computer eyes training children not only can affect their eyes, look at that picture of that little toddler work on the computer. And let me set tell you that is not not.

We see people doing that all the time. So children can experience computer eyestrain and musculoskeletal disorders as a result of the computer use, especially with laptops. Because they're bending over you can see in this child's posture, how the head is in front of their body, and then the back is tilted. This extensive use for children can lead to eye tiredness, blurred vision, headaches, irritability, and an increase in eye prescriptions. The American Optometric Association reports that children have the ability to keep playing or working on the computer with great concentration and without realizing that they're even getting tired. True adults are perfectly capable of the same actions, but they tend to have more self awareness and can recognize when they when they are getting tired.
