These days, with the development of the Internet, each of you spends a lot of time with tablets and smartphones and computers and laptops. Physicians call the set of visual signs and symptoms that result from working with these devices Computer Vision Syndrome, or CVS for short.
If you also have problems with your eyes and vision while working with a computer, read on, in the following, we will introduce you to CVS and computer vision syndrome symptoms.
The eyes are very sensitive and delicate organs, long-term exposure to light emitted from personal computer monitors, laptops, tablets and smartphones will definitely cause pain in this sensitive organ.
Today, a large number of patients referred to ophthalmology offices are CVS patients.
How familiar are you with CVS?
Do you know the symptoms of CVS? The discomfort you feel in your eyes may have been caused by CVS.
Statistics and CVS
Seventy-five percent of people who constantly and for a long time sit in front of the computers, laptops, tablets and mobile phones suffer from this syndrome.
These days, despite the covid 19 and quarantines and the boom in telecommuting, the number of computer users and laptops has increased, and therefore we are witnessing more and more conflicts with CVS.
What are the symptoms of CVS?
The most important symptoms of CVS will be as follows:
- Dry eye:
This symptom is felt on the surface of the eye with the need for constant blinking and foreign body sensation.
- Eye fatigue:
The sufferer feels that there is a lot of pressure and weight on his/her eyes and he/she cannot continue working with the computer as before and he/she tends to close his or her eyes.
- Eye irritation
- Blurred Vision
- If you are a regular computer user, you should know that the above symptoms often present with shoulder pain: shoulder pain and neck pain.
Our eyes are the ones that see the typefaces better than the ones on the computer monitor or on the laptops.
Typefaces with white background have more contrast so they will look better and have sharper and clearer edges.
The letters on the monitor screen are not like this. These letters start from a high-contrast center and gradually fade to reach the margins and edges, where they disappear as they turn pale gray.
And this is because the letters on the monitors and tablets and laptops and mobile phones do not have sharp and clear edges and margins. This is the cause of pressure on the eyes in order for us to see and read the letters.
On the other hand, regular computer users generally reduce the number of times they blink when working with the monitor.
the eye that focuses on letters and work on the monitor for a long time will blink less, so the eyes will stay open longer, and the long-term exposure of our eye surface to ambient air causes moisture on the surface of the eye to evaporate and the surface of the eye to dry. This process is considered to be the main cause of dry and irritated eyes in regular computer users.
What should we pay attention to in order to reduce the symptoms of CVS?
If you are a regular user of monitors and computers and you suffer from the above symptoms, you have CVS, to reduce the amount of eye damage after working with the monitor and to reduce the symptoms of CVS, pay attention to the following points:
- The distance between your eyes and the monitor should be fifty to sixty centimeters.
- Use copyholders so you do not have to constantly change the position of your eyes.
- Position your monitor so that direct light does not shine on the monitor.
- Pull the curtains and reduce the brightness of your workplace.
- The desk lamp should not shine on the monitor.
- Eye fatigue increases when the screen is darker and blackened.
- Radiation of light on the monitor reduces contrast and increases the fatigue of your eyes.
- Use filter screens on the monitor.
- The center of your monitor should be ten to twenty centimeters below your eyes, this allows the eyelids to cover a wider area of your eyes and prevent further dry eyes.
- Your forearm should be parallel to the ground when working with the keyboard.
The brightness of the monitor should match the brightness of your work environment. One way to adjust the brightness of the monitor is to look at a white background. If the whiteness of the screen is like a light source for you, you should decrease the light of the monitor and if the screen looks gray, you should increase the monitor light. The contrast of the monitor should be maximum so that the edges of the letters find the maximum contrast with their writing.
Refresh rate, Dote pitch and resolution, determine the quality of the image displayed on the monitor. Be careful in setting these factors.
What to do if you have CVS?
If you have CVS, be sure to wear special glasses while working.
We need our average vision when working with a computer. A vision that we do not use in normal work, in spectacled people, their spectacle scores are not adjusted for average vision, so they should see a doctor to receive appropriate glasses for average vision.
Do not squat while working on the back of the computer, Keep your shoulders back and your neck straight. The back of the chair should fit snugly against your back.
The height of the chair should be such that your knees are at ninety degrees and the soles of your feet are on the floor.
The keyboard and mouse should be below your elbow and close to your hand.
If your eyes get tired and heavy when working with computers, tablets and mobile phones, be sure to see an ophthalmologist.
