Dry eye and blurred vision can be a symptom of computer vision syndrome

Computer Vision Syndrome (CVS) is an eye disease that primarily affects people who spend hours in front of a computer. The main symptoms include dry eyes, blurred vision, headaches, neck pain and eye strain.

Doctor, according to an ophthalmologist. Maria Beatrice Gerios, who spends more than three hours in front of a computer, is at increased risk of developing computer vision syndrome throughout her life.

“In addition to dry eye, a person may experience redness, a burning sensation, diplopia, and other things that interfere with work performance. It is worth noting that the symptoms are beyond the ophthalmic part and are produced. It can even reduce sex, “says the doctor.

Pixels and human eyes

The description of the onset of the syndrome is related to the type of image that the eye needs to see. Images on the screen are made up of pixels, which are small dots used to measure the resolution of electronic devices. Each pixel has a bright center and blurry edges.

“These properties give the human eye twice the power to see an image composed of pixels. The eye is focused, refocused, relaxed, and focused. I’m forced to fix it. Thus, there is an extraordinary effort in the muscles of the eye, “he commented. Maria Beatrice.

“In addition, using electronic devices tends to reduce blinking and helps to smooth the surface of the eye, thus exacerbating the symptoms of dry eye,” experts add.

It is estimated that 70% to 90% of users of computers and other electronic devices have one or more symptoms of computer vision syndrome.

Inadequate ergonomics

Of course, there are other factors associated with computer vision syndrome. Some studies have pointed out that screen distance is related to the progression of the state.

“The closer the screen is, the more eyes need to work to achieve sharpness at a particular distance. This is called visual adjustment. In such cases, the screen is 50 ~ from the eyes. It is recommended to be 70 cm apart, “Dr. Maria Beatrice.

The ophthalmologist adds: “The tilt of the monitor is also important. When using a computer, a person cannot lower or raise his head too much. The line of sight must be in a straight line on the screen image.”

20-20 rules

Good ergonomics are essential for overall health, including visual health. Another tip is to rest your eyes every 20 minutes. This pause requires training of vision from a distance, but in these cases it is severely impaired. Finally, don’t forget to blink more in front of your computer.

Diagnosis of computer vision syndrome is basically clinical. “During regular consultation, it is possible to detect the condition. In some cases, a test called Tearcheck® can be performed to evaluate the surface of the eye and investigate dry eye. May cause further visual problems, “Dr. Maria Beatrice said.

In addition to ergonomic corrections when using a computer, treatment can be done with eye lubricants and habit changes. Finally, in the most severe cases, it is possible to use intense pulsed light to treat the symptoms of dry eye, with long-term results.

Finally, it’s always good to remember that eye drops shouldn’t be used without an ophthalmologist’s prescription! Misuse of these medicines is an important cause of the development of secondary glaucoma and other eye conditions.
