You've probably heard about this diagnosis. It's now commonly referred to as "computer vision syndrome" by doctors. Long-term use of not only computers, but also e-books, mobile phones, and tablets, is, of course, one of the causes.

Fortunately, the theory that this can lead to irreversible changes in the eyes or vision has been refuted. 

Doctors give a simple explanation for the occurrence of dry eye syndrome: 

Evolutionarily, the human eye was not made to work long hours in front of a computer screen. When visual demands are higher than visual capabilities, the risk of getting dry eye syndrome goes up.

Naturally, the longer the use of digital screens, the higher the degree of anxiety.

Of course, you don’t have to give up on online slots for real money in South Africa, but you should prioritize your health. So, if you're experiencing any of these signs, here's what you should do.

Dry eye syndrome is manifested by the following signs:

  • dry eyes
  • Redness
  • A feeling of "sand in the eye"
  • I have a feeling of something strange in my eye.
  • burning
  • paradoxical lacrimation
  • photophobia
  • distortion of vision.

These clinical signs are temporary and may go away after you stop using computers or digital screens, but in some cases, they may be permanent:

The clinical signs are:

  • headaches
  • I have neck, back, and shoulder pain.
  • Blurred vision
  • dichotomy
  • Redness
  • dryness in the eyes.

The risk factors and causes are:

  • 2 or more hours of continuous work on the computer.
  • The presence of glare and reflections from computers makes it difficult for the eyes to work.
  • incorrect distance and angle from the computer.
  • incorrect posture
  • insufficiently fixed visual issues.
  • When visual demands exceed a person's visual capabilities,
  • poor lighting.

Ophthalmologists say that the main reason for dry eyes in people with computer vision syndrome is that they blink less.

How to prevent

First of all, the specialists call for maintaining the correct posture. The screen should be at a distance of 50 cm from the eye, tilted down by 15-20 degrees. Align the chair with the body structure, and put your feet on the floor, and your wrists on the keyboard. Place the reference materials next to the keyboard or under the monitor.

Adjust the brightness and contrast of the controller screen. If the screen is brighter than the lighting in the room, your eyes need to work harder to see clearly.

Blink often. We usually blink 15 times per minute, but studies have shown that when using a computer or other digital screen, we blink only 5-7 times, which leads to dryness of the eye surface. Try to make a conscious effort to blink often.

Follow the 20-20-20 rule: look at an image that is 20 miles away for at least 20 seconds every 20 minutes.

Use PC glasses. Its use can reduce eye strain. PC glasses are not the same as glasses that isolate blue light. 

Moisturize your eyes. Use eye drops and place humidifiers next to your desk.

And, of course, consult an ophthalmologist when you notice:

  • visual impairment
  • photophobia
  • lacrimation
  • burning
  • dichotomy
  • once a year, regardless of whether you have a complaint or not.

Of course, we cannot abandon or drastically reduce the use of computers, mobile phones, or tablets. However, guided by these tips, dry eye syndrome can be avoided.
