Computer vision syndrome (CVS) is a prevalent condition that often affects individuals who spend extended periods in front of computer screens, including those who use smartphones, TVs, and tablets. The continuous focus on screens strains the eyes and can lead to the development of CVS.
CVS encompasses a range of visual, neurological, and motor symptoms, impacting approximately 70 to 90 percent of individuals who spend significant time in front of screens, often without their knowledge.
Computer vision syndrome: the symptoms
Symptoms associated with CVS are diverse and include:
- Burning eyes
- Musculoskeletal discomfort due to prolonged static positions
These symptoms are typically transient and dissipate upon moving away from the screen.
It is important to note that prolonged screen use reduces the frequency of natural eye blinking from the average rate of 17 to 20 times per minute to approximately 12 to 15 times per minute, adding additional strain to the eyes.
The Impact of Electronic Devices on Vision
When it comes to computer vision syndrome, the eyes are commonly affected by symptoms such as:
- Double or blurred vision
- Burning sensation
- Overall dryness
These symptoms typically manifest after several hours of continuous device use rather than appearing immediately. They can significantly impact an individual’s performance, leading to decreased concentration and feelings of discomfort and anxiety.
While specific individuals may be more predisposed to experiencing these symptoms, factors such as low-resolution monitors or poorly defined characters can contribute to their occurrence.
Furthermore, the decreased frequency of eyelid closure exacerbates the sensation of dryness and fatigue, potentially leading to increased redness in some individuals.
Computer vision syndrome: What to do
While computer vision syndrome can be bothersome, it does not cause long-term damage. However, it can increase the risk of developing other conditions, such as dry eye syndrome.
Here are some remedies that can help alleviate eye strain:
- Take regular breaks and focus on a spot 10 meters away for at least 20 seconds every 20 minutes. Stand up, stretch, and relax your neck during these breaks.
- Use a high-definition screen with sharper fonts and higher contrast to reduce visual fatigue.
- Position the monitor at 50 to 70 centimeters from your eyes, ensuring the top edge is at eye level, and your head is slightly tilted downward.
- Adjust the screen brightness to be slightly higher than the he surrounding environment. Create a work environment that is not overly bright and free from reflections that strain the eyes.
- Consider using software that can filter and reduce the blue light emitted by monitors, making the light more yellow.
- Maintain good posture while using a smartphone by keeping your shoulders and head back. Bring the screen closer to your face instead of leaning forward, which will improve your posture and minimize strain on your arms.
By implementing these measures, you can help reduce the discomfort associated with computer vision syndrome and promote healthier eye habits.
