Digital eye strain, also known as computer vision syndrome, is a group of eye and vision-related issues resulting from extended computer, tablet, e-reader, and smartphone use. Many individuals experience eye strain and other visual symptoms when viewing digital screens for extended periods. The level of discomfort seems to increase with the amount of digital screen use.
The main cause of digital eye strain is the extended and unbroken use of devices that require intense focus and concentration. This is especially true in less-than-ideal conditions, such as poor lighting, sitting too close to the screen, not taking enough breaks, and improper viewing angles.
Screens also expose viewers to glare and reflection, which can exacerbate symptoms. Moreover, the blue light emitted from digital screens can cause discomfort and may interfere with your sleep cycle. Our eyes are not designed for prolonged direct exposure to blue light.
Additionally, certain pre-existing vision problems, such as astigmatism and presbyopia, can contribute to the development of digital eye strain. Individuals wearing glasses or contacts with incorrect or outdated prescriptions may experience more severe symptoms.
Digital eye strain symptoms may vary from person to person. Still, they usually include blurry vision, dry and irritated eyes, frequent headaches, neck and shoulder pain, and difficulty concentrating. Some people may also experience increased sensitivity to light or the sensation that they cannot keep their eyes open.
One of the most troubling effects of digital eye strain is its impact on productivity. When your eyes are strained, you'll likely have trouble staying focused, which can significantly affect your work. Digital eye strain can also affect your mental health. Regular headaches and the constant discomfort can lead to stress and anxiety.
There are several practical steps you can take to minimize screen-related discomfort. Firstly, ensure that you take regular breaks from your screen. Follow the 20-20-20 rule: every 20 minutes, look away from your screen and focus on something 20 feet away for 20 seconds. This helps rest your eyes and reduce strain.
Secondly, adjust your screen's brightness and contrast to a comfortable level. Make sure your screen is not too bright or too dark, as both can cause strain. Also, consider the position of your screen. It should ideally be slightly below eye level and about an arm's length away.
Lastly, don’t forget to blink. When we’re focused on a screen, we tend to blink less often, which can lead to dry and irritated eyes. Make a conscious effort to blink more frequently to keep your eyes lubricated.
Blue light lenses can also help in managing digital eye strain. These glasses have specially-crafted lenses that are purported to block or filter out the blue light given off from digital screens. As a result, they can reduce exposure to blue light and help alleviate symptoms of digital eye strain.
If you're experiencing persistent symptoms of digital eye strain, it's time to see an optometrist. An optometrist can perform a comprehensive eye exam to determine if your symptoms are caused by digital eye strain or if they're a sign of something more serious.
Managing digital eye strain is crucial in this digital age. By understanding what causes digital eye strain and how it affects us, we can take proactive steps to alleviate discomfort. Regular eye exams, a well-set-up workspace, and good screen habits can go a long way in managing digital eye strain.
