Computer Vision Syndrome
Digital eye strain, also known as computer vision syndrome, is a group of eye and vision-related problems that can result from prolonged use of digital screens. Symptoms of digital eye strain may include:
- Dry, red, or irritated eyes
- Headache
- Neck, back, and shoulder pain
- Blurred vision
- Difficulty focusing
Originally referred to as “computer vision syndrome,” digital eye strain has been recognized as a legitimate health issue for over two decades. As the use of various electronic devices has become more widespread, the term “digital eye strain” has been adopted to encompass the effects of all types of screens. This condition has become a clear public health issue that can be difficult to identify and treat. As doctors, we often recommend that patients reduce their screen time to alleviate the symptoms of digital eye strain, but this can be a challenging solution to implement.
It can be challenging for many people to reduce their exposure to digital screens, as computers and other electronic devices are often essential tools in the workplace and are used for a wide range of activities, such as watching movies, playing games, reading, shopping, and getting directions. It is not uncommon for people to spend 8 or more hours per day using these devices, and they have become an integral part of daily life for all age groups. It is important to stress the importance of taking breaks from screen use to give the eyes a rest when discussing this issue with patients.
How to reduce the risk of digital eye strain
- Take frequent breaks: Follow the 20-20-20 rule – every 20 minutes, take a 20-second break and look at something 20 feet away.
- Adjust your screen: Make sure your screen is at a comfortable distance and angle, and consider using an anti-glare screen to reduce reflections.
- Blink frequently: Blinking helps to keep your eyes lubricated, so try to blink every few seconds to keep your eyes moist.
- Use good lighting: Avoid glare and bright lights that may strain your eyes.
- Use the right corrective lenses: If you wear glasses or contacts, make sure you have the correct prescription and consider getting glasses specifically for computer use.
What causes digital eye strain?
There are several factors that can contribute to the development of digital eye strain:
- Prolonged use of electronic screens: The longer you use a digital screen, the greater the risk of developing digital eye strain.
- Poor screen position: If your screen is not at the correct distance or angle, it can strain your eyes.
- Glare: Glare from a screen or surrounding lighting can cause eye strain.
- Incorrect lighting: Poor lighting, either too bright or too dim, can strain your eyes.
- Dry eyes: Dry eyes can be caused by a variety of factors, including prolonged screen use, and can contribute to digital eye strain.
- Poor vision: If you have uncorrected vision problems or are wearing the wrong corrective lenses, it can strain your eyes to use digital screens.
- Blue light: The blue light emitted by electronic screens may contribute to the development of digital eye strain.
Treating computer vision syndrome
The American Medical Association (AMA) recommends that a comprehensive eye examination be used to diagnose digital eye strain. This should include a consideration of the visual requirements for the distance at which the patient uses their computer or digital device, as well as a review of the patient’s medical history to rule out any general health conditions or medications that may be contributing to their symptoms. Visual acuity measurements, such as refraction to assess the need for corrective lenses, can also be useful in diagnosing digital eye strain. Other tests, such as those that evaluate how the eyes focus, move, and work together, can also be helpful in identifying the condition.
Treatment options for digital eye strain may include the use of corrective lenses and vision therapy, as well as changes to the workspace environment to improve lighting and the position of the computer monitor. Using an anti-glare screen filter and taking breaks to rest the eyes can also be helpful in reducing the risk of digital eye strain. To learn more about this condition and how to prevent it, please schedule a consultation with a healthcare professional.
