Digital Eye Strain
What is Digital Eye Strain?
Digital eye strain, which is also referred to computer vision syndrome, is a collective term for eye and vision-related problems that result from prolonged use of digital screens such as computers and smartphones.
In today's context, it is quite unlikely that one will go without some form of digital screens in our daily lives. Even if we do not watch TV programmes or work in front of a computer, we rely on our smartphones for information and entertainment.
Symptoms & Causes
Digital eye strain can affect anyone of any age group. Some common symptoms include:
- eye strain
- blurred vision
- dry eyes
- neck and shoulder pain
These symptoms can be caused by one or a combination of the below factors:
- inadequate or poor lighting
- excessively bright digital screens
- improper seating posture
- uncorrected vision (long or shortsighted, astigmatism)
- improper viewing distance
Managing Digital Eye Strain
Take regular breaks from digital screens
Following the 20-20-20 rule will go a long way in managing the workload on our eyes for the day. The rule means that you should take a 20-second break after 20 minutes of near work by looking at something 20 feet away.
Spend more time outdoors
Parents should ensure that children spend a couple of hours outdoors everyday away from their tablets.
Minimize discomfort from blue light and glare
Lens tints and blue light filtering lenses can help to reduce the impact of the blue light emitted from digital screens. You can position the computer screens so that the reflection from the room lighting does not reflect off the screen. Adding a glare reduction filter may make it more comfortable to view your screen.
Set up a comfortable workspace
Ensure that the viewing distances and angles are suitable for you. This can be done by adjusting your monitor height or your seat height and posture.
We tend to blink lesser when our eyes are fixated on a screen, thus it is important to remind yourself to blink more frequently. This can help to minimize discomfort and blurry vision related to dry eyes.
Wear the correct prescription
Even small amounts of uncorrected vision problems like shortsightedness, longsightedness or astigmatism may cause eye strain. Wearing the necessary prescription may help to alleviate some of these eye strain. You may like to consider switching to anti-fatigue lenses.
