11 Mar How Digital Screens Affect Our Vision
As we transition into a world that relies on smart devices to complete daily tasks, we need to consider the extended screen time we spend on these devices and how badly they can affect our vision.
A survey before covid-19 pandemic shows that an average person spends nearly seven hours per day looking at a screen. I’m very sure the number of hours would have increased by now considering the effect of lockdowns and quarantines on our daily lives.
Although, there’s not much evidence that screen use causes permanent damage to our eyes. However, when we stare at one for long stretches of time every day, we can develop computer vision syndrome, also called digital eyestrain.
Headaches, blurred vision, dry eyes and neck and shoulder pain are the most common symptoms of digital eye strain.
The easiest solution to eye strain would have been to reduce screen time but for some of us whose job solely depends on computers, I’m sorry to say its far from possible! However, there are simple steps we can take to make our screen time more comfortable and less damaging for our eyes.
- Taking intermittent break while starring at your screen. Use the 20-20-20 rule: every 20 minutes, look at an object at least 20 feet away for at least 20 seconds.
2. Reposition screen to about 25inch away from the eyes. Position your PC in such a way that you’re looking slightly downward at the screen
3. Adjust device lighting to avoid glare or use an anti-glare screen.
4. Regular blinking
5. If you wear contact lenses, give your eyes a break sometimes by wearing your glasses.
Above all, get a regular eye examination. You might need to use a different pair of glasses when you’re working on a computer.
