What Causes Digital Eye Strain?
Luckily, digital eye strain doesn’t lead to permanent eye damage, but it can be uncomfortable. The primary cause of eye strain is focusing for too long on one spot, which can also happen when reading, driving, or performing close-up work like sewing.
We also tend not to blink when focusing on one spot, which can dry our eyes out and intensify symptoms. Additionally, hot or cold air blowing from a vent, wearing incorrect prescription glasses, or working in a room with improper lighting (either too bright or too dim) can worsen symptoms. There are some things you can do to counter the symptoms, though.
Stretch Your Eye Muscles
If your legs or arms are sore, you might get up to walk or stretch them out. The same can be done with your eyes. All you need to remember is the number 20: every 20 minutes, look at something about 20 feet away for at least 20 seconds. This is called the 20-20-20 rule.
