Does screen time really cause dry eyes?
What's the story
In today's digital age, many people are concerned about the impact of screen time on dry eyes. With prolonged exposure to screens, the belief that dry eyes are inevitable has become common. However, understanding the facts behind this myth can help in managing eye health better. This article aims at debunking common misconceptions about dry eyes and screen time, giving you insights into how screens affect our eyes.
#1
Screen time doesn't cause dry eyes
Many believe that staring at screens all day causes dry eyes. However, research indicates that while screen time may contribute to eye strain, it doesn't directly cause dryness. The real culprit is reduced blinking when focusing on screens for long periods. This leads to less moisture on the eye's surface but isn't a direct result of screen use itself.
#2
Blinking is key to eye moisture
Blinking is essential for keeping our eyes moist and healthy. When we look at screens, our blinking rate decreases significantly—by as much as 66%, according to studies. This reduced blinking leads to tear film instability and potential dryness over time. Being mindful of regular blinking during screen use can help mitigate these effects.
#3
Not all screens are equal
Not all screens have the same effect on eye health. Older CRT monitors emit more blue light and flicker more than modern LCD or LED screens, which can add to eye strain and discomfort. Choosing modern display technologies with blue light filters and adjustable brightness settings can reduce any negative impact on eye moisture.
#4
Regular breaks are essential
Taking regular breaks from screens is essential for keeping your eyes healthy. The 20-20-20 rule is a good practice: every 20 minutes, look at something 20 feet away for 20 seconds. This simple habit encourages blinking and gives your eyes a much-needed break from constant focus, reducing strain and keeping them moist.
#5
Hydration matters for eye health
Staying hydrated is also key to keeping your eyes healthy. Drinking enough water ensures that your body produces enough tears to keep your eyes moist naturally. While reducing screen time can help, staying hydrated is a simple way to support overall eye health without having to change daily habits drastically.
