What Is the Long-Term Impact of Virtual Learning on Children's Eyes?
Kids, like adults, are spending more time online. At some point during the COVID-19 pandemic, many children attended school via Zoom and completed assignments online. The trend toward more screen time is likely to continue even after everyone returns to the classroom.
We already know that prolonged screen time can cause digital eye strain as well as dry eye symptoms, among other problems in children and adults. There is some indication that extended exposure to blue light may impact the development of retinal cells.
Dry Eyes
Spending a long time in front of screens can impact how quickly our tears evaporate, because we blink around 66% less when using a computer compared to other daily activities. When tears evaporate too quickly and aren't replenished with blinking, our eyes start to feel dry and gritty. Remember to blink every few seconds to prevent your eyes from drying out!
Blue Light Exposure
Screens such as those on computers, phones and tablets emit blue light. Recent studies have shown that overexposure to blue light can damage the retinal cells at the back of your eyes. This may increase the risk of vision issues such as age-related macular degeneration. Excess blue light has also been shown to disrupt circadian rhythms, leading to difficulty falling asleep and daytime fatigue.
Digital Eye Strain
Nearly 60% of people who routinely use computers or digital devices experience symptoms of digital eye strain. Symptoms include eye fatigue and discomfort, dry eye, headaches, blurred vision, neck and shoulder pain, eye twitching, and red eyes.
Taking frequent breaks from your screen can help reduce eye strain. It is recommended to take at least one 10-minute break every hour. Also use the 20-20-20 rule: look away from your computer at least every 20 minutes and gaze at a distant object at least 20 feet away for at least 20 seconds.
How to Make Virtual Learning Safer For Your Child
- Reduce overall screen time
- Encourage frequent breaks
- Use accessories that filter blue light (such as blue light glasses)
- Schedule regular eye exams
If you are concerned about the effect of virtual learning and screen time on your child's eyes, or if you're due for a checkup, schedule an eye doctor's appointment at Eyecare Professionals of Gahanna in Gahanna.
Q&A
What are blue light glasses? Blue light glasses, also known as computer glasses, effectively block the transmission of blue light emitted from devices and computer screens. They often include a coating to reduce glare and further reduce eye strain. These glasses can be purchased with or without a prescription.
What's the 20-20-20 rule? If you find yourself gazing at screens all day, make sure you schedule frequent breaks and follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. And while you're at it, use this time to get up, walk around, and stretch.
