Kids, like adults, are spending more time online. At some point during the pandemic, many children attended school via video conferencing apps and completed assignments online. The trend toward more screen time is likely to continue. We already know that prolonged screen time can cause digital eye strain as well as dry eye symptoms in children and adults. There is also concern that extended exposure to blue light may impact the development of retinal cells over time.

Dry Eyes

Spending a long time in front of screens impacts 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. Remind your child to blink frequently to prevent their eyes from drying out!

Blue Light Exposure

Screens emit blue light. Recent studies have shown that overexposure to blue light can damage the retinal cells at the back of your eyes, potentially increasing the risk of age-related macular degeneration. Excess blue light has also been shown to disrupt sleep patterns by tricking your internal clock into thinking it is the middle of the day.

Digital Eye Strain

Nearly 60% of people who routinely use computers or digital devices experience symptoms of digital eye strain, also called computer vision syndrome. Symptoms include eye fatigue, discomfort, dry eye, headaches, blurred vision, neck and shoulder pain, and red eyes.

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
