Health and learning go hand in hand. The school nurse has a multi-faceted role within the school setting; one that supports the physical, mental, emotional, and social health of our students and their families, while supporting the academic success of the student population.
Screen time can put considerable strain on the eyes. Signs of eye strain include eyes that feel dry, tired and/or blurred vision. In addition, head/neck or shoulder pain can develop with too much time sitting and using digital devices.
Below is some information from WebMD about eye strain and how to prevent it. Of course, limiting your child’s usual recreational tech time beyond what is required for distance learning may also be helpful.
Why Do Screens Cause Eye Strain?
Normally, we blink about 15-20 times a minute. That spreads tears evenly over your eyes, which keeps them from getting dry and irritated. Researchers have found that people blink less than half as often when they’re reading, watching, or playing on a screen. Also, the contrast of text against the background, the glare, and flickering from digital screens can be hard on your eyes.
Prevent Digital Eye Strain
No, you don’t have to cut out all screen time. But a few changes to how you use your devices can be easier on your eyes.
- Make sure your computer screen is about 25 inches, or an arm's length, away from your face. The center of the screen should be about 10-15 degrees below eye level.
- Cut glare by using a matte screen filter. You can find them for all types of computers, phones, and tablets.
- Follow the 20-20-20 rule: every 20 minutes, look at an object at least 20 feet away for at least 20 seconds.
- Take a longer break of about 15 minutes after every 2 hours you spend on your devices.
- Use artificial tears to refresh your eyes when they feel dry.
- Try putting a humidifier in the room where you most often use a computer or other device.
- Make sure the lighting in the room you’re in is bright enough. You don’t want your device to be brighter than the surroundings.
- If you wear contact lenses, give your eyes a break by wearing your glasses.
- Get regular eye exams. You might need to use a different pair of glasses when you’re working on a computer (this one may be difficult at this point in time).
Adjust Your Devices
You can also make sure your devices are set for eye health.
- Raise the contrast on your screen.
- Make text larger.
- Change the brightness of the screen. It shouldn’t be lighter or darker than your surroundings.
- Lower the color temperature of your screen. That means it will give off less blue light, which is linked to more eyestrain.
