Digital Eye Strain and COVID-19
By Dr. Tina Goodhew Updated: April 28, 2020
No matter what your age, it seems that everyone has been spending more time on digital devices during this pandemic. Although digital device use cannot cause permanent damage to your eyes it can cause symptoms such as eye strain, headaches, dryness, and even interfere with your sleep.
Here are some tips to help you alleviate these symptoms.
Give your eyes a break
- Set a timer on your phone. Every 20 minutes, look 20 feet away for 20 seconds, we call this the 20-20-20 rule.
- For every 2 hours you spend on your devices, take a longer break of about 15 minutes.
Adjust your screen
- Make sure your computer screen is about 50-70 cms, or arm’s length away for your face.
- Try to position the center of your screen slightly below eye level to decrease discomfort from poor posture.
- Adjust the brightness of your screen to match the level of ambient light around you.
- Position your screen away from glare sources such as windows and lights.
Moisturize your eyes!
- Try to remember to blink! Studies show we blink only half as much as we normally do when looking at screens. This causes dryness, burning, and eye fatigue.
- Use artificial tears to refresh your eyes when they feel dry.
- You can also use a humidifier to add moisture to the air.
- For more severe symptoms consider using a warm compress. Place a clean towel in warm water and place over the eyes for 5 minutes.
- Contact lens wear can contribute to dryness, consider removing them, and wearing your glasses.
- Digital devices emit high energy blue light which studies have linked to poor sleep quality. Try to avoid device use 1 hour before bedtime.
- Consider turning on “night mode” on your devices in the evening to decrease the blue light exposure.
- Consider glasses that have a blue-blocking filter in them. Blue light emitted from your devices, while not damaging to the eye, can cause significant eye strain, headaches, and fatigue.
