The Covid-19 Lifestyle, Blue Light and Your Eyes

Whether it’s working from home, online schooling, or shopping online, the pandemic has changed the way we live; we are spending much more time online, staring at screens. However, that constant exposure to blue light can adversely affect eye health. Tom Chang MD is a world-renowned eye surgeon, speaker and educator. He has lectured worldwide and is listed in the Who’s who as one of the Best Doctors of America.


The ophthalmologist explains that blue light is a short wavelength, high-energy source of light. However, while the sun is the natural source of blue light, screen time also exposes us to a source of unnatural blue light, adds specialized ophthalmologist Tom Chang MD. Natural blue light wakes us up and keeps us alert during the day. Unfortunately, our modern online lifestyle creates too much blue light exposure which can trigger eye strain, migraines, and insomnia. It can even increase the risk for chronic eye maladies. Fortunately, there are ways to easily reduce the harmful effects of blue light.


First of all, limit your screen time, especially before bedtime. Once the sun begins to set, unplug yourself from your devices. Also, many mobile devices have a nighttime setting that reduces the level of blue light. Second, get a pair of blue light glasses. You can find these as reading glasses with or without magnification. Blue light glasses have yellow-tinted lenses, which counteract the blue light. Finally, Tom Chang MD recommends, give your eyes a break during the day. Every twenty minutes or so, take your eyes off of your screen and look at something in the distance for a minute. The post-covid lifestyle has many of us working and going to school online, But that does not mean we cannot take steps to care for our eyes.
