How are screens impacting our vision?

Working from home has its benefits, like eliminating the need for a commute and allowing for more freedom and downtime. However, studies have shown going remote has also increased total numbers of hours worked.

In addition to more adults working from home, many children have transitioned to an online school model following the pandemic. These life changes have led many people to wonder about the effects of prolonged blue-light exposure, as well as higher levels of screen time, especially how it may impact young Americans who’ve been exposed to screens much earlier than older generations.

To better outline the effects of increased screen time on the body, we surveyed 1,000 full-time employees, of which over 70% were parents. Read on to learn more about the relationship between screen time and health among American workers today. 

Key takeaways

  • Remote employees spend nearly 13 hours per day, on average, staring at screens.

  • 43% of remote workers have left work early due to vision problems.

  • 83% of those who used blue-light lenses reported good to excellent sleep compared to just 63% of non-blue-light lens users.

Is working from home bad for us?

Many more employers are allowing people to work from home as they’ve found it’s a viable alternative to working in the office. Studies have shown productivity increases when employees are allowed to work from their preferred home space.

With improved technology and support for work from home initiatives on the rise, workers should consider how these changes affect the amount of time they spend staring at screens. 


When compared to on-site workers, those working from home reported spending more time overall looking at screens, scrolling handheld devices and watching TV. We observed remote workers spent over two hours more on screens each day than on-site workers.

Trends also suggest remote workers take more time off or leave work earlier due to eye strain or headaches. Because of increased productivity, 68% of remote workers said they noticed new eye or vision symptoms since working from home, and 26% of all employees felt unable to take breaks due to work responsibilities or pressures.

Eighty-eight percent of survey participants reported visiting the eye doctor in the past 2 years, and 45% of these workers said their eyesight had worsened to the point they needed a new eyeglass prescription. While it might just be a coincidence, working from home and spending more time in front of screens may have contributed to poorer eye health.


According to our survey results, working from home sometimes appears to be worse for workers’ health than working in an office. But remote work doesn’t have to negatively affect your life if it’s the better option for you and your family. A few simple changes to how you work at home can lead to great benefits. Consider these tips:

  • Take frequent breaks when spending long hours working at a computer or looking at screens. It may seem counterproductive, but when you’re looking at a screen 24 inches away or closer for long periods, screen breaks are necessary and may help reduce eye fatigue.

  • Practice the 20-20-20 rule, in which 20-second breaks are taken to observe an object at least 20 feet away for every 20 minutes of staring at a screen. It helps ease eye strain and can also be an exercise in mindfulness to remain involved with your work.

  • Limit screen time by performing tasks that don’t involve screens.

  • Use blue-light blocking glasses.

  • Turn on night mode/dark mode on your devices. Don’t use the devices immediately before bed.

Do blue-light blocking glasses make a difference?

There are many variables involved when analyzing the effects of blue-light glasses, but scientific studies suggest there is more potential for help than harm when considering whether to wear them. When our faces are almost constantly lit by device screens, it puts a lot of stress on our eyes. Wearing blue-light blocking glasses can help substantially alleviate this problem.

Depending on the lenses, blue-light glasses can block anywhere from 10% to nearly 100% of blue-violet waves. Using blue-light filtering features on smart devices can also help to block these waves. More than 6 in 10 survey respondents reported using night mode/dark mode on their phones in addition to or in place of blue-light blocking glasses.

A majority of remote workers (73%) used some form of blue-light blocking glasses/lenses, and of this group, 67% attributed having less eye strain to their use of blue-light glasses. Protective lens users also reported experiencing a better quality of sleep compared to those who didn’t wear any form of blue-blocking lenses. Wearing these glasses had such positive effects on people’s health and wellness that 85% of wearers said blue-light glasses are a must for anyone who works from home, and 92% had recommended these glasses to someone they know.

Keep in mind, blue-light filtering glasses aren’t recommended as a cure-all for every eye ailment but as a tool to help relieve the harmful effects of blue light. Blue light is nearly impossible to avoid as a shorter wavelength of visible light, but it isn’t all bad either. Some blue light exposure can be good for you under certain circumstances.

The eyesight of future generations

Because of the prevalence of technology in the modern household, kids have more access to screens than their parents’ generations. Being aware of this fact means parents should consider how screens affect kids’ eyes and develop healthy eye habits with them.


If adults who regularly observe a screen for long periods report having issues with their vision, it’s worth considering the impact of blue light on younger eyes. Among those surveyed, 71% were parents, and they reported their children are usually on screens for an average of three hours per day. The number of hours kids spend on screens may actually be much higher than they estimated, with some teens spending up to 9 hours per day.

Many parents seem aware that too much blue light isn’t good for their kids, as more than 6 in 10 parents had bought blue-light blocking glasses for their kids. Sixty-seven percent of parents had also reduced their children’s screen time as an added precaution.

It’s possible for people of all ages to suffer from digital eye strain. An adult or child who has been overexposed to blue light from screens may have one or more of the following symptoms:

  • Vision changes

  • Dry eyes

  • Eye fatigue

  • Physical fatigue

  • Poor posture

  • Headaches

Even if a child doesn't have an eyeglass prescription, wearing a pair of blue-light glasses could be beneficial during a child’s development. Limiting screen time also helps to reduce digital eye strain and its negative effects. Keep in mind, common childhood vision problems may still be present regardless of preventative eye care routines, so talk to your child’s doctor if symptoms don’t improve with care or if you notice new symptoms.

Are you protecting your eyes?

If you’re anything like our survey participants, you’re probably considering buying blue-light blocking glasses for yourself and your family if you haven’t already done so. Using these lenses could lead to a better quality of life, or they may not make a noticeable difference at all. It all depends on each person’s daily screen time exposure.

Prioritizing your vision and the eye health of your kids as soon as possible can mitigate worse symptoms in the future. Schedule frequent eye exams with an eye care professional to learn more about your unique eye needs and to ask about solutions to harmful blue light exposure.


All About Vision surveyed 1,000 Americans about their screen time: 33.53% worked a hybrid schedule; 33.23% worked on-site, and 33.23% worked remotely. Of those we questioned, 71% were parents, while 29% were not. The margin of error was 3%, with a 95% confidence level. For short, open-ended questions, outliers were removed. Survey data has certain limitations related to self-reporting. These limitations include telescoping, exaggeration and selective memory.

Correlation, not causation

Headaches and vision problems at work may not be due to excessive blue light. The explanation could be excessive stress or using near vision too much, among other things.
