Technology and Vision

Image of a man thinking and looking to the side.

The primary sufferers of technology-related eyestrain used to be adults whose work involved computers. Now, however, people of all ages use computers, smartphones, tablets and gaming devices, which can take their toll on the eyes. As people’s reliance on technology grows, so does the incidence of eyestrain. Keep reading to learn more about digital eyestrain and how you can protect your eyes in the digital age.

How Much Screen Time Is Too Much?

After two hours of screen time, the eyes typically begin to get tired and suffer from digital eyestrain. Additional contributing factors to developing eyestrain include small print, devices held at non-ergonomic angles too far from eyes and the blue light emitted from digital screens. People who wear glasses or contacts are even likelier to strain their eyes, as their prescriptions might not be ideal for mid-range viewing of electronics.

Screens and Blinking

When going about their day, the average person blinks approximately 18 times per minute. However, staring at a screen slows the blink rate. This can lead to itchy, dry and burning eyes. Office workers with computer-related jobs may even undergo physiological changes to their eyes that are similar to those experienced by people who suffer from dry eye disorder.

Age-Related Trends

People of different ages tend to use technology differently. The Vision Council, which represents optical industry suppliers and manufacturers, analyzed these differences in its 2015 report on digital eyestrain. The council determined that Millennials (individuals born between 1981 and 1996) and members of Generation X (individuals born between 1965 and 1980) are the most likely to strain their eyes due to screen overuse. Sixty percent of Millennials and nearly one-third of Gen Xers spent nine or more hours per day looking at a screen. Only 26 percent of Baby Boomers (individuals born between 1946 and1964) are as glued to digital technology as the aforementioned generations. About 63 percent of Gen Xers and 68 percent of Millennials reported symptoms of digital eyestrain.

Protect Your Eyes

Despite the rise of digital eyestrain, most people are not about to give up their smartphones and tablets. So how do you protect yourself? Here are a few ways:

  • Tweak your lighting. Turn down your ambient lighting when looking at screens, and avoid fluorescent tube lighting. Windows should be to the side of your computer, rather than directly in front or behind it.
  • Pick the right display. Liquid crystal displays (LCDs) with flat panels are better than cathode ray tube (CRT) monitors. If you are still using a flickering CRT display, it is time to upgrade. Go for a larger screen with high resolution.
  • Adjust your computer’s display settings. Brightness should be about the same as that of your surrounding area. Use the “view” menu to zoom in and make text bigger without changing the font size. Reduce the color temperature to reduce blue light. Microsoft Windows users will find display settings in the control panel. Apple users should look in systems preferences.
  • Take breaks. Blink. Look off into the distance. Better yet, get up and walk around.
  • Get regular eye exams. Your eye doctor is your ally in avoiding digital eyestrain. Discuss your computer use, how far you sit from the screen and what other devices, such as tablets and smartphones, you typically use.

  • "Wonderful experience! From the moment I walked in, I felt at ease and comfortable. The staff is welcoming, friendly, and personable. I would highly recommend Dr. Huser and her team."
    Kelly R.
  • "I'm always greeted well as soon as I walk in. The wait time is nonexistent, besides there's coffee or water to enjoy before going in (if there is a wait). Plenty of time to check out new frames & of course the glass bowl of Hershey kisses awaits you.Dr.Huser is honest and really cares. I don't ever feel like just another number. The staff all work as a team and you can tell they all love their job. Makes me want to work there."

  • "Met Dr. Tekell for my annual appointment. She is very personable and professional. So easy to talk to. It was a very good appointment. So glad to see that although Dr. Jackman is not physically here anymore, his staff is continuing his great practice! Sure do miss him!"
    Ruby A.
  • "I have always had a wonderful experience at this location with all of their personnel and with the doctors. I have complete confidence in the accuracy of the exam. The excellent help of the staff ensures that the fit of the frames and of the way the lens sit in the frames is perfect. My previous frames were made with expert precision and durability, and have lasted for the past 4 years with no problems. They were built to last and that is hard to find in this day and age. If I could give a perfect 10 rating, I would."

  • "My 1st visit was in 2016 with Dr. Huser. She was terrific: engaged, knowledgeable, excellent communication skills. I later recommended her to my husband, and was even more pleased with the outcome. She diagnosed the source of his chronic eye irritation — relieving us of the fear that it might be a permanent result of surgery he’d had elsewhere — and offered some simple interventions which have actually worked. Saw Dr. Tekell recently when Dr. Huser was out of the office and was similarly impressed. This is a quality practice and they’ve assembled a great team — excellent optometrists, supported by friendly and helpful staff, and opticians who know their stuff, too."

    Jason M.
  • "Absolutely had the best experience! Jan is a star in my eyes filled with kindness and professionalism. The entire crew was super nice and accommodating to my 86 year old mom and me. I will never go anywhere else to get an eye test, or to get glasses. Thank you for making our day and for going above and beyond my wildest expectations."
