As an optometrist at Amplify EyeCare Chattanooga in Hixson, one of the most common questions Dr. Heather McBryar often encounters […]
Time spent looking at computer and phone screens is closely associated with dry eye.
As computer and mobile phone use has increased, so too has the prevalence of dry eye. Why is this, and what can be done to avoid it?
Take the Dry Eye Quiz to find out if you suffer from dry eyes
As we increasingly live in a world dominated by digital screens, the relationship between screen usage and dry eye syndrome has become more evident. Roughly 50% of individuals who consistently engage with computers or smartphones experience some level of dry eye. This is a common occurrence especially in the United States, where many individuals work long hours on digital devices.
The simple answer is that when we engage with screens, we unconsciously decrease our blinking frequency or don't blink fully. This interferes with our eyes' natural lubrication mechanism, leading to dry eye syndrome, a condition often dealt with by our eye care professional.
Symptoms of eye strain associated with screen use extend beyond dry eyes. They also include blurry vision, headaches, and in more severe cases, neck and shoulder pain. If you are in Hixson, and experiencing these symptoms, don't hesitate to contact us at (423) 710 3965 to schedule an appointment at our eye care clinic.
Dry eye from screen use is most prevalent among individuals who spend extended periods in front of screens for work. Fortunately, no evidence currently suggests that eye strain from screen use has long-term negative impacts on your eyesight. But the discomfort can be unpleasant and interfere with your daily productivity.
As an experienced optometrist, Dr. Heather McBryar would recommend prevention over treatment. The symptoms usually subside if preventive measures are put into practice.
Fortunately, there are simple measures that we have discussed below that you can take to effectively avoid this problem.
We aren’t meant to be staring all day at something right in front of us. The 20/20/20 rule is a good way to give our eyes important breaks over the course of the work day.
The way it works is simple. For every 20 minutes you spend looking at a screen, spend 20 seconds looking at something at least 20 feet away. This is just a minimum, however; looking away from the screen for more time is even better for your eyes.
These breaks where you use longer distance vision help keep the eyes from getting overly strained.
While it might not be obvious, you want to have less light in the room while working on a computer. It should not be dark, but also not too bright. You can achieve this by using less fluorescent lighting, closing curtains, and using lower voltage bulbs. The average office is usually too bright, and the overstimulation can increase the likelihood of eye strain and dry eye.
Glare on your screens can lead to eye strain since it prevents your eyes from adjusting as easily as they should to whatever you are trying to focus on.
To reduce glare, use an anti-glare matte screen when possible, as opposed to glass-covered LCDs. If you wear glasses as you work, make sure they have an anti-reflective coating.
Fortunately, computer screens today are better than the old CRT screens which had low refresh rates and created noticeable flickers. Most modern screens have refresh rates of 75Hz or higher. More is better. Screens with higher resolutions look more lifelike, and when you cannot see the pixels, your eyes won’t have to work as hard to make sense of what you’re seeing.
Getting regular eye exams will help you make sure that your eyes are healthy, and that any issues you might have do not become something major. Additionally, seeing our eye doctor gives you a chance to talk to them and seek advice regarding eye health.
Our computer screens are usually arm length away from our eyes. Our glasses however are not optimized for this viewing distance. Regular glasses are optimized for near and far vision. By using our eyes to look at a distance that is not optimized by our glasses, we can cause added eye focusing and eye movement demands on the visual system. Computer glasses are specially designed to optimize your vision for the right viewing distance to reduce strain when looking at a computer screen for extended periods of time.
One significant strategy that our optometrist recommends is practicing blinking. Due to the nature of computer and cell phone usage, we tend to blink less fully. Dr. Portello, Christina A. Chu, O.D, M.S., and Mark Rosenfield, Ph.D., found that computer usage resulted in 75% more incomplete blinks than reading from a printed document.
Exercise 1: Spend one minute actively blinking, doing fifty full blinks in that one minute period. Look in each direction (up, down, left, right, straight) and blink ten times in each direction (5×10). When doing this exercise, make sure that your blinks are complete by placing your finger sideways under your eye above your cheekbone, pointing towards your nose. When you blink fully you should feel a gentle brush of your upper eyelashes on your finger.
Exercise 2:
Close your eyes normally, pause for 2 seconds, then open them. Next, close the eyes normally once again, pause for 2 seconds, and then forcefully close them
Hold the lids together tightly for two seconds, then open both eyes. Repeat for 1 minute.
A firm squeeze is used to ensure that the muscles responsible for closing the eyelids are being used.
Exercise 3:
Put your fingers at the corners of your eyes and blink. During correct blinking, you should not feel any movement under your fingers.
When you feel anything, you are using your defense muscles on the side of your head. Practice blinking with the goal of using your blinking muscles that are above your eyelids.

Vision therapy is well worth the response, time and effort. Our Son had a hard time focusing and writing neatly. After vision therapy Seth could complete a task in half the time if previously took. His abilities to focus improved greatly and so did his handwriting.
Also, he was better at listening. As a parent, we wanted learning to be fun for our Son, and vision therapy made this possible.

Vision Therapy has given or son the tools he needs to be able to scan and read the written word more effectively and efficiently.
He love working with John and these working sessions give him the motivation to gladly work on his homework assignments.
It amazed us to see the difference in the tracking of his eyes and along a line of it's from the beginning to the end of the treatment.
Dr. McBryar , Kristen and John are all marvelous and we would recommend them to anyone I only wish that we would have found them sooner!
Prior to coming to the institute for vision development my son complained of daily headaches. Therapy has eliminated his headaches completely. I love knowing my son is able to learn pain-free for the rest of his life because of the work that has been done over just a few weeks in this office. He he absolutely loved coming that didn't even feel like going to a doctor or therapy. We are grateful for the relief he was able to find by coming here.
Thank you!

Reads non-stop and fast
Spelling abilities have been hugely improved
Seems much more confident
Thank You!!!
When we first came to the practice, my son did not have huge issues, but lots of small ones- trouble with reading, sports (hitting the baseball consistently), coordination, etc- that were not easily detectable,but when put together presented issues. The staff here were all very professional and loving towards him. While I was concerned in the reading, my son was concerned with the athletic side. Seeing improvement night off the bat gave him confidence that i have nor seen in him and made him want to not only Come to therapy, but also made him want to work hard. He has surpassed his grade level and above in reading and hit his first home run this year! Thank you!!!
