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
Increased time spent in front of a screen, whether that of a computer or a smartphone, is closely associated with dry eye and eye strain. It is extremely common, with about 50% of people who regularly use computers and smartphones experiencing some amount of dry eye.
Screens cause dry eye because when we are looking at them, we subconsciously reduce the frequency of blinking or we blink less fully. This leads to the eyes not being adequately lubricated, and thus dry eye.
Symptoms of eye strain include, apart from dry eyes, blurry vision, headaches, and in more severe cases, neck and shoulder pain.
Dry eye from screen use is most common among people who use screens for work, and are thus staring at them for extended periods of time.
Fortunately, there is no evidence that eye strain from screen use has long-term negative impacts on your eyesight, but the discomfort can be unpleasant and make it harder to get through the workday.
The best way to deal with computer eye strain is through prevention, rather than treatment, since the symptoms tend to subside if you take measures to prevent it.
Fortunately, there are simple measures 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 an 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.
Because computer and cell phone usage causes us to blink less fully, it is extremely beneficial to actively work on being better blinkers. According to a recent study by Dr. Portello,Christina A. Chu, O.D, M.S., and Mark Rosenfield, Ph.D. 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.

At Amplify with Dr Wernick I was seeking help for seemingly intractable, probably age-related dryness. I've seen other doctors about it, and that has been helpful, but what he explained to me about it and the careful way he answered all my questions gave me so much more of a clear understanding of what is going on (and is not) that I am more able to implement all his and others' recommendations than I was before. And he gave me additional resources for further follow-up. I am most grateful.
Wow! This is a great Eye Care medical facility. I was thoroughly examined by Dr. Pinkhasov for over 2 hours. She made sure to check my eyes for pretty much everything and patiently explained proper care for my eyes. They definitely know how to provide great care and treat their patients right. Now I know why they have such a great reputation and been around for so long.
Dr. Kavner is a gifted diagnostician and orthoptic therapist. He treated me several decades ago for a condition similar to dyslexia. I was having migraines five times per week. I worked with him for about a year and I experienced tremendous improvement (down to 3-4 per year) that has lasted.
Dr. Kavner recommended two types of eye therapy for my daughter. One of them using bio-feedback. In just three sessions she is seeing considerably better. She shouted this morning: Ooh my God! I could not see these letters with my glasses on, and now I can see them without my glasses. If you are willing and able to invest in improving your vision, this is a good place to go to!

I have always found Dr Kavner's work, expertise and wisdom of the highest caliber. As one of the fathers of OT, occupational othomology, his depth and breadth of knowledge about the eyes' health and wellbeing of the patient is exemplary. Cannot say enough good things about him.
