Does Screen Time Actually Hurt Your Eyes? We Asked an Expert


For those of us whose jobs require us to look at a computer all day, our lives can feel like a never-ending series of screens. From considering a computer at the job to checking our phones during our leisure time, the potential effects on your own eyes could be scary. We wondered if we were doing damage to our eyes with this daily routines, and when we were, what we’re able to do to lessen the strain on our eye by the end of your day. We asked ophthalmologist Ashley Brissette, MD MSc, Assistant Professor of Ophthalmology at Weill Cornell Medicine, NYC that. She told us might find out about becomecome worried about regarding screens and our eyes, what myths are lurking across the Internet, and what we are able to do to avoid any injury to them.

If you work a 9-5 where you look at a computer all day, how does it affect your eyes?

Computer screens and digital devices can affect the eyes several different ways. First, when we use displays and read or scroll through media, we blink less that may cause the eyes to dry out. In fact, it’s known that we blink half just as much as our normal blink rate (approximately 15x one minute) whenever we use computers and digital devices.

Some symptoms people experience when their eyes are dry include blurry vision, burning, irritation, heavy or tired eyes, eye strain, and even tearing up (reflex response to the dryness!)

The above symptoms can lead to eye strain, headaches, and even stress. The level of discomfort also increases with prolonged computer use and could worsen over time. The above signs and symptoms in association with computer use has been known as “pc vision syndrome”


Have you seen significant damage done to your patients’ eyes from excessive screen use?

It is unlikley that excessive screen use will cause permanent damage to your eyes. However, eye strain and dry eye symptoms can worsen over time, especially with prolonged computer use and when not treated early on.

Is there anything you can do to lessen the damage screens are causing to your eyes if you do need to look at a screen all day?


If you do have to look at a screen for long hours, a good rule of thumb is the “20-20-20” guideline: every 20 minutes, shift your eyes to check out an object at least 20 feet away for at minimum 20 seconds. Taking regular breaks is essential for resting the eye, blinking, and limiting eye strain.


If you experience a lot of glare, you can test a matte screen filter over the screen


Consider having a humidifier in the office or near your computer if the encompassing air is dry


Use artificial tears – these are moisturizing drops for the eyes, they are sold over the counter at the pharmacy and there are lots of brands available, and it’s a personal preference to which to utilize, some people like a drop ththet’s more thick, others like thethinnerin. Just avoid any drops that say “obtain the red out” as they can make your eyes more red-colored once you stop using them. You may use them as needed if the eyes feel tired/heavy/dry/irritated or if you’re at the computer for long hours. If you are using them more than 4x a day, I recommend preservative-free versions of the drops.


Blink exercises (yes, remind yourself to blink!)


What influences your eyes more, looking at a computer screen or phone screen?


Both can effect the eyes, as when we stare at a screen we blink less, which can cause the eyes to become dry. Think about screen time as a total of all digitial devices – computers, tablets, smart phones, etc. We often move from computer to cellular phone to Netflix on our tablets during the day, and these can all impact the eyes.


How long does it take for looking at a screen all day to affect your eyes?

The effect of screen time is different for everyone! İndividuals who have any of the above risk factos may experience eye symptoms with even minimal screen time. For example, contact lenses or prior LASIK eye surgery can exacerbate dryness and irritation, medications such as antihistamines or antidepressants could cause eye dryness, and low humidity environments such as for example office buildings with blowing air-con or heat may also trigger attention irriation. Symptoms of eye dryness and strain could be aggravated by a number of other exposures in our daily lives.

The big thing to know is that you don’t have to suffer with symptoms. Simple measures such as those listed above can help. I also suggest seeing your eye doctor for a formal examination, to be able to think of a treatment plan that works for you personally and your lifestyle.

“Computer Vision Syndrome” has been coined to describe outward indications of sore eyes, dry eyes, teary eyes, blurry vision, double vision, light sensitivity, difficulty concentrating on images, neck pain, headache or a combination of all the above. Do you visit a lot of patients can be found in complaining of this?

All the time. And its occuring in younger and younger people as well. Computer vision syndrome is extremely common, and only increasing as our worlds continue to revolve around screens. I ask all my patients what they do for work, and when they work long hours at a screen, because its a significant part of my eye assessment.


Most people are happy to hear its not really a symptom of anything more serious with their eyes or whatever may cause permanent damage.


What’s great is we’ve ways of treating these symtoms, to really get your vision clearer and eyes more comfortable again. But computer eyesight syndrome and eye dryness could be long term and even lifetime conditions, which explains why its important to see your eyesight care provider for assessment.


Does how far away the screen is from your eyes influence the level of damage done?



It is usually recommended to sit an arms length from a desktop computer as that is most ergonomic positioning for the body. Placing the screen so that your eyes come in slight down-gaze may help with eye dryness a goodd irritation, as the eyelids will be minorly lower and within the surface of the eye.


Is damage to your eyes from screens permanent, or can it improve over times of looking at screens less?

Luckily, there is no ksimply nown permanent harm to the eyes from prolonged screen use.

Its all about treating symptoms early, modifying screen use and using tips like the 20-20-20 rule to make sure that signs and signs and symptoms don’t worsen as time passes. Regular eye examinations are essential to ensure the visions remain healthy, and for monitoring for just about any other forms associated with eye disease. The pc vision syndrome effects are usually caused by exactly how people use their own screens rather than usually by anything from the screens. In your personal opinion, do they actually work? Unfortunately, it is often impossible to decrease completely on screen period, but being cognizant of total time with digital devices and using some of the above tips can prevent you from developing symptoms, or will help prevent them from getting any worse after a while.

UV+ Blue Blocking glasses claim to provide defense against devices and synthetic light while having the ability to be worn such as for example regular eyeglasses. Long-term exposure to high energy glowing blue and UV lighting may contribute to the introduction of skin cancer, cataracts, or macular deterioration.

If your eyes are regularly red, painful, delicate to light, or maybe the vision is constantly blurry then I recommend seeing a watch care specialist to have an examination. Phone use ought to be thought of as getting the same effect on the eyes are pc screens.

Even though making use of screens can impact your own eyes, their make use of is unavoidable- our own worlds revolve around screens.


One question that a lot of the patients ask could be the concerning the effect of azure light on the attention from computers along with other screens. In fact, the biggest amount of blue light exposure comes from sunshine, and so I usually tell patients to put up sunglasses when outside to guard from ULTRAVİOLET exposure – consider them as sunscreen for the eyes plus eyelids! All digitial devices – cell phones, tablets, computers, laptops – can result in computer vision syndrome, attention dryness, and strain. The total period allocated to many of these gadgets is highly recommended once you expereience symptoms of computer v will be ion signs and symptoms. You can skip the particular ads for eyeglasses that claim to protect eyes from blue gentle exposure from displays, because the United states Academy of Ophthalmology will not recommend these kinds of.

As phone make use of has increased over the past couple of years, have more patients are available in with eye problems?

For this reason it is important to understand the risks of improved screen time, also to be prudent regarding treating any eyesight symptoms early.

Nevertheless , there is no evidence that will blue light publicity from screens will be damaging to the eyes.
