Introduction– Computer Vision Syndrome Cure

Computers have become inseparable entities in our daily life. Many of us use computers for educational purpose, learning new things, browsing, shopping, or computer professionals use computers for extended hours as a part of their job.


Computer Vision Syndrome cure -(Digital Eye Strain) Definition


Computer vision syndrome is a set of eye symptoms and eye disorders resulting from focusing on computer screen for prolonged hours.

There are thousands of misconceptions existing today, some of which are pertaining to eye weakness and computer use, computer leading to excessive strain or for that matter excessive reading leading weakens your eyes.

As already said these are misconception which is wide-spread and readily accepted by all of us. These misconception regarding computer use and eye weakness are without any proof, and unfortunately are followed religiously and propagated by everybody one of such wide spread myth is that, too much of reading or too much working on computers is harmful for eyes.

But there is a catch to it, too much of reading or working extended hours on computers is harmful for eyes, is an incomplete statement, when we complete this statement, the meaning and understanding completely changes.

Let us complete this…………… too much of reading or working for extended hours on computers is harmful for eyes  “if performed under improper  and unhealthy conditions”. This important key factor is always missing in our understanding.

In this article we will discuss in detail the meaning of “improper and unhealthy conditions” which are primarily responsible for straining of eyes and also can lead to various damaging eye conditions in the long run.computer vision syndrome symptoms image 20computer vision syndrome symptoms image 34

Let us discuss these factors which are responsible for causing eye fatigue, eye strain  and eye discomfort ,under the following headings,

  • Eye strain, eye fatigue and eye Glass prescription(Digital Eye Strain)
  • Eye strain, fatigue and lighting conditions-(Digital Eye Strain)
  • Eye strain, fatigue and proper positioning of computer monitor-(Digital Eye Strain)
  • Eye strain, fatigue and anti-reflective coating-(Digital Eye Strain)
  • Eye strain, fatigue and air-conditioning-(Digital Eye Strain)
  • Eye strain, fatigue and colour of wall-(Digital Eye Strain)
  • Eye strain, fatigue and protective eye wear-(Digital Eye Strain)
  • Eye strain, fatigue and eye exercises-(Digital Eye Strain)
  • Eye strain, fatigue and contact lenses in computer users and computer professionals.
  • Eye strain, fatigue and computer vision syndrome-(Digital Eye Strain)
  • Eye strain, fatigue and dry eyes.

Computer vision syndrome cure  – Glass Prescription

If you have a refractive error (glass prescription), then it is very essential for you to get your eyes examined from an eye doctor- eye consultant at regular intervals. As any change in the eye prescription will itself produce strain in your eyes which will get further exaggerated and it will add to the problem in the form of eye fatigue and eye blurring and in turn will lead to strain in your eyes.

In this case computers are not at fault but your improper glass prescription is responsible for causing excessive strain which will eventually result in fatigue, discomfort and eventually you will land with decreased productivity. If a computer professional has glasses then it is must for him or she to get eyes periodically checked, for any change in glass prescription. This is the first and the most important reason which we encounter as eye professionals in our practice.

computer vision syndrome symptoms image 22

If a computer professional who didn’t had any glasses to begin with has now began to experience strain, even in this case the first and foremost step is to get your eyes checked for any glass prescription which can develop due to many reasons like development of cataract, any disease which is compromising the eye health, any general body condition which is secondarily affecting the eye health, or else it could be a simple near work prescription which tends to develop at around age of 40 years.

Some of us had glass prescription but it was very small to begin with, and it never bothered us in our daily lives but as the age advances, this small glass prescription will also become significant as our eyes will not be able to adjust without them during the extended hours of working with computers.

So even the minor glass prescription will become significant and might be responsible for the fatigue and discomfort which is commonly faced by computer professionals during their working hours.


Computer vision syndrome cure and Improper Lighting-

Improper lighting is the second most important factor which is commonly observed reason for eyecomputer vision syndrome symptoms image 34 discomfort, eye fatigue and eye strain amongst computer professionals.

This improper lightning can occur from surrounding source of light like sunlight, or Fluorescent lamp tubes, or from your computer monitor itself.

Always make sure that no strong bright light or bright sunlight is entering your room where you are working with computers.

This will not only distract you while working but will also create excessive strain on your eyes as your eyes have to adapt to lights of different intensities multiple times.

computer vision syndrome symptoms IMAGE 23

This is very commonly experienced by all of us in our daily life –for example do you remember the last time you walked out of a movie hall after watching a movie, and as you stepped outside, the bright daylight which usually in our daily life causes no problem suddenly, become intolerable for a fraction of a second and later after few moments you were fine and the light become tolerable again.

This phenomenon is called as adaption, only difference is, in our example we compared the dark light inside movie hall and the bright usual day light and in the same way while working on computer we have to adjust to the light of the monitor and also to the bright sunlight which is entering our room, cabin or working space.

Our eyes are very well tuned for adaptation to light, but if this was to happen very frequently while you are working on computers, it will cause a momentary but frequent disturbance and if this happens frequently then eventually you will perceive it as eye fatigue, eye discomfort and eye strain.

You can always adjust the settings of your monitor’s display so that it can be very comfortable for your eyes. It is must for all the computer users and the computer professionals to adjust to their display settings so that brightness contrast and the cool and warm colours are sufficiently adjusted so that they do not produce any undue strain on eyes.

computer vision syndrome symptoms image 10

Mostly this very simple step is always ignored. You forget to adjust the display settings and continue to work on the default factory settings.

This simple readjustment of the factory settings can help you in getting a very comfortable and pleasant vision without any discomfort. Henceforth don’t forget to readjust factory settings of a new monitor or of any monitor before beginning your work on computer.

       Computer vision syndrome cure  – Eye fatigue and air-conditioning  (environmental – temperature)

The temperature in your office where you are working on your computer is yet another important factor in the generation of eye fatigue, eye discomfort and eye strain.computer vision syndrome symptoms image 31

The basic problem here is the evaporation of tears which occurs from the surface of our eyes leaving our eyes completely or partially dry. This dryness of eyes creates eye discomfort, itching, foreign body sensation, eye fatigue and this eventually leads to eye strain.

When we are completely focused on our work on computer at times we forget to blink and this leads to excess evaporation of tears from the surface of the eyes.

Blinking is our body’s natural   reflex…This reflex comes in to play for protecting our eyes from foreign bodies entering in the eye and blinking reflex also helps in evenly spreading of tear film over the surface of our eyes.

Definitely frequent blinking or should I say frequent blinking consciously will be helpful in preventing evaporation, but along with that if we are able to regulate the surrounding temperature and make it as close as possible to a comfortable room temperature rather than working at extremes of temperature.

Normal comfortable room temperature with frequent consciously blinking of eyes, these two steps are very powerful and are extremely helpful in preventing lot of future eye problems.

Computer vision syndrome cure  –Eye fatigue and eye exercises-

computer vision syndrome symptoms image 8While working on computers for long hours, we tend to concentrate and focus on the computer screen to get our job done, but while doing so, the eyes remain focused at a particular near position, in other words we can say ,eye focus is locked , at a particular object for a long time.

This particular blocking of focus for long time is the major factor leading to generation of eye strain. Constantly focusing at a particular object without any shift of focus tends the eye to remain in a locked position without any relaxation, for quite some time.

And because of this prolonged locking of eyes, the eye goes into fatigue. To prevent this eye fatigue one has to relax the eye focus and this is achieved by focusing or looking at a distant object.computer vision syndrome symptoms image 21

Looking at a distant object will immediately break the eyes locked focus and this breaking of the near focus itself leads to relaxation of eyes. Focusing at a distant object momentarily will not cause any strain on eyes as our eyes are naturally meant to view a distant objects without any strain.

computer vision syndrome symptoms IMAGE 14

We usually suggest the rule of 20-20-20, that is after every 20 minutes of concentrated work on computers screen, take a break in the form of looking  at a distant object  (approximately 20 feet away) , for a duration of approximately 20 seconds.

These are approximate values not to be taken rigidly; the basic idea is to move your attention away from the computer screen to any distant object so the focus is broken and thus leading to relaxation of eyes.

After doing so you can again resume your work, and if this is done periodically as suggested you will experience that you are able to concentrate for long hours without any eye fatigue, eye discomfort or any other eye problem for long hours, merely by taking these short breaks.

This is a simple but very powerful tip for your eyes, while working on computers for prolonged hours.

While working on computers the display of the monitor should never be kept at high brightness or at high contrast. If you ever noticed your monitors display is glowing like a source of light that means you are working under excessive brightness. Ideally the brightness of the computer screen should be equal to the brightness of the surroundings where monitor is placed.

Computer vision syndrome cure –Eye fatigue and Contact Lenses in computer users and computer professionals.

This is a very common scenario which is encountered in our day-to-day life. There are number of contact lens users who also happen to be computer professionals, and most of them use contact lenses for cosmetic purposes or because they are suffering from a very high refractive error and are not very comfortable wearing spectacles while working on computers.

computer vision syndrome treatment image 3Uses of contact lens, How to use contact lenses, How to take care of contact lens, How to select contact lens etc. these are the topics which are discussed elsewhere on our website , and will not be discussed here.

Those who are interested to, read about the same can visit our website-” pediatric ophthalmologist and neuro-ophthalmologist in mumbai

But while working on computers with contact lenses there are set of instructions which must be followed. Doing this will help you in achieving the maximum benefit of contact lenses and so that you can experience comfortable vision without causing any discomfort or harm to your eyes.

First of all, the contact lens wearers must get their eyes examined and must reconfirm their glass prescription periodically and accordingly determine the power of the contact lens for their further use.

A contact lens which is not of a proper suitable prescription is destined to give eye fatigue, eye discomfort and eye strain. So it is very essential for such contact lens users to get their eyes periodically examined from a qualified eye professional or an eye doctor.

Make sure that your contact lenses are fitting properly. And this is how you can determine a proper fitting contact lens for your eyes. A properly fitting contact lens will never lead to foreign body sensation or any kind of discomfort in your eyes. If they are causing any kind of such problem that means it is probably not a proper fit for you and you need to change the size of your contact lenses. Any kind of frequent watering from the eyes after wearing contact lenses also points towards an improper fit.

Considering all the fitting parameters are proper and still a computer professional is having discomfort with computer vision syndrome symptoms image 32the contact lenses while working on computer, this might be pointing towards some kind of allergy to a particular brand of contact lens or allergy to the particular material of contact lens or allergy to the cleaning solution of the contact lenses. If such an event occurs ,consult your eye doctor.

If you’re using contact lens over an extended period of time which are out of range as advised by your eye care professional will also lead to eye discomfort while working on computers.

For all the contact lens users the most important tip which I can think of is to discontinue their contact lenses immediately if they are facing any of the problems which are mentioned above.

Any kind of redness watering foreign body sensation discomfort to the eyes itching discharge all these are red flags for use of contact lenses and must be immediately discontinued.

One needs to take an eye care consultants advice regarding the same, identify the problem, identify the source, get the problem solved and only after your doctor’s advice you can continue using your contact lenses later.

Any kind of glare or distortion of image or blurring of image might be pointing towards wearing off of your contact lens material.

Contact lenses must be changed as per the type of the contact lens you are using may be daily disposable, monthly disposable, quarterly disposable etc… They should be disposed of as advised by the manufacturer and should never be used beyond suggested period.

Computer vision syndrome cure –Eye fatigue and Dry Eyes.-

Dry eyes  is a condition which occurs when the tear secretion of our eyes is reduced beyond a certain limit. These reduce the tear secretion is unable to cover the surface of our eyes and provide necessary lubrication and hydration to the surface of the cornea.

Cornea being a very sensitive structure reacts immediately to any reduction in hydration or dryness.The health of the cornea is totally dependent on the normal hydration which in turn will determine the clarity and the quality of your vision.

If you are constantly suffering from dryness of your eyes especially when you are working on computers than it is must that you consult your eye care professional and get examined for dry eyes.

computer vision syndrome symptoms image 18Once the condition is diagnosed, lubricating eye drops are prescribed depending on the state of the eyes and dryness. Frequent use of these lubricating eye drops will help the patient of dry eyes to a certain extent to give them comfort while working on computers; contact lenses are absolutely contraindicated in such patients.

Beyond this discussion on dry eyes is out of scope of this article, interested readers can visit our website to get detail information about the same.

Computer vision syndrome cure –Eye fatigue and anti-reflective coating

Antireflective coating-it is thin film of coating which is applied over optical lenses, and other optical elements to decrease the stay light, and cut down the destructive interference .doing so very less light is lost and the contrast of the resultant image produced is very good.

Cosmetically this lenses coated with antireflective coating is very appealing. Also it takes care of the ghost images formed at the anterior and posterior surface of lens, thereby reducing the confusion. In short antireflective coating of optical surface is beneficial for the system and our eyes.                                                computer vision syndrome symptoms image 29

For all those computer users or computer professionals who are working on OLD generation CRT type monitors must get their display covered with the antireflective coating or antireflective film.

Most of the latest LCD monitors they have an inbuilt antireflective system which helps in giving more comfort to your eyes while you are working on computers. If you are not very sure about this, please refer to monitors manufacturer manual.

Since most of the latest monitor displays have got this antireflective coating and is very common nowadays, further detail discussion is deferred.

Computer vision syndrome cure-Eye fatigue and protective eye wear-

If it is not possible for a computer professional to change his CRT type monitor due to company policies, one can use a spectacle, with antireflective coating also called as ARC .

computer vision syndrome symptoms image 15This will also help you in getting rid of the ghostly images which are formed over the front surface and the back surface of your spectacle lenses. These ghost images leads to minimal confusion and a distraction and eventually leads to eye strain.

So it is a very good idea for a spectacle user who is a computer user or a computer professional to get an antireflective coating for comfortable working hours on computer.

 Eye fatigue and computer vision syndrome cure – Computer Vision Syndrome Cure

Computer vision syndrome or digital eye syndrome is commonly searched on Google search. This entity is not just a not a single eye problem but it is a collection of one or more of the eye problems which we have already discussed above. These signs & symptoms are collectively called as computer vision syndrome.

In one study it was documented that around 90% of computer professionals or computer users have some kind of eye problem which might range from mild discomfort of eye to painful eyes and headaches.


Computer vision syndrome in kids-(Digital Eye Strain)-Computer Vision Syndrome Cure


computer vision syndrome symptoms image 12

One important information which needs special mention, it is not that only grown-ups are suffering from computer vision syndrome but it involves kids as well. In the modern world ,kids are known to work On computers, tabs, mobiles .

They perform activities like projects ,homework, study ,browsing  and  gaming for long hours under improper lighting conditions with  improper posture. Surely they are going to have computer related eye problems in future.

This all begins with the mild discomfort in eyes while working on computers which is ignored and this discomfort is allowed to persist and is repeated over and over. This mild discomfort to begin with is nothing but a warning sign which is often neglected and the computer professional continues to ignore this and eventually lands up with a major problem called as computer vision syndrome.

The warning signs which all the computer professionals must be aware are as follows-

1.  computer vision syndrome symptoms image 26Blurred vision while working on computers

2.  Headaches while working on computers

3.  Dryness of eyes while working on computers

4.  Redness of eyes while working on computers

5.  Watering of eyes while working on computer

6.  Double vision while working on computers

If a computer professional ignores this warning signs and continues to work, the resulting ill effects produced will not only harm his eyes but also it will decrease your productivity. So these warning signs should not be ignored and a proper consultation from your eye care consultant and treatment for the same should be initiated immediately.

Eye fatigue and proper positioning of computer monitor  – Computer Vision Syndrome Cure

computer vision syndrome symptoms image 17

It is very important for one to realise and make sure that the monitor must  be positioned slightly below the eye level and should not be very close to your eyes. Ideally the monitor should be placed at around 20 to 28 inches away from your eyes. Close to this or further away from this will surely produce eyestrain over a period of time.

computer vision syndrome symptoms image 28computer vision syndrome symptoms image 25computer vision syndrome symptoms image 2

If a computer user has to work on a computer screen along with physical hard copy of a document then the best practice is to keep document holder, next to your screen.

This is a simple tip which most of the computer professionals either don’t know or they don’t practice, but not doing so over a period of time will produce eyestrain because of repeatedly focusing & refocusing of our eyes at different distances for example if the document is placed on the table and the computer user has to repeatedly shift his focus from the computer screen to the document which is placed on the table.

This is a common scene in computer industry ,the computer user is repeatedly moving his head up and down ,unaware of the continuous adjustments which our eye has to make, continuous focusing and refocusing at different distances leading  to eyestrain, eye fatigue, headache and eye discomfort, which will harm your eyes and also lead to decreased productivity.

computer vision syndrome symptoms image 13

Continuous moments of your head from your computer screen to the document on table will eventually lead to neck pain and over a period of time can become serious and a permanent problem.

A simple stand holder or a document holder placed beside your screen can help you in getting rid of all such problems and make your work more enjoyable and comfortable.


CONCLUSION- Computer Vision Syndrome Cure

In conclusion, Computer vision syndrome is a major eye problem which affects 50-90%of computer professionals and computer users.it is wise to be aware of this problem and take preventive steps so that you can safely continue your profession without becoming a victim of this troublesome disease. Just taking few corrective measures and making changes in your working style and working posture will make a big difference in your productivity and creativity, and will ensure that you don’t fall prey to this disease.
