If you spend many hours in front of the PC, your days are likely to follow a regular pattern. You may feel pretty good when you wake up, but at the end of the day you get headaches, red eyes and a general feeling of tiredness.

One reason may lie in incorrect postures, incorrect monitor positioning and other physical problems. Another reason, however, could be due to the visual fatigue caused by the use of the computer, which affects 90% of intensive PC users.

Asthenopia (scientific name of visual fatigue) occurs when the eyes are focused on an object at close range (such as a cellphone or PC monitor) for so long as to strain the eye muscles.

Over the course of the day, the eye muscles become fatigued and lose the ability to focus optimally. Over time, muscle tension increases, blinking decreases, general discomfort and various other symptoms occur.

Eye Strain Symptoms

If you are not entirely sure that you are suffering from eyestrain, check the following symptoms, and think if you have suffered from it, when you have used your PC, for more than three hours:

1. Visual fatigue

In mild cases, fatigue can present itself as a difficulty in focusing on objects, particularly when refocusing quickly from one distance to another. When it gets worse, visual fatigue can lead to eye pain or discomfort.

2. Sore eyes

At first it may feel itchy, but when the condition worsens the eyes may start to burn. Significant redness may even arise. All these signs indicate that the eyes are drying out.

3. Vision clouded

Text and images become confusing even when it appears that the eyes are focused properly. Alternatively, you may see us double. If fatigue syndrome is responsible, the fogging will go away after a little rest.

4. Headache or dizziness

Both headache and dizziness are signs that visual computer fatigue has turned into something more serious. You should get a doctor to check if these symptoms last longer than a day.

5. Neck and shoulder pain

As your eyesight deteriorates and the discomfort increases, your body will adjust itself subconsciously so you can see better. This behavior leads to incorrect posture that affects the neck, shoulders and even the back.

How To Reduce Eye Strain?

It is better to deal with the problem as soon as the eyes seem tense or sore, instead of dragging it for weeks, months or years. Healing is possible as soon as the problem is addressed.

Typically, eyestrain is temporary and begins to resolve when you no longer use your computer or mobile phone. In lighter cases, the eyes will return to normal in a few hours or the following morning.

1. Use artificial tears

For immediate relief, you can use artificial tears, easily purchased in the pharmacy or online. Computers cause dry eye syndrome because they decrease blinking when fixing the monitor: less blinking, equal less eye lubrication. Drops can instantly relieve dry, sore and itchy eyes.

2. Check the humidity level in the room

The drier the environment you are in, the faster the moisture will evaporate from your eyes. The ideal percentage of ambient humidity for computer workers is between 30 and 50%.

3. Follow the 20-6-20 rule

Every 20 minutes observe something that is 6 meters away for at least 20 seconds. Giving the eye muscles some rest can put off – or even avoid – the onset of eye strain and strain.

4. Place the monitor in the best possible position

At a minimum it should be at an arm’s distance (about half a meter) from the eyes. When you look straight ahead, your eyes should line up with the top of the monitor. In general, the eyes should look down on the top.

5. Watch out for screen brightness

When in doubt, better lighter than darker. A brighter screen causes the pupils to narrow, which increases the focal range and allows the eyes to focus on the screen with less effort. Then, better big fonts than small fonts.

6. Purchase of a pair of glasses for use with computers

Consider, if you don’t already have them, the purchase of a pair of glasses for use with computers. This type of glasses is like those for reading, but they are more suitable because they facilitate focusing and require less effort. You can buy a couple from a pharmacy or supermarket, but the ideal thing would be to have a prescription prepared by your trusted ophthalmologist.

7. Eat foods that have a positive effect on the eye

Take a few breaks to eat foods that have a positive effect on the eye. The berries are excellent: you could drink blueberry juice which is a real cure-all. Just as dried fruit, citrus fruits and eggs can be excellent for maintaining correct functionality of the eye components.


If you find you have symptoms of eyestrain, implement some of the above-mentioned methods to reduce eyestrain or prevent it altogether. If you find that these approaches don’t help your eyestrain, consult your doctor.
