Eye strain is a common condition in which your eyes may feel tired or irritated after focusing intensely on activity like viewing a computer screen, reading a book, or driving a car for a long period of time. Eyestrain caused by the use of digital devices (prolonged use) like computers, smartphones, and tablets is better known as computer vision syndrome or digital eyestrain. Viewing a digital screen is much more visually demanding on the eyes than reading a printed paper.

Computer vision syndrome / CVS  is associated with the following symptoms –

  1. Dry eyes
  2. Headaches
  3. Blurred vision
  4. Time lag in focusing from distance to near and vice versa
  5. Neck and shoulder pain


Generally, eyestrain can be treated with simple, non-invasive methods. Treatment includes preventive measures, vision correction, and medications in the form of eye drops. There are some simple things you can do to help prevent eyestrain. Some of them you can even start doing today.

20-20-20 rule:

While using a digital screen take a break of only 20 seconds every 20 minutes and try to look at distant objects at least 20 feet away. This helps in relaxing the internal eye muscles and decreases the accommodative stress.

Location of the computer screen :

Make sure you’re looking at your digital device at the correct distance and in the proper position. The screen should be a few feet away from your eyes, or about arm’s length. You should view the screen at the level of your eyes or slightly below them. This goes for handheld digital devices, too: They should be read at below eye level

Lighting :

Depending on the activity, too bright or too dim light can cause eye strain. Make sure the screens that you’re viewing are adequately lit as well. Adjust the brightness as needed. Light should come from behind you if you’re focusing intensely on something like reading. Position the computer screen to avoid glare, particularly from overhead lighting or windows. If there is no way to minimize glare from light sources, consider using a screen glare filter. These filters decrease the amount of light reflected from the screen

Wear proper eyewear:

You may use specialized lenses, devices, or eye therapy for the activity that causes strain after ophthalmologist opinion. Certain coatings and tints for lenses may help your eyes. Or you may find that you need to cut the time you wear contact lenses to help rest your eyes.

Working environment :

Dry or polluted environments and places with fans and heating and cooling units may cause eyestrain. You may :

  • Improve the air with a humidifier
  • Turn down the heating and cooling system
  • Relocate to a spot that doesn’t have the same air issues

Use of Lubricating eye drops:

Intense focus, particularly when viewing a screen, can result in a dramatic reduction in how many times you blink per minute. When you blink less, your eyes can get dry and irritated. You can also try to blink more often when using a screen, which can prevent the symptom from occurring or different medicines in the form of lubricating and anti-inflammatory eye drops are available for managing different categories of dry eyes. Your eye specialist can help you choose the right medicine that suits your condition.

We, at DREI, have been providing large number of consultations to patients in all age groups with symptoms related to dry eyes and CVS due to excessive exposure to screens.
